# AVS responses for point of sale

Address verification system (AVS) responses for Mail Order/Telephone Order payments.

[View source](/point-of-sale/mail-and-telephone-order-moto/avs-responses-pos.md)

For risk management purposes, you can add an Address Verification System (AVS) check to [Mail Order/Telephone Order (MOTO)](/point-of-sale/mail-and-telephone-order-moto) payments. The payment terminal then prompts you to enter the shopper's postal code (zip code) and house number. The card issuer validates the data you entered and returns a response that can help you decide whether to go ahead with the transaction or cancel the authorization.

We map the AVS responses we receive from card issuers to the following AVS results that can appear in your payment response, in the `avsResult` element of the `AdditionalResponse`. When we do not receive a response from the issuing bank, the AVS result is "Unknown".

## Requirements

Before you begin, take into account the following requirements and limitations.
