What is an AVS Test?

The Address Verification System (AVS) test is a security measure used by financial institutions to verify the accuracy of the billing address provided by a customer during a transaction. This test is an essential part of the credit card verification process and helps prevent fraudulent activities.

How Does the AVS Test Work?

When a customer enters their billing address while making a purchase, the AVS test compares the address with the one on file with the credit card issuer. The test checks the street address and the zip code for a match. If both pieces of information match, the transaction is considered to have passed the AVS test.

Why is the AVS Test Important?

The AVS test is crucial for several reasons:

  • It helps in reducing the risk of fraud by ensuring that the customer's billing address is correct.

  • It provides an additional layer of security for both the merchant and the customer.

  • It can help prevent chargebacks due to billing address discrepancies.

Types of AVS Responses

The AVS test provides various response codes that indicate the level of match between the billing address and the one on file with the issuer. Some common response codes include:

  • Code M: The address matches exactly.

  • Code N: The address does not match.

  • Code X: The address information is missing.

  • Code Z: The address information is invalid.
