If you run an online business, the struggle with inaccurate addresses is likely all too familiar.
Typos, incomplete information, or even outdated addresses can lead to a cascade of problems – from frustrated customers and delayed deliveries to increased operational costs and potential fraud.
For this reason, e-commerce companies should verify residential and commercial addresses against the postal address database. Address verification software helps businesses validate and standardize shipment addresses. These tools also help banks prevent credit card fraud and shipping companies prepare delivery location geocoding.
Address verification cleans and standardizes address data against an authoritative address database. Address verification software corrects spelling errors, formats information, and adds missing ZIP codes to incomplete or inaccurate physical addresses.
Address verification solutions help companies ensure speedy deliveries, reduce undeliverable mail costs, and make data-driven decisions. Online stores use these solutions to flag fraudulent virtual credit card transactions.
An address verification service (AVS) matches customers' billing addresses with bank records to verify their card ownership. Card processors set up AVS to detect suspicious credit card activity and prevent scammers from using stolen debit or credit cards.
AVS fraud prevention systems alert merchants in case of address mismatches. The merchants then decide whether to process the transaction. Customers receiving an AVS decline must contact the bank to clear pending charges.
AVS initially aimed to help mail-to-order/telephone-to-order (MOTO) transactions but soon became an essential element of card-not-present (CNP) fraud detection systems. Not all credit card providers offer AVS worldwide.
Visa, MasterCard, Discover, and American Express support AVS in the United States, Canada, Australia, New Zealand, and the United Kingdom.
Shoppers in these countries use AVS to keep card information-stealing attacks at bay. Merchants use AVS response signals to prevent chargeback requests.
Address verification systems follow these steps to protect customers and businesses:
| Status | Meaning |
| Full match | Correct street address and ZIP code |
| No match | Incorrect address |
| Partial match (ZIP code) | Correct ZIP code |
| Partial match (address) | Correct street address |
| Unavailable | Unresponsive AVS processor |
| International | Foreign address formats |
| Unavailable | No information |
| Retry | Server error |
Address validation checks a postal address against a database to determine whether it’s a deliverable address. Address validation tools typically use authoritative databases such as the United States Postal Service (USPS) or Canada Post to run these comparisons.
Address verification parses, matches, formats, transliterates, and enhances address lists to ensure accuracy. Some software solutions use delivery point validation (DPV) or Coding Accuracy Support System (CASS) certified address lookup engines or global reference databases to check how accurate and complete an address is.
The main difference is that address validation solutions validate addresses and check deliverability, whereas address verification enhances address data for accuracy.
Customer-facing businesses collate multiple geographic and demographic databases. Customer data isn’t always accurate because of human errors like typos and missing numbers. If that isn’t enough, more than 130 address formats exist around the world.
Nowadays, businesses use address verification systems to resolve customer address data and correct inaccuracies. Business owners validate physical addresses across mailing lists, spreadsheets, customer databases, customer relationship management (CRM) solutions, and enterprise resource planning (ERP) systems.
Address verification solutions make retailers' lives easier in many ways. Here are a few improvements that AVS provides.
Punctual delivery boosts sales and improves customer satisfaction, while failed delivery causes high customer attrition and affects annual revenue. That’s why e-commerce companies go to great lengths to get the correct addresses.
Companies use unobtrusive application programming interface (API) integrations to automate data entry, reduce keystrokes, and streamline the checkout process.
Not having the correct address increases shipping expenses. Failed deliveries also obviously increase shipping costs, but there’s more to it than that.
Residential address deliveries cost more than commercial ones. Large retailers use accurate customer address databases to identify geographic buying habits and plan warehouse management accordingly to deal with this problem.
Third-party logistics providers like FedEx or United Parcel Service (UPS) charge address correction fees when original ship-to addresses don’t match their database data or format.
When businesses don't validate delivery addresses at checkout, they’re more likely to overlook errors and end up paying these fees. Address verification software systems help companies identify and address mistakes and minimize correction charges.
Address verification also limits credit card fraud and chargebacks. Merchants use address verification tools to verify cardholder addresses, authenticate CNP transactions, and minimize chargebacks.
Sharing economy businesses and ride-sharing software providers leverage address verification software to meet know-your-customer (KYC) requirements and establish trust.
Retail chains customize products and mail promotional materials frequently. They typically use internet protocol (IP) addresses to filter customer locations. However, IP addresses only offer ZIP codes and aren’t always reliable.
Moreover, some users hide their IP addresses with virtual private network (VPN) software to prevent traceability. In these cases, address verification solutions narrow down valid addresses to help direct marketing efforts.
Average checkout pages require customers to fill seemingly endless form fields manually. Customers often don’t like this lengthy checkout journey and abandon carts.

One way to address this problem is to leverage intelligent address auto-completion. Smart address validators capture data from minimum inputs and suggest addresses. Customers pick the correct suggestions and proceed to payment.
User experience (UX) can make or break e-commerce businesses. Customers want a frictionless checkout experience, and stores want to streamline the order fulfillment process by validating users' addresses.
The right address verification tool with design and microcopy kills two birds with one stone. Below are the four types of address capture verification tools that businesses use.
Imagine a software combining your customer data and delivering accurate, fit-for-purpose data – that’s what an address verification software does.
It verifies the numeric part of an address against a standard postal service address database. Some solutions also offer real-time validation using address verification API.
First, a customer keys in debit or credit card data during a transaction. The credit card processor or issuer compares the billing address with the address on bank records.
The address verification system sends a one-digit code to the retailer depending on the similarity between these two addresses. Merchants interpret this code to decide whether to accept or reject the transaction.
Address verification programs use different address-matching algorithms to return verification codes. Below are some of the most common methods that verifiers use.
Customer databases typically return too few or too many results for a query. Businesses can’t sit throughout the day to correct or deduplicate them manually. They use fuzzy address searching to find potential matches for an address.
Fuzzy matching, or approximate string matching, is an intelligent application. It returns all potential records instead of flagging a record as a match or non-match. This algorithm looks at a word’s uniqueness to correct other elements. Natural language processing (NLP) also plays a crucial role in identifying and correcting typos in real time.
Data quality software uses fuzzy matching to correct phonetic address misspellings and reformat numeric elements. Spell checkers inside document creation software use fuzzy matching to recognize word patterns, find a word match in the database, and generate alternatives.
Businesses use address data visualization to optimize distribution channels and streamline logistics. For example, retailers can fetch customers’ actual locations and serve them better using location intelligence software. Geocoding offers location insights and helps companies tailor services accordingly.
Geocoding or address geocoding converts an address description into a pair of geographic coordinates. This address verification method helps businesses locate an address on the Earth’s surface. Using geographic information system (GIS) software, geocoding displays locations spatially and enables you to analyze data and recognize patterns.
Reverse geocoding translates latitude and longitude coordinates into human-readable addresses. This method interprets coordinates into data to help businesses make data-driven decisions.
Geocoding and reverse geocoding processes offer different accuracy levels depending on their algorithms.
| Geocoding type | Offers | Accuracy level |
| Parcel centroid geocoding | locates the center of a property | Medium |
| Thoroughfare geocoding | returns one or more nearby locations | Medium |
| Administrative geocoding | connects an area to a state or province | Low |
| Rooftop geocoding | pinpoints exact coordinates based on multiple sources | High |
Address standardization or address normalization checks, corrects, formats, and deduplicates address records to meet national postal standards.
Businesses use address standardization to resolve the following information issues:
Businesses also experience address changes due to rapid urban development and new construction. Address standardization helps them add accurate delivery network addresses and share store pickup information.
Many businesses across domains regularly need to check whether an address is deliverable or not. Take a look at these common address verification applications to understand whether an address verification tool is helpful for your business.
Regardless of their size, businesses collect address information from marketplaces, checkout systems, customer profiles, and third parties. The right address verification software helps companies standardize data and format it correctly with DPV.
Follow these five best practices to make the most out of residential and commercial address verification software.
Address verification streamlines business operations. Companies lose money because of inaccurate and outdated data, while the right address verification software ensures a smooth connection with customers.
Below are the features that businesses should look for in an address verification solution.
High-quality data is one of the most important factors to consider when choosing an address verification vendor. Top software solutions use proprietary frameworks to cleanse and validate data against multiple third-party systems, country-specific restrictions, and structures.
These providers also geo-locate and repair data as per client needs. With high-quality data, businesses increase operational efficiency, effectively communicate with customers, and drive return on investment (ROI).
Address verification integration capabilities improve data quality across systems. That’s why it’s best to look for software solutions that work with your existing CRM or ERP systems.
Advanced integrations help you capture accurate data at the entry point, eliminate redundancies, and maintain data accuracy throughout databases.
Companies also need to look into a vendor’s data security measurements before opting for an address verification tool.
A software provider's privacy and security policy tells you how they store, treat, and use your data. You can also sign a non-disclosure agreement (NDA) so a vendor maintains their privacy commitments and protects your data.
The right address verification software helps you cut costs, maintain compliance, and effortlessly connect with customers. These top software solutions are ideal for fixing poor-quality addresses, securing data set accuracy, and boosting operational efficiency.
