Simulating AVS Responses

By default, all transactions will have an AVS response of "MATCH" (address information matches). In order to simulate a different response, add a single prefix code from the table below in front of the value you include for the street parameter.

Prefix

AVS Code Description
10 MATCH Both the address and zip code match
11, 16 MATCH_ADDRESS_ONLY

Address matches, but zip code does not

12, 17 MATCH_ZIP_ONLY Zip code matches, but address does not
13 NO_MATCH No part of the address matches
18 NOT_PROCESSED Address information is unavailable
15 UNKNOWN Unknown response from issuer/bank
