Using Address Verification to Reduce Failed Deliveries and Customer Frustrations

Did you know that nearly 20% of deliveries fail on the first attempt? That’s one in every five orders, and for eCommerce brands trying to speed up and reduce the cost of last-mile delivery, that’s more than an inconvenience—it’s wasted resources, frustrated customers, and avoidable costs that chip away at your profitability.

And while you might be quick to blame broken doorbells, tight delivery schedules, and WFO (working from the office), the real culprit is a simple, incorrect address. A missing apartment number, a single typo, or a previous address is costing you fuel, labor, and a second (or third) delivery attempt—assuming the customer hasn’t canceled their order in frustration.

The good news is that address verification tools (also known as an address validation tool) can solve this problem before it even leaves your fulfillment center. Ready to learn more?

The Hidden Costs of Address Errors in Last-Mile Delivery

A single failed delivery costs $17+ on average, and an astounding 5% of all last-mile deliveries fail. When you’re shipping thousands of orders each month, those numbers add up. Fast.

Failed deliveries happen for many reasons. Customers aren’t home, apartment buildings require access codes, and rural addresses are hard to find. But one of the most preventable reasons is an inaccurate or incomplete address entered at checkout.

The immediate consequence is that you have to redeliver. But the hidden costs include:

• A frustrated customer: 84% of customers won’t buy from you again following a bad last-mile delivery experience
• A returned order: The average return rate is already 24.5%. Throw in an order that arrives too late, and you’re doubling your delivery costs and carbon footprint.
• Carrier surcharges: Carriers apply surcharges for failed or corrected deliveries, which quickly add up and negate your profit.
• Carbon footprint: Every redelivery attempt burns more fuel and generates additional emissions, increasing your environmental impact.

Where Delivery Address Errors Happen

Incorrect addresses don’t appear out of thin air. They occur at specific points in the order process, with each one creating a different type of headache for last-mile operations.

At checkout

Everyone’s in a hurry these days, including your customers. They’re typing on their mobiles while commuting to work, fighting with autocorrect while their toddler empties the pantry, or assuming you know the local shorthand for their largely unknown town. Incomplete or inaccurate addresses often slip through your checkout unnoticed and become a problem only when a driver arrives at the destination.

In your order management system

Even a correctly entered address can go haywire during data transfers between systems. An address that worked fine in your eCommerce platform might get truncated when it syncs to your warehouse management system or transportation management system, rendering the clean data unusable.

During label generation

Labels that have been cut off during printing, come loose from the package, or are damaged during transit can turn a perfectly correct address into one that’s incomplete, unreadable, or missing—again, only noticed at the point of delivery.

Common Delivery Address Problems

An incorrect address is nearly always a problem, but there are certain situations where address accuracy and delivery instructions are paramount.

Multi-unit buildings

Apartment complexes, office buildings, and condominiums present unique challenges. A driver might have the correct street address but no suite number, access code, or idea which building the customer lives in. Packages are either returned or left in lobbies, where they’re open to theft.

Rural routes and remote areas

House names instead of numbers, local road names instead of official ones, and incorrect GPS coordinates often lead drivers to the wrong address (or field) in rural areas, leaving them unable to deliver packages within their allotted timeframe.

Gated communities

Gates communities require access codes, names, or arrangements with security guards that aren’t always provided at checkout. If a driver doesn’t know how to gain entry, they can’t deliver the customer’s order.

New construction

Recently developed areas often aren’t in carrier databases or on digital maps yet. The address might be correct, but with no directions, it becomes meaningless.

Each of these scenarios increases the likelihood of a failed first delivery attempt, which burns fuel, adds to vehicle emissions, and frustrates customers who cleared their schedules to receive packages.

How Address Verification Tools Reduce Failed Deliveries

Address verification or validation tools help both you and your customer ensure the delivery address is accurate and the delivery instructions are complete, increasing the chances of a successful first delivery attempt.

The best address verification systems work proactively, catching problems at multiple points before they can derail your last-mile operations, including:

Real-time validation at checkout

Modern address verification tools integrate directly into your checkout flow, suggesting addresses already validated by your carrier’s database as the customer types. The customer can then auto-complete their address, eliminating the risk of typos or incomplete data.

Address standardization

Many carriers have specific formatting requirements for addresses, for example, “Street” instead of “St,” or “Northeast” instead of “NE”. Address verification tools automatically standardize these formats, ensuring your labels meet carrier specifications.

Geocoding

Advanced address verification tools use geocoding to add the exact latitude and longitude coordinates to each address. This helps drivers navigate to the precise location, especially in areas where GPS might struggle. It’s particularly valuable for rural deliveries or new build areas where street addresses might not be as helpful as they should be.

Carrier address verification tool

Most major carriers offer address verification APIs that standardize formats and confirm deliverability. Still, the most effective address validation tools connect to multiple carrier databases, including USPS, UPS, FedEx, and regional carriers. This cross-reference approach catches discrepancies and confirms that your chosen carrier can actually deliver to the address you’re validating. UPS address verification, for example, not only confirms an address exists but also identifies whether it’s residential or commercial, which affects shipping surcharges and service availability.

How to Build Address Verification Into Your Last-Mile Delivery Strategy

Address verification is an ongoing practice you should implement throughout your fulfillment workflow. To start:

• Audit your current address data quality by reviewing your failed delivery rates, return-to-sender rates, and customer complaints about missed deliveries. These metrics reveal where address problems are currently arising.
• Implement address verification at checkout: This is your first opportunity to get clean address data and make the checkout process smoother. It’s also a good idea to add a free-text box for additional delivery instructions, such as access codes.
• Validate addresses in your warehouses: Recheck addresses before printing labels, ideally using a multi-carrier address verification tool.
• Audit your carrier mix: Review which carriers can successfully deliver to specific address types with our carrier market analysis tool.

Conclusion

Failed deliveries will always be part of eCommerce, but with the right address verification tools and processes, you can reduce how often they occur and their impact on your customers and your last-mile delivery success.
