Credit cards, such as MasterCard, Visa, and Discover, all have unique, identifying numbers as their first digits, with the exception of American Express, Diner’s Club and Carte Blanche, which share the same first digit: the number 3. MasterCard’s unique first digit is 5, while Visa’s is always 4.
What numbers to Visa cards start with?
Visa credit card numbers start with the number 4. Each credit card has a unique string of numbers, but the first one or two digits can help you identify the payment network. A Discover card’s first digit is the number 6, Mastercard’s is 5, and American Express card numbers start with 3.
Is it safe to give last 6 digits of credit?
The first 6 are the BIN number, but each bank has many, so they’re not as easy to guess. On the other hand, the missing 6 digits leave a million of options to brute force. Even if someone does guess your full credit card number – you’ll just cancel it and get a new one.
