Key Highlights

• Up to one in five consumer deliveries fail on the first attempt; mismatched or incorrect billing and shipping addresses are frequent causes of payment declines and delivery exceptions.
• Accurate address collection, verification tools, checkout UX design, and carrier integrations reduce costs, speed fulfillment, and protect against fraud.

Introduction

A single misplaced digit or an out-of-date street name can ripple through an ecommerce operation, creating late deliveries, returned parcels, frustrated customers and extra expenses. Research published in Production and Operations Management finds that as many as one in five business-to-consumer deliveries fail on the first attempt. That failure rate reflects a mix of operational issues, but address errors and payment mismatches rank among the most avoidable causes.

Online merchants often treat billing and shipping addresses as incidental fields in checkout. They are not. Each plays a distinct operational role: the billing address validates the payment and protects against unauthorized use of a card; the shipping address determines the physical route, carrier selection, pricing and final-mile outcomes. When those pieces are wrong or mishandled, the effects show up as higher delivery costs, greater customer-service volume, and the erosion of repeat business.

This piece explains how billing and shipping addresses differ, why mismatches matter for payments and logistics, the range of address-related errors that occur in practice, and the technical and operational steps merchants of all sizes can take to reduce failures. Practical examples, implementation priorities and measurement tactics give teams a clear roadmap for turning address accuracy from a recurring headache into a controlled, measurable process.

What billing and shipping addresses actually do

Two fields. Two separate purposes.

• Billing address: Tied to a payment instrument, the billing address serves as an identity check between the customer and the card issuer. When a shopper enters card details online, the billing address is compared to the address on file with the issuing bank. If the addresses don’t match exactly, the payment processor may decline the transaction or flag it for further verification. That verification step deters fraud and unauthorized use of stolen card details.
• Shipping address: This is the physical destination for the parcel. Carriers and fulfillment teams use the shipping address to calculate rates, plan routes, estimate delivery windows and determine whether special handling is required (for example, customs documentation for international shipments, or access codes for gated communities). The shipping address is validated against postal and carrier databases, not the card issuer’s records.

Treating these two addresses as interchangeable creates operational risk. For example, a legitimate customer may use an employer-issued card that lists the billing address at the cardholder’s home, while the package needs to go to a remote job site. Validating the card requires the billing address; routing the package requires the shipping address. Each system must be right for its purpose.

Why an address mismatch matters: payments, fraud and delivery failures

Address mismatches generate three core failure modes for online orders: payment friction, delivery exceptions, and customer dissatisfaction.

Payment friction: Payment gateways and issuing banks rely on address checks as part of their fraud-detection stack. When the submitted billing address does not match the bank’s records, transactions often decline or trigger additional authentication requirements like one-time passwords or 3-D Secure challenges. These interruptions increase cart abandonment and force customer-service intervention.

Fraud prevention: Address Verification Service (AVS) and address-match checks reduce chargeback exposure by making it more difficult to use stolen card data. Attackers often attempt transactions with mismatched addresses; a robust AVS policy stops many such attempts at the checkout gate.

Delivery exceptions: Shipping address errors lead directly to misdeliveries. A single typo in a postcode, an omitted apartment number, or an outdated saved address can cause a parcel to be delivered to the wrong unit, held at a depot, or returned to sender. Re-deliveries and returns add direct costs for carriers and merchants, and indirect costs in labor, reshipment and negative customer experiences.

Customer churn and reputation: Customers who experience a missed delivery or a payment decline during checkout are less likely to purchase again. The immediate cost is the reshipment and service time; the longer-term cost is lost lifetime value. For high-frequency retailers, a small lift in address accuracy pays back through improved retention.

Operational inefficiencies: High error rates force teams to triage exceptions instead of focusing on growth activities. Customer-service time spent correcting addresses, contacting carriers, and issuing refunds scales with order volume. That labor expense can exceed the marginal cost of improved validation tools.

These consequences manifest differently depending on business size and model. A subscription box service that ships weekly sees cumulative damage from repeated delivery failures. A luxury retailer handling high-ticket one-off sales faces immediate revenue risk from payment declines. Both benefit from distinct but complementary solutions.

Common shipping address errors and how they happen

Address problems appear in many forms. Operational teams should catalog and prioritize the ones they see most frequently.

• Typos and transpositions: Misspelled street names, swapped digits in apartment numbers, and transposed postal codes are frequent when customers enter addresses on mobile devices or under time pressure.
• Incomplete addresses: Missing apartment, suite or unit numbers; omitted PO Box indicators; or absent locality fields (neighborhoods, business parks) leave carriers guessing. Some countries require very specific elements to route mail correctly.
• Outdated saved addresses: Customers who store addresses on a site and later move may forget to update profile information. Auto-filled forms that draw from old data increase the chance of shipping to a former residence.
• Billing equals shipping by default: Many checkout flows copy the billing address into the shipping address field. Customers who forget to change it can send packages to the wrong location.
• International format errors: Address formatting varies by country. Japanese addresses often start with the postal code; many European addresses place the building number before the street name. A merchant using a U.S.-centric address form may accept addresses that carriers cannot parse or match.
• Rural and non-standard addresses: In some regions, addresses are descriptive rather than numeric (e.g., “5 km from the main road, next to the red church”). Carriers depend on local knowledge or geocoding to resolve those to a delivery point.
• PO Boxes and APO/FPO limitations: Carriers may be unable to deliver standard parcels to PO Boxes or military addresses without special handling, or a merchant’s serviceable area may exclude these destinations.
• Gate, access and delivery instructions missing: Especially for multi-unit complexes or secure facilities, missing entry codes, floor numbers or receptionist instructions will delay delivery and increase failed attempts.
• Carrier-specific formatting and abbreviations: USPS, Royal Mail, and national carriers have different standards for abbreviations and postal code usage. Failing to normalize to carrier expectations can lead to exceptions.

Each error type requires a different mitigation: user-interface validation, backend normalization, carrier rules, or manual verification for edge cases.

Tools and technologies that reduce address errors

A combination of frontend UX, backend validation and carrier integration removes many address-related failures. Key categories:

• Address autocomplete and suggestions: Integrating a service like Google Places or a regional provider reduces typing errors and standardizes formatting. When customers select an address from suggestions, the result typically includes properly structured components (street, unit, city, postal code).
• Address verification services (AVS) at payment time: AVS checks the billing address against the card issuer’s records. AVS is not universal across countries but works in core markets like the U.S., Canada and the U.K. AVS reduces fraudulent transactions that use stolen card data.
• Postal and carrier validation APIs: Carriers provide APIs (UPS, FedEx, USPS, DHL) that validate and normalize addresses, check for PO Boxes, and in some cases provide delivery-quality indicators. These services are crucial for shipping labels and rate shopping.
• Change-of-address (NCOA) and remediation databases: National postal change-of-address services help identify when a saved address has a recent move. Integrating these periodically reduces shipments to old locations.
• Geocoding and latitude/longitude verification: Geocoding converts an address into coordinates. For difficult or rural addresses, geocoding helps carriers and fulfillment centers match the address to a delivery point or identify an ambiguous location for manual review.
• CASS and equivalent certification: In the U.S., CASS (Coding Accuracy Support System) certification verifies and improves address quality for USPS bulk mail. Global equivalents and postal standards help with bulk normalization and deliverability.
• Real-time carrier exception monitoring: Integrating carrier webhooks and tracking APIs lets merchants see early exception codes (e.g., “attempted delivery – no access”) and trigger customer notifications or rerouting.
• Machine learning for address parsing: For complex international addresses, ML models can parse and normalize free-text address inputs. These models also flag suspicious combinations (e.g., mismatched postal code and city) for manual review.
• Integration with payment authentication flows: When AVS triggers a mismatch, complementing it with 3-D Secure or tokenized wallet methods reduces false declines while maintaining fraud controls.

Combining multiple tools produces the best results. Autocomplete reduces human error; carrier validation ensures the address is deliverable; AVS protects payments. The challenge is designing the integration to avoid redundant friction.

Checkout UX and policies that prevent errors while minimizing friction

Address accuracy is a UX problem as much as a data-validation problem. Designers must reduce friction while collecting the required elements.

• Make purpose explicit: Clearly label fields as “Shipping address (where your order will be delivered)” and “Billing address (address on your payment method).” That simple distinction reduces accidental duplication.
• Use structured fields rather than a single address line: Separate fields for street number, street name, unit, city, state/province and zipcode help validation tools perform more precisely.
• Offer autofill but allow edits: Autocomplete gives customers a validated starting point; allow them to edit if necessary. Preventing edits entirely risks excluding legitimate use cases like rural addresses.
• Mobile-first optimization: Most shoppers use mobile. Design input controls that make entering apartment numbers and postal codes easy on small keyboards, including number-specific keyboards where appropriate.
• Default behavior: Decide whether shipping should default to the billing address. For many retailers, defaulting to the billing address increases conversion for single-address users but raises misdelivery risk for gift purchases or multiple-address customers. Consider making the shipping field empty by default, or using a single checkbox that is clearly phrased.
• Save addresses behind authentication with clear labels: When customers store addresses, allow them to label them (e.g., “Home,” “Work,” “Gym”) and encourage periodic review.
• Gift and alternate-delivery flows: If an address differs from the billing address, provide options for gift messages, different invoice behavior, and the ability to mark the shipment as a gift to suppress billing address exposure.
• Explicit confirmation step: Show order summary with shipping and billing addresses clearly displayed and require a single confirmation tap before payment. Even a small friction point here reduces downstream exceptions.
• Communicate delivery constraints: If a carrier or product cannot be sent to PO Boxes, show that restriction early in the checkout experience.

Design choices should align with business model. A high-volume fast-fashion retailer may prioritize minimal friction, while a high-value goods retailer prioritizes verification and fraud protection.

How fulfillment teams should handle address verification and labels

Checkout validation reduces most problems, but fulfillment operations must maintain a second line of defense.

• Automated label generation with carrier validation: Generate shipping labels through carrier APIs that validate the address at print time. This step catches last-mile incompatibilities and reduces manual fixes.
• Pick-pack-ship checks: Implement a simple double-check at packing where the packing slip is matched to the shipping label and scanned. Many fulfillment errors originate at the pick stage, not in the address itself.
• Barcode and order ID verification: Put order numbers on packing slips and labels, and ensure scanners verify that contents and destination match. This reduces instances where a package gets the wrong label.
• Staff training on address fields: Ensure packers and shipping clerks understand abbreviations, unit numbers, and how carriers expect addresses to be formatted. A small training program reduces label corrections.
• Manual review for flagged addresses: Create an exception queue for addresses that AVS, carrier APIs or geocoding flag as problematic. Customer service should confirm the intended delivery point before shipping.
• Return-label policy and process: If an item is returned due to an address issue, streamline the process for refunds and reshipment and use the return event to update the saved address or contact the customer. Use returns as a source of truth for address hygiene.

Operational discipline at fulfillment closes the loop between checkout data and physical shipments.

International addressing: formats, customs and common pitfalls

Expanding internationally introduces new address formats, customs requirements and failure modes.

• Different formats and ordering: Address structures vary. Example: Japanese addresses often start with the postal code and list prefecture and municipality in a specific order. In France, the building number typically precedes the street name. Allowing free-text international addresses without regional-specific parsing leads to unstructured data that carriers struggle to interpret.
• Postal code importance: In many countries the postal code is the most critical routing element. Ensure the checkout requires and validates postal codes according to the destination country’s format.
• Customs documentation: For cross-border shipments, an incorrect address combined with incomplete customs documents can cause a package to be held or returned. Ensure customs forms match the delivery address and include necessary tax-IDs if required.
• Local carriers and last-mile partners: Some local carriers require additional metadata or have restrictions on package dimensions and weight. Understand local carrier requirements before selling into a region.
• Address standardization services by region: Invest in regional verification providers for high-volume destinations. Global providers often do well in English-speaking markets but underperform in certain regions where local address registries and standards differ.
• Language and character sets: Allow customers to enter addresses using local character sets where necessary, and ensure your label generation supports Unicode or transliteration rules accepted by carriers.
• Example: Latin America and the Caribbean: Frequent use of landmarks and non-linear addressing requires integration with local carriers and optional delivery instructions. For instance, deliveries in parts of Mexico and Brazil may rely on local courier knowledge and specific locality fields.

International growth requires mapping your checkout form and back-end validation to the world’s address varieties. The cost of neglect scales with volume.

Carrier options and last-mile alternatives that lower failed-first-attempt rates

If delivery attempts fail because customers aren’t available, address accuracy is only part of the solution. Offering flexible last-mile options can reduce failed attempts.

• Scheduled deliveries and time windows: Allow customers to choose a delivery window at checkout. This reduces the probability of missed deliveries in urban areas.
• Parcel lockers and pickup points: Services like Amazon Hub, carrier lockers and local pickup points prevent failed attempts entirely by letting customers pick up on their schedule. Many European carriers and last-mile providers support dense locker networks.
• Alternative addresses and neighbor delivery: Offer the ability to designate a trusted neighbor or safe place. Combine this with clear liability policies.
• Local pickup: For omnichannel merchants, offer in-store pickup or click-and-collect. One missed first attempt converts into a customer visit instead.
• SMS and mobile notifications: Real-time alerts that allow a recipient to reroute or reschedule delivery reduce unsuccessful attempts. Integrate carrier tracking webhooks to trigger those messages early.
• Delivery instructions and access codes: Collect secure instructions for gated residences or workplaces, and store them in a privacy-conscious way. This avoids repeated attempts at inaccessible locations.

Flexibility in delivery models mitigates the impact of address problems on initial delivery success.

Measuring and reducing first-attempt delivery failures: KPIs and root cause analysis

You cannot fix what you don't measure. Track the right metrics and analyze failures by root cause.

Primary KPIs:

• First-attempt delivery success rate (percentage of parcels delivered on first attempt)
• Payment decline rate attributable to AVS/address mismatches
• Reship and return rate due to address errors
• Customer service tickets per order related to address or delivery issues
• Average cost per failed delivery (including reship, call-center time, and refund)

Secondary metrics:

• Time from order to exception detection
• Percentage of orders passing AVS and carrier validation at checkout
• Percentage of saved addresses updated after a failed delivery

Root cause analysis approach:

1. Segment failure reports by exception code supplied by carriers (e.g., “unable to locate address”, “access blocked”, “incorrect address”).
2. Reconstruct the checkout data versus the shipping label printed: was the typo introduced in the order, or during label generation?
3. Identify patterns tied to specific products, shipping zones or checkout flows.
4. A/B test different checkout interfaces and validation settings to see if failures decline.

Use these analyses to prioritize interventions. For example, if a region shows a high “unable to locate address” rate, invest in geocoding or a local carrier integration for that market.

Cost-benefit thinking: how to justify investments in address hygiene

Address-validation tools and checkout improvements are investments. Presenting a business case requires estimating both costs and savings.

Cost side:

• Subscription and per-request costs for autocomplete, AVS and carrier-validation APIs.
• Development and integration time.
• Potential small losses from increased checkout friction if validation becomes too strict.

Benefit side:

• Reduced reshipment and return expenses.
• Lower customer-service labor for address-related cases.
• Fewer chargebacks when payment validation stops fraudulent purchases.
• Improved customer retention from reliable deliveries.

A simple approach for merchants:

• Calculate the margin impact of a single failed delivery: carrier fees for return and redelivery, cost of refund and restocking, plus average customer lifetime value lost from churn if the customer does not reorder.
• Multiply by the annual number of address-related failures to estimate total loss.
• Compare that to estimated annual cost of validation tools and integration plus ongoing operational costs.

Often the breakeven is quick for high-volume merchants. Small merchants can start with low-cost tools (autocomplete, confirmation emails) and scale up to AVS and carrier integration as volume grows.

Operational checklist: practical steps every merchant can implement now

Short-term actions (low effort, high impact)

• Add a clear shipping vs billing address label and checkbox.
• Enable address autocomplete on checkout.
• Send an immediate order confirmation email that displays shipping details and a simple “edit address” link for a short window.
• Train customer-service staff to immediately correct addresses on new orders when called.

Medium-term actions (moderate effort)

• Integrate a postal/courier validation API at label-printing time.
• Put an exception review flow in place for flagged addresses.
• Implement NCOA updates for saved addresses.

Longer-term actions (higher effort)

• Implement AVS and coordinated payment authentication flows.
• Add geocoding and address-normalization services for key international markets.
• Offer scheduled deliveries, locker pickup and localized last-mile partners.

Prioritize by volume and value. Address hygiene is a continuous improvement program, not a one-off project.

Legal, privacy and fraud considerations

Combining address verification with payment authentication touches on sensitive customer data and regulatory regimes.

• AVS and payment data: AVS relies on comparing billing address inputs against issuer records. Implement payment authentication flows (e.g., 3-D Secure) to avoid unnecessary declines while preserving anti-fraud controls.
• Data minimization and privacy: Only store address fields required for fulfillment and fraud prevention. When using third-party providers, ensure data processing agreements and compliance with regional rules like GDPR.
• Consent for using third-party validation: Make sure your privacy policy outlines how address data may be transmitted to verification services and carriers. For regions with strong consent requirements, surface this during checkout or in the account settings.
• False positives and customer experience: Overly strict validation can block legitimate customers (false declines). Balance fraud rules with fallback verification methods like OTPs, phone callbacks or alternative payment methods.

Strike a balance between fraud prevention and friction. A measured, monitored approach minimizes both chargebacks and lost sales.

Real-world examples and scenarios

Below are anonymized and plausible scenarios that show how address mistakes affect operations and how mitigation steps yield results.

Scenario 1: The gift-order problem A boutique retailer sells handcrafted items throughout the country. During the holiday season, many buyers ship to friends and family. The checkout defaults the shipping address to the billing address; customers assume the retailer will notice. A significant share of holiday orders goes to buyers’ home addresses instead of the intended gift recipients. The result: customer complaints, returned items and emergency reshipments with expedited freight.

Fix: The retailer changed the default so shipping fields start empty and added a prominent “This is a gift” toggle. They also introduced an address-confirmation step and gift-message capability. Holiday-season reshipments dropped measurably and customer satisfaction rose.

Scenario 2: High-value electronics and AVS declines An electronics seller experienced a noticeable number of declined payments on large orders. Some declines were legitimate fraud attempts; others were valid customers using corporate cards that listed corporate headquarters as the billing address. Rigid AVS rules blocked both cases and increased abandoned carts.

Fix: The merchant implemented a tiered risk strategy: use AVS for low- and mid-ticket items but add a secondary verification flow for high-ticket purchases, such as an SMS OTP or optional call verification. That reduced fraud without increasing false declines.

Scenario 3: International format confusion A merchant expanding into France shipped thousands of orders with street numbers placed after the street name because the merchant’s checkout used a U.S.-style order. Many carriers could not automatically parse these addresses, causing delays and exceptions.

Fix: The merchant implemented country-specific address templates and supplier checks and integrated a carrier validation API that enforced the correct format for French addresses. Delivery times normalized, and customer complaints about missing deliveries decreased.

These scenarios show that small product or UI changes yield operational improvements across fulfillment and payments.

Future trends: where address handling is headed

Expect incremental improvements and a few discontinuities in the way addresses are collected and used.

• Better geolocation and coordinates-as-address: Some services will let users provide lat/long for delivery points, especially in regions with poor street addressing. Carriers and apps will increasingly accept coordinates for last-mile routing.
• Identity-linked addresses: Tighter integration between digital identity tools and payment instruments may reduce AVS friction while preserving anti-fraud controls. Tokenized wallets and bank-authenticated payment methods already reduce reliance on textual billing addresses.
• Smarter carrier routing: As carriers improve APIs and predictive routing, merchants can use delivery-quality indicators to route high-risk addresses through more reliable partners.
• More granular delivery options: Expect broader adoption of parcel lockers, contactless handoffs, and micro-fulfillment nodes that reduce dependence on a single failed first attempt.
• Machine-learning driven normalization: ML models will better parse global address types and flag improbable combinations, reducing manual reviews for high-volume merchants.

Preparing for these trends means investing in modular systems: build a verification layer that can plug into different providers and add new data sources as they become cost-effective.

FAQ

Q: What is the difference between a billing address and a shipping address?
A: The billing address is tied to the customer’s payment method and used to confirm payment authorization and cardholder identity. The shipping address is the physical destination for the order and used to determine shipping costs, routing and delivery handling.

Q: Can the billing address be different from the shipping address?
A: Yes. Customers frequently ship to alternate locations—workplaces, gift recipients, or temporary residences—while their card’s billing address reflects their account statement address. Systems must handle both correctly to avoid payment declines and misdeliveries.

Q: What happens if the billing address doesn’t match the bank’s records?
A: The issuer or payment processor may decline the transaction or require additional authentication. That prevents many fraudulent transactions but also causes checkout friction. A tiered verification strategy and wallet options can reduce false declines.

Q: What are address verification services (AVS), and how do they help?
A: AVS checks the billing address against the information held by the card issuer. It’s primarily a fraud-prevention tool. For shipping addresses, carrier and postal validation APIs perform similar checks for deliverability.

Q: Are autocomplete and address-suggestion tools safe and effective?
A: Yes. Autocomplete reduces typing errors and standardizes formatting. It is effective when paired with carrier-side validation because it speeds checkout and leaves the final deliverability check to specialized services.

Q: My business ships internationally—what special steps should I take?
A: Use country-specific address templates, validate postal codes, ensure customs documentation matches the shipping address, support local character sets when necessary and integrate local carrier partners for hard-to-parse regions.

Q: What quick wins can small merchants use to reduce failed deliveries?
A: Add clear labels distinguishing shipping from billing address, enable address autocomplete, send a confirmation email with an edit window, train staff to check labels at packing, and integrate carrier label validation if your shipping volume justifies it.

Q: How should I measure the impact of address-improvement work?
A: Track first-attempt delivery success rate, reship/return rates due to address errors, AVS-related payment declines, customer-service tickets related to addresses, and the cost per failed delivery. Use carrier exception codes to drive root cause analysis.

Q: Do address-verification tools violate customer privacy?
A: Using third-party validation and carrier services involves transmitting address data. Comply with local privacy laws, disclose processing in your privacy policy and secure appropriate data-processing agreements with vendors.

Q: When should a merchant invest in advanced address tools like geocoding or NCOA?
A: Invest when address-related exceptions materially affect cost or customer experience. High-volume sellers and businesses with significant international shipments benefit earlier. Smaller merchants can start with UX improvements and move up as they scale.

Q: What if a customer disputes a charge because the shipping address was different from the billing address?
A: Keep clear records: stored billing and shipping addresses at the time of purchase, AVS response codes, and carrier tracking with proof of delivery. These data points help resolve disputes and support chargeback defense.

Q: Are there any regions where AVS doesn’t work well?
A: AVS coverage varies. It works best in the U.S., Canada and the U.K., and is less reliable in some other markets. Use regional verification providers where AVS is limited and rely more on carrier validation for deliverability.

Q: How do I handle deliveries to PO Boxes and military addresses?
A: Some carriers cannot deliver certain parcel types to PO Boxes. Flag PO Box entries in checkout and offer alternative delivery partners or pickup options when necessary. For military APO/FPO addresses, ensure customs and carrier documentation meets special requirements.

Q: How do change-of-address services help?
A: NCOA and equivalent services identify recent moves and allow you to refresh saved addresses, reducing shipments to old residences. They are especially useful for subscription services and recurring deliveries.

Q: What role does customer communication play after a suspected address issue?
A: Fast, clear communication saves reshipment costs. If an address is flagged, contact the customer immediately with an easy correction path. Post-purchase confirmation emails that highlight shipping details and provide an edit link for a short window prevent many downstream exceptions.

Q: What’s the best practice for defaulting shipping to the billing address?
A: There is no one-size-fits-all. Defaulting reduces friction for single-address customers but raises risk for gift and multi-address shoppers. Consider leaving the shipping address blank by default or offering a clearly labeled, opt-in “Use billing address” checkbox.

Q: How do parcel lockers and pickup points reduce failed-first-attempt deliveries?
A: They transfer final-mile responsibility from repeated home attempts to a single customer pickup. Lockers are effective in dense urban areas and reduce failed-attempt labor and redelivery costs.

Q: Can machine learning help parse non-standard addresses?
A: Yes. ML models trained on international address patterns can parse free-text addresses and identify anomalies. Pair ML with human review for edge cases to balance accuracy and cost.

Q: Should I require customers to sign for deliveries?
A: Signatures reduce theft risk for high-value orders but increase failed attempts when customers aren’t home. Offer signature-required as an optional service for high-value orders and provide alternatives like lockers or scheduled delivery.

Q: How do I decide which carrier to use for a specific address?
A: Use carrier APIs to assess deliverability and estimated on-time performance for the target address. Rate-shop with delivery-quality indicators and prioritize carriers with better success rates in problematic postal regions.

Q: What immediate step reduces the most address-related problems with minimal cost?
A: Add an order confirmation email that clearly displays shipping details and provides a short edit window. That single change captures many last-minute mistakes and prevents a significant share of misdeliveries.
