In the first of a three-part series on combating fraud, we look at the address verification system (AVS). AVS assists in the authentication of a shopper claiming to own a credit card. It compares the shopper’s billing with the address(es) on file with the card company. AVS is not an exact science, however, because it only checks the numeric portions of a cardholders billing address.
Consider the following US billing address:
2495 Truxtun Rd,
San Diego, CA 92106
The AVS system will see it as 2495 for the address numeric, and 92106 for the zip code.
Taking another example:
2495 Rosecrans St,
San Diego, CA 92106
It will be read as 2495 for the address numeric and 92106 for the zip code.
As far as AVS is concerned, both addresses are the same! Normally, if the AVS check returns a negative result, the transaction will be declined. However, declines can result from common and legitimate issues. For example, a card holder may have moved address and not updated the details on file with the issuer.
Flexible AVS Options with NitroSell eCommerce
Techniques to combat fraud should be employed by every retailer and, where possible, we will continue to implement anti-fraud techniques in our payment gateway integrations. With AVS, NitroSell eCommerce provides you with as much information as possible, helping to minimize false positives and empower you to make informed decisions about fraud.
When configuring your payment gateway in the WebStore Manager, the following options are available:
- Perform AVS Check: notification service only. In the event of a negative result, the transaction will be permitted and the accompanying result notice will be presented to you in RMS during order fulfilment;
- Use Strict AVS Check: block transactions if AVS fails. An AVS check will return a different AVS code depending on the result. With this option enabled, a transaction will pass only if the AVS check returns a code that satisfies the standard list of safe AVS codes.
