Credit Card Transactions
Processing Platforms Supporting Address Verification Service
Address verification service compares the submitted billing street address and ZIP code with
the values on file at the cardholder’s bank. The response includes values for AVSADDR and
AVSZIP: Y, N, or X for the match status of the customer’s street address and ZIP code.
Y = match, N =nomatch, X = cardholder’s bank does not support address verification service.
The address verification service result is for advice only. Banks do not decline transactions
based on the address verification service result—the merchant makes the decision to approve
or decline a transaction. Address verification service is supported by most US banks and some
international banks.
N OTE: Address verification service checks only for a street number match, not a street name
match, so 123 Main Street returns the same response as 123 Elm Street.
The international address verification service (IAVS) response indicates whether address
verification service response is international (Y), USA (N), or cannot be determined (X).
