Where is authorization number

This can happen when the customer removes their chip card from the reader too soon or when they enter an incorrect PIN.

In these cases, merchants should simply ask the customer to scan their card again and let them know the PIN was rejected if applicable. However, it's obviously not good practice to allow a customer unlimited attempts to enter a correct PIN. A transaction that appears to be a duplicate of an earlier transaction may also receive a temporary decline code.

Other codes can be used to indicate that the card may be lost or stolen, in which case the bank's system may send a code to the merchant asking them to retain possession of the card to prevent further use. Merchants may also be instructed to retain possession of a card in other situations, such as when the bank has no record on file of the card number, which may indicate that a counterfeit card is being used.

Sometimes, the authorization code will instruct the merchant to call the issuing bank on the phone for further instructions. A decline code may also be sent if the cardholder told their bank to allow the transaction only if it equals a certain dollar amount—this is not uncommon with corporate credit cards.

A complete list of decline codes can be found here. In order to avoid authorization-related chargebacks, merchants should never blindly reattempt transactions that have been declined.

If the code indicates that the transaction can be reattempted after certain conditions are met, make sure you understand what the issuer is asking you to do and follow those steps carefully before trying to run the card again.

Remember, a successful authorization code does not mean that the cardholder has approved the transaction, or that they are even aware it is taking place. The code only means that the account has sufficient funds and that the card has not yet been reported lost or stolen.

Using this account, a merchant forwards the details of the buyer's credit card to the credit card network. The credit card network clears the payment and requests authorization in the form of a transaction authorization code from the issuing bank.

On receipt of the code, the merchant concludes the sale process. Each payment system relies on debit or credit card approval codes or "transaction approval codes" to confirm the merchant will receive payment for goods or services sold. When the merchant bank presents the charge to the card holder's bank through the merchant account, the card holder's bank verifies the card holder's account has sufficient funds or credit to "cover" the transaction.

If either is true, the bank transmits an authorization code — a six-digit transaction- and account-specific number — back to the merchant bank, signaling it is OK for the transaction to be approved. If a transaction triggers a request for funds that are not available or an approval of a purchase that exceeds a customer's credit limit, the card holder's bank declines the transaction and does not issue an authorization code.

After the user visits the authorization page, the service shows the user an explanation of the request, including application name, scope, etc. It is important to note that this is not an access token.
