What is AVS

AVS codes, short for "Address Verification System" codes, are a set of responses generated during credit card or debit card transactions to confirm the accuracy of the billing address provided by the cardholder. These codes help merchants and payment processors assess the validity of the address information provided during a transaction and can be used as part of fraud prevention measures. AVS is commonly used in online and card-not-present transactions to reduce the risk of fraudulent transactions.

Code	Description

P	Partial Match (either address or zip)
U	AVS Unavailable

Explanation of AVS Response Codes:

M (Both address and zip match): This response code indicates that both the provided address and zip code match the information on file. It signifies a successful address verification.
N (Neither address nor zip match): When this code is received, it means that neither the provided address nor the zip code matches the information on file. This could be due to inaccuracies in the provided data.
P (Partial Match - either address or zip): The "P" code is returned when there is a partial match. This means that either the provided address or the zip code matches the information on file, but not both. This is useful in cases where one part of the address is accurate, but the other part is not.
U (AVS Unavailable): If the AVS system is unable to perform the verification for any reason, the response code "U" is used. This could occur due to temporary issues with the AVS service or when AVS is not supported for the given transaction.

These AVS response codes are crucial for assessing the accuracy of address and zip code information provided during transactions. They help in fraud prevention and ensuring that the provided information aligns with the records on file.
