The Edge required numbering specification is Interleaved 2 of 5, which starts with a unique four-digit assigned prefix based on the store account and card type and ends with a check digit, which is a calculated number to ensure validity.

Each card has a printed number and a barcode number, which also has a numerical representation.  Either number can be used for entering or scanning the card.
