Address verification system
Address verification system (AVS) is an anti-fraud tool used in the UK, US, and Canada for online payments by Visa, Mastercard, and Amex.
The system checks with the bank if the address of the cardholder matches the billing address (provided via the API in the pay-in call). The acquiring bank provides a score as a result of this verification.
Based on the score provided by the bank, Mangopay provides a specific value in the AVSResult
parameter for you to act upon.
AVS Result | Description |
---|---|
FULL_MATCH | The user Address and the address registered on the bank side are exactly the same. |
ADDRESS_MATCH_ONLY | Only the street names are a match (AddressLine1 and AddressLine2 ). Postal codes don’t match. |
POSTAL_CODE_MATCH_ONLY | Only the postal codes are a match (PostalCode ). The street names don’t match. |
NO_MATCH | Both street names and postal codes don’t match. |
NO_CHECK | No check has been done. This may be due to:
This status is also used for 3DS payments until the payment has been validated on the customer side (AVS check given when status = SUCCEEDED) |
Best practice - Implement an AVS result-based payment flow
In order to make the most of this feature:
- Make the user
Address
mandatory in your implementation - Adapt your flow by adding conditions dependent on the AVS result.
One of the ways to use the AVS feature is to rely on the preauthorized pay-in. Steps would be as follows:
- Make a preauthorization
- Check the
AVSResult
Capture the preauthorized funds based on the AVS result
