3791 Credit Card Type (BIN/IIN List of Amex Credit Card Numbers, Account Numbers, and Test Card Numbers)
Table of Contents
Want to know what credit card starts with 3791? So did we! Keep reading and we’ll tell you what we found out!
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 varies depending on what card network the card uses. Visa, Mastercard, and Discover cards contain 16 digits, while American Express cards contain 15 digits. Interestingly, each of the numbers on a credit card has a hidden meaning. Besides the string of numbers being unique to the cardholder, they can tell us what type of card it is, identify 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 first digit ‘3’ in a 3791 American Express 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 a credit card serves as a Major Industry Identifier (MII) and tells us what credit card network the card belongs to. For a 3791 card, the first number is a “3”. It turns out that credit cards that start with a 3 are always an American Express, Diner’s Club, Carte Blanche, or a 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 card network, we know that a “3791” 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. If the first digit is 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.
What credit card starts with 3791?
A credit or debit card beginning with 3791 is always an 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 3791 card will be an Amex, many different types of Amex credit cards exist. Not all American Express cards are equal! We detail all the different types of 3791 cards in the next section.
What do the rest of the American Express credit card numbers mean?
Now that we know that a 3791 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 “791” 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 (BIN), also known as the Issuer Identification Number (IIN). 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 our three remaining numbers.

Examining the results, we know that eleven financial institutions issue 100 different American Express 3791 credit cards. We also know that all 100 of the 3791 credit card types are issued in the United Kingdom, Canada, Qatar, Lebanon, and Malaysia.
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 3791 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 and to prevent fraud. 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’.
