Check a credit card number
Luhn Algorithm Check
We will check your phone number based on the Luhn algorithm to see if it is a valid credit card number.
Major Industry Identifier
The first digit of the credit card number represents the category of the entity that issued the card.
Issuer identification number
The first six digits of the card number identify the institution that issued the card to the cardholder.
Personal Account Number
The final number minus 1 (the last one is the checksum), the number 7 represents the personal account identifier.
