Address Verification System (AVS)
When entering your payment information, make sure to enter your billing address exactly as it appears on your account statements. Everything - including hyphenation and spacing - must exactly match the information that the issuing bank has on record in order to pass the AVS check.
Note: If your transaction fails to pass this check, your credit card issuer may place a temporary hold on the funds for the attempted purchase (this hold may last several days, depending upon their policies).
