What is the Credit Card Generator?
The Credit Card Generator is a free online tool that creates structurally valid test credit card numbers. Each generated number passes Luhn validation and comes with a random expiry date and CVV — ready to paste into any payment sandbox or test environment.
How to use it
Select a card network (Visa, Mastercard, Amex or Discover), choose how many numbers you need, and hit Generate. Each row shows the card number, expiry and CVV. Click the copy icon on any row to grab it, or use Copy All to get everything at once.
Use cases
Payment gateway integration testing — verify your checkout flow handles different card brands correctly. Staging environment seeding — populate test accounts with realistic-looking card data. E2E test automation — feed generated numbers into Cypress, Playwright or Selenium scripts. QA regression suites — ensure payment forms validate, mask and format card numbers as expected.
Is this data real?
No. Every number is entirely synthetic. They pass Luhn checks so payment forms accept them, but they are not linked to any real account and cannot be used for actual transactions. This tool is strictly for development and testing.
