What is a Credit Card Validator?
A credit card validator is a tool that checks if a credit card number follows a valid format and passes the Luhn algorithm check, which is used by virtually all credit card issuers to identify valid card numbers.
Our validator also provides detailed information about the card by analyzing the BIN (Bank Identification Number), which is the first 6 digits of the card number. This information includes the issuing bank, card brand, card type, and country of issuance.
Important Note: While this tool can verify if a card number is properly formatted and potentially valid, it does not check if the card is active, has available funds, or if it has been reported stolen. This tool is intended for educational and verification purposes only.
How Does a Credit Card Validator Work?
Credit card validation works by analyzing the card number's structure and applying the Luhn algorithm (also known as the "modulus 10" algorithm), which is used worldwide by card issuers to distinguish valid numbers from mistyped or otherwise incorrect numbers.
The Luhn algorithm works by calculating a checksum of the digits in the card number. If the checksum is divisible by 10, the number is considered valid. Additionally, our validator checks the card's BIN (Bank Identification Number) against our database to provide information about the card issuer and type.
