Far from being a random combination of digits, credit card numbers follow a strict logic that needs to verify against the “Luhn formula” to be considered valid. Easy Credit Card Checker can tell you if a credit card number is valid or not in just one click, verifying its validity by applying the LUHN10 algorithm to it. It works with all the most widely used credit card types and some defunct ones.

All you have to do is input a credit card number and click on the “Check” button to know if the card number you’ve been given is acceptable or not. This quick and extremely easy-to-use tool is excellent for a small or medium business that requires verifying credit card numbers that have been provided via the phone, e-mail, etc. Using the first one or two digits, this small utility will first recognize the type of card you’re trying to check (4 for Visa, 5 for MasterCard, 34 or 37 for AMEX, etc.), and will then apply the Luhn formula to the entire number to make sure that the result is divisible by 10. If it isn’t, the program will display an “Invalid Card Number” message. If it is a valid combination of digits, it will tell you the type of the card and will color the black-and-white logo on the program’s interface.

This tool has been designed to help you check for typing errors, transpositions, missed keystrokes, etc., that may happen when writing down a credit card number, but it won’t tell you where the mistake is or which the invalid digits are. It will just flag that number as not valid, which is enough in most cases to avoid charging a different card by mistake or validating a transaction that most probably won’t be covered by the credit card issuer.

Easy Credit Card Checker supports all major international credit cards (Visa, MasterCard, Diners Club, and American Express (AMEX)), some regional and specialty cards (Discover and JCB), and some defunct cards, such as Carte Blanche or EnRoute.
