FAQ
Are these credit card numbers real?
No. The generated numbers pass Luhn checksum validation and have correct issuer prefixes, but they are not linked to any real account. They are for testing payment form validation only — they cannot be used for actual transactions.
What is the Luhn algorithm?
The Luhn algorithm is a checksum formula that validates credit card numbers. It works by doubling every second digit from the right, summing all digits, and checking if the total is divisible by 10. All major credit card numbers pass this check.
Can I use these for real purchases?
No. These numbers are mathematically valid but not connected to any bank account or credit line. Any attempt to use them for real transactions will be declined and may be flagged as fraud.
