Credit card pre-authorization is a banking process in which a merchant temporarily reserves a specific amount of money on a customer’s credit or debit card before completing a transaction. During this process, the payment system verifies that the card is valid and that sufficient funds or credit are available. The reserved amount remains unavailable to the cardholder, but the bank does not transfer the money to the merchant at this stage.
Merchants commonly use pre-authorization when the final payment amount may change or when they need to guarantee payment for a service. Instead of charging the card immediately, the merchant places a temporary hold on the funds. The cardholder cannot use the reserved amount until the transaction is completed or the hold expires.
How Credit Card Pre-Authorization Works
When a merchant initiates a pre-authorization request, the payment processor sends a verification request to the card network and the issuing bank. The bank checks whether the card is valid and whether the account contains sufficient available credit or balance.
If the verification succeeds, the bank places a temporary hold on the requested amount. The funds remain in the cardholder’s account but cannot be spent elsewhere. At this stage, the transaction has not yet been finalized.
After the service is completed or the final amount becomes known, the merchant converts the authorization into a completed payment. At that point, the bank transfers the authorized amount to the merchant and the transaction appears as a finalized charge on the cardholder’s statement.
Common Uses of Pre-Authorization
Businesses often use pre-authorization in industries where the final cost of a service may vary. Hotels frequently reserve funds to cover potential room charges or damages. Car rental companies place holds on cards to guarantee payment for the rental period. Gas stations may also use pre-authorization to verify available funds before allowing a fuel purchase.
Online services and subscription platforms sometimes use small pre-authorization charges to confirm that a card is valid before activating an account.
Benefits for Merchants
Pre-authorization helps merchants reduce financial risk. By confirming that funds are available before providing a service, businesses can minimize the chances of failed payments or fraudulent transactions.
This process also reduces administrative costs associated with payment disputes, chargebacks, and refunds. Merchants gain greater confidence that the customer’s payment method will cover the final transaction.
Impact on Cardholders
For cardholders, a pre-authorization temporarily reduces the available balance or credit limit on their account. Although the bank does not withdraw the funds, the reserved amount remains unavailable for other purchases during the authorization period.
The hold typically remains active until the merchant completes the transaction or cancels the authorization. Depending on the bank and card network, unused authorizations may expire automatically after several days.
Expiration of Authorization Holds
If the merchant does not finalize the transaction, the issuing bank eventually releases the reserved funds. The exact timeframe depends on the bank’s policies and the payment network involved. In most cases, authorization holds expire within a few days, after which the cardholder regains full access to the reserved amount.
Frequently Asked Questions
Does pre-authorization mean the money has been charged?
No. Pre-authorization only reserves funds temporarily. The bank transfers money to the merchant only when the transaction is finalized.
How long does a pre-authorization hold last?
The duration varies depending on the bank and merchant policies, but most holds expire within several days if the merchant does not complete the transaction.
Why do hotels and car rental companies use pre-authorization?
These businesses use pre-authorization to ensure that a customer’s card can cover potential charges such as damages, additional services, or extended rental periods.
Can a pre-authorization be canceled?
Yes. A merchant can cancel the authorization request, after which the issuing bank releases the reserved funds back to the cardholder’s available balance.
