Credit Card Generator — FAQ
Are these real credit card numbers?
No. All generated numbers are test numbers that pass Luhn validation but are not linked to any real accounts. They are algorithmically generated based on public BIN/IIN ranges and are safe for development and testing purposes.
Is this safe to use?
Yes. All generation happens entirely in your browser using the Web Crypto API. No data is ever sent to any server, no history is stored, and no credentials leave your device.
What is Luhn validation?
The Luhn algorithm (ISO/IEC 7812) is a checksum formula used by all major credit card networks to validate card numbers. It detects single-digit errors and most adjacent digit transpositions.
Can I use these numbers in production?
No. These numbers are intended for development, testing, and QA purposes only. For production, use real card numbers issued by financial institutions.
