You: If you received the remittance advice via email, use the 6-digit card account prefix (556766) and merge it with the Comdata MasterCard account number provided in the email remittance to process the payment through your credit card system. Alternatively, the Remittance Advice contains a CTX 820 file, which you can download and upload to your accounting system to process the payment.

If the remittance was received via U.S. mail, simply process the account number provided through your credit card system as you would any other credit card payment.
