Address Verification System (AVS) Filters

Merchant administrators have the ability to set up filters for the Address Verification Service when logged into RPM.  Filters are set out the outlet (terminal) level.  For instructions on how to set up the filters, click here.

When setting up AVS you can choose to setup your system to have a positive or negative match. AVS works on a system of inclusion or exclusion. The AVS result should be treated as an indicator of whether or not to accept the authorization that was provided. This determination is to be made by the merchant. You either choose to approve or reject transactions with specific AVS Codes. Most clients like to approve all transactions except in case of N (which equals No match).

Merchants who do not provide address information in their transactions may be subject to additional fees imposed by their acquiring institution or bank.

Address Verification String # is a number that is part of the AVS system. As a means of detecting fraudulent transactions, AVS matches the address sent with the transaction to the actual billing address of the cardholder. When address verification is requested, the field will contain the mailing address on the cardholder's monthly statement. The address field cannot exceed 28 characters in length and the zip field cannot exceed 10. The Address is provided in the “VerificationStr1” field and must be formatted as follows:

Street Address|Zip/Postal|City|State/Prov|Country

Note that the pipe character, |, is used to separate the different pieces of information.

example:
1391 ELM STREET|40404
or P.O. BOX 24356|55555

If any of the address fields are not available or not applicable, they may be omitted. If available, the last 5 or 9 digits, without embedded spaces, should be the zip code (ex. "12345-6789" becomes "123456789"). Numbers are not spelled out. (“First Street” becomes “1ST Street”, “Second” becomes “2ND”, etc).

For instance:
1391 ELM STREET 40404
is equivalent to: 1391 ELM STREET|40404

IMPORTANT: This information is provided to First Data Payeezy Gateway in property: VerificationStr1.

Property: VerificationStr2 is to support future verification strings being deployed by Visa and other
credit card companies. (i.e. EVV2).

The AVS result is a one character response that indicates the “degree” of match for the provided
address. Currently supported AVS responses are found in the AVS Response Codes table.
