How Address Verification Fraud Prevention Protects Your Business
Fraudsters are becoming sophisticated in exploiting vulnerabilities, especially in payment systems. One of the most common methods they use to commit fraud is manipulating shipping and billing addresses used by the customers. It can often go undetected if businesses don’t have the proper address verification solution in place. According to IC3, Identity theft was among the top reported crime types, involving fraudulent use of personal information, including addresses.
In this blog, we will cover how criminals are altering address information for illegal transactions. We will also tell you how to choose the right address verification solution and the best practices for maximizing its benefits.
Key Takeaways
- Fraudsters are becoming clever in how they are conducting address-related fraud. They make small changes to the street name and building number, which often go unnoticed.
- AVS compares the address entered by the customer with official postal records and identifies mismatches or partial matches. It blocks the transaction and stops fraud before it can occur.
- When selecting an AVS, businesses should look for global coverage, real-time verification capabilities, and a scalable system that can handle increasing transaction volumes.
How Fraudsters Manipulate Address Information to Conduct Fraudulent Activities
Altering the Billing Address
Fraudsters may alter a portion of the billing address, such as the numeric portion in the street number, or slightly change the street name. Take, for instance, they will change “123 Main St.” to “1234 Main St.” It will bypass a system that doesn’t have robust address-matching rules. They may also use a vacant building, a random address from a postal code, or an incomplete address that appears plausible. This trick works if the system doesn't flag incomplete or invalid addresses.
Exploiting Address Variation Across Systems
Different internal system processes address differently. This leads to inconsistencies that fraudsters can exploit. Miscreants may change minor details in the address to fit the format that a particular platform accepts. Take, for instance, they might be substituting “Rd” for “Road.” Since the details will pass through multiple systems with varying formatting rules, they may appear valid even if they are not legitimate.
Account Compromise
Criminals may gain unauthorized access to a customer’s account either through phishing, stolen credit card information, or data breaches. Once inside, they can change the saved billing or shipping address to redirect goods to an address they control. Since this system will see that the purchase is being made from a recognized account, it will not raise any flags.

What Is an Address Verification Solution (AVS)?
It is one of the most useful fraud detection tools that businesses use to validate the provided address in an online transaction. AVS functions by comparing the information with the official postal records of the nation. If they do not match, it will raise an issue with the business, indicating there have been fraud attempts.
The AVS response code shows the degree of match by the following methods:
- Full Match: The address entered by the customer matches exactly with postal entries in the USPS or NCOA. The transaction is valid and is safe for processing.
- Partial Match: Only some part of the address matches. For example, it could be the correct street address, but the zip code won't match. Depending on the merchant's fraud policy, the transaction may be flagged for review or rejection by the system.
- No Match: This AVS code means that the address provided by a customer does not match any in the database. It may be a sign of possible fraud. The system can reject the transaction or verify it manually.
Role of AVS in Fraud Detection and Prevention
Early Detection of Suspicious Activity
If the billing address provided by the customer does not match the postal database, the AVS will return a response that alerts the merchant of a mismatch. Businesses can flag the transaction as suspicious before processing.
It can also help businesses monitor unusual patterns in customer behavior. It can be a high volume of orders from the same address formats or address and zip code combinations that don’t match the usual customer base. These anomalies can be signs of fraud and can prompt further investigation.
Early detection allows businesses to take proactive steps before shipping the product and processing the payment information. It significantly reduces the likelihood of financial losses.
Minimizing Chargeback Risk
When a customer disputes a charge or requests a refund due to an unauthorized transaction, chargebacks take place. AVS will check the address provided during checkout, and if there is a mismatch, it will flag it. It will ensure the details match the address on file of the USPS or NCOA. Businesses can reduce fraud and chargebacks that arise from transactions made with stolen payment information.
Additionally, AVS is an important solution for credit card transactions. By confirming the billing address of the cardholder, it will prevent credit card fraud and minimize the chances of chargebacks due to fraudulent transactions. However, AVS is most effective when combined with a broader chargeback fraud prevention strategy, as not all fraudulent disputes involve billing address mismatches. Monitoring behavioral signals and transaction patterns can help identify suspicious activity that AVS alone may not detect.
Serves as an Identity Verification Tool
It compares the billing details with the address database of the postal services to ensure that the person is a legitimate account holder. Businesses can process the transaction with confidence and prevent the possibility of identity theft.
