Limited Acquirer Support

AVS checks are currently only supported by a limited number of acquirers. If the AVS fields are used where support is not yet available, the transactions will process as normal and return an avs_result_code of 101 which indicates that AVS is not supported.

AVS (Address Verirfication System) is a service that combats fraudulent activity by verifying a cardholder's address information against the card issuer's records.

AVS is currently supported by Fat Zebra on Purchases via the billing_address field. If this field is specified, the Fat Zebra API will return an avs_result_code field indicating the result of the AVS check.

The following avs_result_code values may be returned:
