Want to know what type of credit card starts with 3717? We were curious too! Keep reading and we’ll tell you what we found.

Every credit card has either 15 or 16 total digits. Why not one or the other? It turns out that the total number of digits depends on what card network the card uses. Visa, Mastercard, and Discover use 16 digits while American Express uses 15 digits. Interestingly, every one of those 15 or 16 digits has a hidden meaning. Besides being unique to you, they can tell us what type of card it is, the bank that issued the card, and what account is associated with the card. There’s even a digit at the end that’s used to make sure you entered all the other numbers correctly.

What Does The ‘3’ in Your 3717 Credit Card Mean?

Knowing the card’s first digit helps us discover the credit card network the card belongs to. The best-known credit card networks are Visa, Mastercard, and American Express. Although they’re the biggest card networks, they’re not the only ones! Besides the big three, there’s also Discover, Diner’s Club, Carte Blanche, JCB, and a few smaller ones.

The first digit of the credit card is called a “Major Industry Identifier”. Why? It’s because the first number tells us what credit card network the card belongs to. For “3717” the first digit is a “3”. It turns out that if the first digit is a “3” it’s always an American Express, Diner’s Club, Carte Blanche, or JCB credit card.

This means our card can’t be a Visa, Mastercard, or Discover credit card. Although we haven’t narrowed it down to one car network yet, we do know that a “3717” credit card must be an American Express, Diner’s Club, Carte Blanche, or a JCB card.

How about other credit card prefixes? A card that begins with a “4” is always a Visa card. A “2” or a “5” would be a Mastercard credit card, and a “6” would be a Discover card. It used to be that Mastercard only used a “5” but they also started using a “2” a few years back.

Is a 3717 Credit Card a Visa, Mastercard, or American Express?

A 3717 credit or debit card is always American Express! How do we know that? It’s because every card starting with 34 or 37 is an American Express card! Another clue is that only American Express has 15-digit card numbers. Visa and Mastercard credit and debit cards are always 16 digits, never 15.

That’s not the whole story, though! Although every 3717 card will be an Amex, there are many different types of Amex credit cards. Not all American Express cards are equal! We detail all the different types of 3717 cards in the next section.

What Do The Rest of The American Express Credit Card Numbers Mean?

Now that we know that a 3717 prefix credit card is an American Express card, we’re already part way to solving the secret behind the numbers. To solve the rest of the mystery, we’ll need to decipher the remaining “717” bit.

It turns out that the 2nd through 6th digits of a credit card tell us who the card issuer is and the exact kind of credit card. In credit card industry-speak, these numbers are called the “Bank Identification Number”. Okay, but we only have 3 of the Bank Identification Numbers, not 6. Is that a problem? Nope! We can still solve the mystery behind the numbers by using the 3 remaining numbers that we do have.

What Do The Final Card Digits Mean? (Primary Account Number and Check Digit)

Since you’ve read this far, you might be interested in understanding what the rest of the numbers on your card mean. On your 3717 credit card, the 7th to the 14th digits represent the account holder’s account number, which is called a Primary Account Number (PAN).

These eight PAN digits are unique to an account holder and are the most important part of the credit card number. The last digit, called a check digit, is used for verification purposes to avoid charging purchases to the wrong card number.

When typing in your American Express card number, it’s always possible to mistype a digit or two. That’s why the check number, which is the 15th digit, exists. Check digits are used for the detection of typos. The credit card network instantly verifies that everything was entered correctly by running the check digit plus the rest of the preceding portions of the account number through a mathematical formula called the ‘Luhn Algorithm’.
