Your patron will not see the options for AE, AP, or AA when they enter their billing information. This is because credit card processors have requirements to receive ISO accepted states when processing transactions.  AE, AP, or AA is not within the ISO standard for US so it would not be accepted as valid or show on the payment form. 

To process the transaction successfully, you have two options: 

  1. You can enter the address by entering AE, AP, or AA in the field for City and selecting California as the State.
    Address (Example: PO Box 08) 
    City (FPO AP)
    State (CA), Zip Code
  2. Have the patron use a different billing address.
