In the AVS responses, what does an "A" response indicate?

An "A" response in Address Verification Service (AVS) indicates an exact match on both the street address and the zip code provided during a transaction. This means that the information entered by the customer closely aligns with what is maintained in the relevant database. This level of verification adds a layer of security, helping to reduce fraudulent transactions.

Although partial matches or no matches can occur, those situations would receive different response codes. An "A" response specifically signifies a successful and complete validation of the address details, which is crucial for businesses in assessing the risk of a transaction. An understanding of AVS responses is essential for merchants to make informed decisions about processing transactions, enhancing their fraud prevention strategies.
