Account Validation (Pre-Authorization) {#recurr-bill-acct-valid}
================================================================

When you capture payment card data for future use, `Cybersource` recommends that you ensure that the account number entered is an active, valid account. You can also use the Address Verification Service (AVS), the Card Verification Number (CVN), and expiration date validation. To validate the account, initiate a zero-amount authorization transaction. To verify that your processor supports zero-amount authorization, see the zero-amount authorization information in the [Payment Services Optional Features Supplement](https://docs.cybersource.com/content/dam/new-documentation/documentation/en/credit-card/supplement/credit-card-services-optional-features-so.pdf "").  
If your processor does not support account validation, you can use the minimal supported amount and do a reversal later. You can also enable the *Data Enrichment for Card Verification* feature, which automatically chooses the minimal authorization amount. Contact customer support for more details.  
For more information about how to perform a pre-authorization, see [*Authorization with Customer Token Creation*](https://developer.cybersource.com/docs/cybs/en-us/tms/developer/ctv/rest/tms/tms-cust-tkn/tms-cust-tkn-create-valid-pay-intro.md "") in the *Token Management Service Developer Guide*.
