What is AVS & AVS mismatch? How address verification keeps your transactions secure 



Address Verification Service (AVS) is the process of verifying the accuracy and validity of a physical mailing address. Individuals or businesses provide these physical addresses to e-commerce companies or banks. Companies and organizations that use AVS ensure that the addresses provided by their customer or clients are valid and match the information on file.

AVS usually uses a database of valid addresses to determine if the provided address matches the information associated with the client or customer. The verification process involves checking the street name, building number, city, state, and ZIP code against the database. Additionally, some AVS solutions offer address format correction, identifying missing or incorrect elements, and standardizing the address for consistency. These additional features help maintain a clean database and avoid any inconsistency that may cause issues and errors. AVS can integrate into online forms, point-of-sale systems, customer databases, and other applications to automatically validate addresses in real-time or batch.

So, why is address verification essential, and what impact does AVS have across various industries? The primary goal of AVS is to improve data quality, reduce errors, and enhance the customer’s experience. The service accomplishes these goals by ensuring accurate addresses in various business operations. An AVS should have a high accuracy level that prevents shipping errors, reduces the risk of fraud or identity theft, improves mail delivery efficiency, and ensures compliance with regulations and requirements related to address validation. These factors create a quality customer or client experience.

Now that we understand what AVS is and the impact that it has, let’s delve into the purpose and benefits of AVS. We’ll also explain what AVS mismatch is, how to address this challenge and explore the future of AVS.

By simplifying the checkout process, you’re eliminating any barriers to purchase and, at the same time, protecting your business by verifying the customer making the purchase.

Fraud is one of the most significant issues facing businesses and organizations conducting online transactions. AVS plays a crucial role in fraud prevention by comparing the address provided by the customer to the billing address on the credit card used for payment. If the addresses do not match, it raises a red flag for further investigation. By detecting potential fraud, AVS helps protect customers and businesses from unauthorized transactions and identity theft.

The prevalence and demand for online shopping demonstrate the necessity for fast and efficient delivery to maintain and build a successful e-commerce brand. AVS assists in improved delivery and ensures that packages are delivered accurately and promptly for businesses involved in shipping and logistics. Postal address verification helps carriers navigate efficiently, reducing the chances of lost or delayed shipments. This verification results in a positive customer delivery experience, with timely and accurate receipt of their orders.

With accurate address information, businesses can personalize and customize their customer communications. Whether sending targeted promotions, personalized mailers, or tailored services based on location, AVS enables businesses to provide a more personalized and relevant customer experience.

In specific industries like finance and healthcare, stringent regulations govern address validation and customer data accuracy. AVS assists businesses in complying with these regulations, lowering the risk of penalties and legal issues. Businesses build trust and improve customer experience by committing to data accuracy and security.

The benefits of a trusted AVS provider are critical to healthy online businesses, especially if you’re in a sector that regularly uses addresses.That said, no system is perfect. Let’s discuss specific challenges with these programs and solutions to those challenges further.

AVS Mismatch: Challenges and Issues

AVS mismatch occurs when the information provided during address verification does not match the data in the AVS database or does not meet the required validation criteria. This mismatch can happen for various reasons, including inaccurate address data, differences in address formats, or issues with integration and implementation.

There are various challenges associated with AVS mismatch. Let’s explore some commonly occurring issues.

  • Inaccurate or outdated address data: AVS relies on accurate and up-to-date address databases. However, if the database is incomplete or contains outdated information, it can result in mismatches and validation errors. Common address data issues include misspellings, incomplete addresses, or outdated postal codes. When the database has errors, it cannot accurately match customers to the correct address and causes challenges for both customer and provider.
  • Complex and changing addresses: Address formats vary across regions, countries, and even different postal systems. AVS systems need help accurately validating addresses that deviate from standard formats or include non-standard elements. Addresses with unique local identifiers or unconventional building numbering systems often present challenges for some AVS verification systems.
  • International addresses: These often pose additional complexities due to variations in address formats, languages, and postal code systems. AVS systems must account for these differences and have comprehensive international address databases to verify addresses worldwide accurately.
  • Integration and implementation issues: Integrating AVS systems into existing business processes and software can be challenging, depending on your chosen AVS provider. Compatibility problems, data mapping errors, or limited system resources pose issues during implementation. These technical hurdles sometimes lead to AVS mismatches and hinder the smooth operation of the address verification process.
  • Data quality and maintenance: Regularly updating address databases ensures the quality of the data. Failure to update or cleanse the database can lead to mismatches compared to the most recent address information. It is critical to have good data management practices in place to maintain the accuracy and integrity of the AVS database.
  • False positives and false negatives: AVS systems may produce false positives, in which a legitimate address is mistakenly flagged as invalid, or false negatives, in which an invalid or incorrect address is mistakenly validated. These mistakes can disrupt customer experiences, cause delays in transactions or deliveries, and impact business operations.
  • Integration with multiple systems: Many organizations operate across multiple systems or platforms. Such complexities can cause challenges when integrating AVS across various applications. Ensuring consistent address verification across all systems is complex and requires effective coordination and synchronization.
  • Address change management: When customers relocate or change addresses, updating and keeping accurate address information is critical. Managing address changes and ensuring a smooth transition within the AVS system can be difficult, particularly for businesses with a large customer base.

Addressing the AVS Mismatch


With all the AVS mismatch issues, what are the solutions since AVS is such a critical aspect of e-commerce and other online programs? There are multiple options for addressing and managing AVS mismatch.

  • Data quality management: Done properly, this ensures the accuracy and completeness of your address database by regularly updating and cleansing the address data to eliminate outdated or incorrect information. Implement data quality measures such as validation rules, data deduplication, and address standardization to improve the overall quality of your address data.
  • Standardized address formats: This practice guarantees consistency and compatibility across various systems and databases. Standardizing these formats adheres to industry-standard address formats and incorporates them into your AVS system. This formatting reduces discrepancies between the provided address and the expected format for validation.
  • Address APIs: APIs that connect with the AVS provider’s database in real-time allow businesses to validate addresses during data entry or transaction processes. This real-time verification ensures immediate feedback on the validity of the address and reduces the chances of mismatches.
  • Manual review: To further avoid mismatch, it is imperative to monitor and analyze the performance of your AVS system continuously. Track the frequency and nature of AVS mismatches to identify patterns and potential issues. Analyze the root causes of mismatches and take corrective actions to improve the accuracy of address validation.
  • Feedback and iterative improvements: These are necessary to maintain your AVS system and avoid mismatches. Gather feedback from users, customers, and internal stakeholders regarding their experience with the AVS system. Use this feedback to make iterative improvements, address specific pain points, and resolve recurring AVS mismatch issues. Actively seek user input to refine the address verification process.

AVS mismatch is challenging for all businesses and organizations using and needing AVS. By properly understanding and approaching the issue, it’s possible to mitigate these mismatches.
