Check whether a card number passes the Luhn checksum and see which network it belongs to. Useful for testing payment forms with test numbers.
Card numbers include a final check digit. The Luhn algorithm uses it to catch typing mistakes without contacting the bank. Payment forms often run this check before sending a number for authorisation.
This tool runs the Luhn check and identifies the card network from the number's prefix and length. It is meant for testing with test card numbers.
No. It only means the digits are consistent. It says nothing about whether an account exists or has funds.
No. Use test numbers such as the ones payment providers publish. Nothing is sent anywhere, but there is no reason to type a real number.
The prefix and length do not match one of the supported networks.
IMEI numbers and many national ID and account numbers.
