Telephone Authorization (U.S. Merchants)

On rare occasions, approval for a credit card payment may need to be obtained from the card processor (Visa, MasterCard, Avcard, etc.) by telephone. This telephone approval (voice authorization) could occur in the following circumstances:

  • Card has been declined online and customer requests that you attempt approval by telephone 
  • Internet connection problems delay online authorization and processing

The card processor will provide an approval code. The code should be entered in the Telephone Authorization Code field on the Authorize Online Payment screen. Entering a valid code will bypass the standard online authorization checks so processing of the payment may continue. The transaction MUST be processed correctly through your FBO One system in order for the charge to be paid. Simply getting an approval by telephone does NOT get you the money. Authorization codes obtained by telephone are only valid for a limited amount of time, so do not delay in using the code.

If a Telephone Authorization Code is used for an AIR Card transaction, a later void or refund/credit of the transaction is not possible online, so please verify that the transaction is correct before processing. If a void or refund/credit is needed, please contact AIR Card Merchant Support for assistance:
