Like a lot of RC sites that use authorize.net for credit card transactions many customers are unable to purchase through the conventional methods because of your credit card transfer issuer (authorize.net)
All transactions put through authorize.net where the issuing bank does participate in AVS end up declined because authorize.net sees their zip code as malformed
The Address Verification System (AVS) is a system used to verify the identity of the person claiming to own the credit card. The system will check the billing address of the credit card provided by the user with the address on file at the credit card company. The other security features for the credit card include the CVV2 number.
If the bank doesn't support AVS, its treated as AVS unavailable and is accepted.
If the bank does support AVS, its treated as AVS MISMATCH and is declined, even though it is right.
At present, only a few countries support AVS on Visa and MasterCard, notably the USA, Canada and the United Kingdom. American Express does not support AVS in other countries than the USA.
Cardholders with a bank that does not support AVS may receive an error from Internet stores due to the lack of data.
