Frequently asked questions about Test Credit Card Generator

Can these cards be charged?

No. They use documented test BIN ranges (4111 11…, 5555 55…, 3714 49…, 6011 11…, 3530 11…) and are only accepted by sandbox gateways; they carry no funds.

Do the numbers pass the Luhn check?

Yes, every generated number is Luhn-valid unless you enable "Luhn-invalid numbers" for negative tests, in which case every fourth row fails and is flagged.

What is the Mada-style option?

A 16-digit number starting with 4 in a sandbox prefix, shaped like a Saudi mada card for local payment-form tests. It is not issued by any bank.

Which brands and lengths are covered?

Visa (16), Mastercard (16), American Express (15, 4-digit CVV), Discover (16), JCB (16), Diners Club (14), UnionPay (16) and Mada-style (16), each with expiry and CVV.

Technical notes

The Luhn check digit is computed by doubling every second digit from the right, subtracting 9 from results above 9 and choosing the digit that makes the total divisible by 10. Because the BINs come from published test ranges, issuers will decline any real transaction.
