🔍 What is a CC Checker?

A CC checker (credit card checker) is a security research tool used to validate whether a credit card number is active or inactive. Dorkill's CC checker API allows researchers to programmatically test cards against real payment gateways like Stripe, Braintree, and Authorize.net to determine if a card is live or dead.

Unlike basic BIN checkers that only validate card number format, our credit card validator performs real gateway authorization to give you accurate live/dead results with detailed response messages.
