Credit Card Number Validator is a free Android application that verifies the validity of a credit or debit card number and identifies its type. It supports all the major card brands, such as VISA, MasterCard, American Express, Diner's Club, JCB, and Voyager. Additionally, the app allows you to find public data by using the credit card BIN. By entering the first six digits of the card, you can reveal its country, type, and bank information. The app also features a bank BIN database that enables you to search for the first six or eight digits of a credit BIN number.

The app uses Lehn's algorithm to validate the card number and provides information about the card issuer, country, and type, including debit or credit, MasterCard, Diner's Club, VISA, American Express, and more. However, it is important to note that the app only verifies the card number's validity and not if it is fake. Credit Card Number Validator is not affiliated with any financial institution or bank, and it does not store or transmit any card numbers. It is a useful tool for anyone who needs to verify credit or debit card numbers quickly and easily.
