Frequently Asked Questions
What is the Luhn algorithm?
The Luhn algorithm (or Modulus 10) is a checksum formula used to validate credit card numbers, IMEI and other identifiers. It verifies whether the numeric sequence is mathematically valid, preventing typos.
Which card brands are supported?
We support 7 brands: Visa, Mastercard, American Express (Amex), Elo, Discover, Diners Club and Hipercard. Each uses specific IIN/BIN prefixes and different lengths.
Can the generated numbers be used for purchases?
No! The numbers are mathematically valid by the Luhn algorithm, but are NOT linked to any real bank account. They are exclusively for testing form validations, payment gateways and e-commerce systems.
Is it safe to use this tool?
Yes. All processing is done locally in your browser. No numbers are stored or sent to servers. The tool is 100% client-side.
What are test card numbers used for?
Developers use them to test form validations, payment gateway integration (Stripe, PagSeguro, etc.), e-commerce checkout flows and automated software testing.
