When attempting to complete a purchase through Steam, I receive the following specific error message:

Your purchase has not been completed. Your credit card information has been declined by your credit card company due to an incorrect address being entered.

How can I resolve this issue?

Your purchase has not been completed. Your credit card information has been declined by your credit card company due to an incorrect address being entered.

Failing an Address Verification System (AVS) check

This specific error message indicates the billing information that you have entered has failed a check against the information that your bank or card issuer has on file for this account.

Double check the address information that your bank has on file for this card. Ensure that the street address and zip code match your bank's information exactly and test the issue again. If the issue persists, contact your bank to resolve it.

My bank reports a pending charge for a transaction that appeared with this error

Most banks use light security around this verification system, and will actually accept charges for transactions that fail this check.

Steam has a strict policy that fails all transactions with incorrect, false, or fraudulent address information.

There is no way for Steam Support to force Steam to accept payment from a transaction that has failed in this way, even if the charge still appears as pending in your bank account.

I have entered my billing information correctly, but still see this error

First, ensure that you double-check this information against what your bank has on record. Many online retailers will accept charges from transactions that fail this check, but Steam will not.

In some very rare cases, there may be an issue with the information that your bank checks this information against, or the verification system may be temporarily malfunctioning. If you suspect that this is the case, you may wish to purchase a Steam Wallet card from a physical retailer or use an alternate payment method.
