Transaction Lifecycle, Funding, and Reconciliation
Authorization Response Codes Guide
Understanding authorization response codes is essential for merchants and payment professionals to effectively manage transaction lifecycles, funding, and reconciliation. These codes indicate whether a payment authorization request was approved, declined, or requires further action. Early recognition of these codes helps in troubleshooting payment issues and optimizing processing workflows.
What Are Authorization Response Codes?
Authorization response codes are numeric or alphanumeric values returned by the card issuer or payment processor after a transaction authorization attempt. They provide a standardized way to communicate the status of a payment request, such as approval, decline, or error. Familiarity with these codes allows merchants to quickly identify the reason behind a transaction's outcome.
Common Authorization Response Codes
- 00 – Approved: The transaction was authorized successfully.
- 05 – Do Not Honor: The issuer declined the transaction without specifying a reason.
- 51 – Insufficient Funds: The cardholder’s account lacks sufficient funds.
- 54 – Expired Card: The card used has expired.
- 91 – Issuer or Switch Inoperative: Temporary communication failure with the issuer.
Knowing these codes helps merchants decide whether to retry a transaction, request an alternate payment method, or contact the customer for more information. It also aids in reconciliation and dispute resolution by providing clear transaction status details.
