# Charge succeeded despite CVC or ZIP check mismatch

This can happen when a customer's bank approves the charge despite the CVC or ZIP code mismatch.
You can use [Radar's](https://stripe.com/radar) [built-in rule](https://stripe.com/docs/radar/rules#traditional-bank-checks) to block charges that fail the CVC or ZIP code (AVS) check.
## Additional Information
* Without a specific block rule in place, a charge can still be approved by the customer’s bank, even if the CVC or ZIP code (AVS) check fails. Banks take a variety of signals into account in their own systems and may see a charge as being legitimate despite the check not passing, and then send the charge approval along to Stripe.
