Generate dummy cards for payment testing

This credit card number generator creates Luhn-valid dummy card data for developer testing and QA workflows. You can generate multiple card types at once or select a specific network for targeted validation.

The generated card numbers are not real cards. They are not active, are not tied to any person or bank account, and cannot be used for real purchases.

Supported card types

  • Visa
  • Mastercard
  • American Express
  • Troy
  • Discover
  • JCB
  • Diners Club
  • Maestro

How test card generation works

The generator chooses a card network rule, creates random digits that match that network’s length and prefix pattern, then calculates the final Luhn check digit. Expiration dates, CVV/CVC values, and cardholder names are also generated as dummy test data.
