What it is

The approval code assigned by the issuer (or stand-in) for an approved transaction — printed on the receipt.

Specification reference

Defined in ISO 8583:1987 (base). Card networks publish their own dialect tables (Visa BASE I / V.I.P., Mastercard CIS) that refine formats, lengths, and — for private-use elements — the entire layout. Always confirm against the interface specification you implement.
