All billing addresses must be in the US. The billing address you enter must match the address your bank has on file; we send this information to your bank for verification, and we cannot override their response if it does not match. If you feel you are entering your address correctly, please call the 1-800 number on the back of your card, ask for either the Fraud or Authorizations Department and have them verify what your address is on file. If you have more than one address on file (most common with PO Boxes and after moving to a new home) one of those addresses will likely need to be deleted from the bank’s system. Please use the exact address they provide for your billing address.
