3779 Credit Card Type: IIN/BIN List, Credit Card Numbers + American Express Card Account Numbers

Want to know what credit card starts with 3779? 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.

Major Industry Identifier (MII): What does the first digit ‘3’ in a 3779 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 3779 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 “3779” 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 3779?

A credit or debit card beginning with 3779 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 cards always have a 16-digit number format, never 15.

That’s not the whole story, though! Although every 3779 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 3779 cards in the next section.

What do the rest of the American Express credit card numbers mean?

Now that we know that a 3779 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 “779” 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 six financial institutions issue 100 different American Express 3779 credit cards. We also know that all 100 of the 3779 credit card types are issued in thirteen countries.

What do the rest of the 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 3779 credit card, the 7th to the 14th digits represent the card account number, which is called a Primary Account Number (PAN).

These eight PAN digits are unique to an account holder and link credit card transactions to the customer’s account number. The last digit, called a check digit, is used with an expiration date and CVV for merchant verification and security purposes.

When typing in American Express numbers, it’s always possible to mistype a digit or two. That’s why the check digit, which is the 15th digit of the card number, exists. Check digits are used for the detection of typos and to prevent fraud. The credit card network uses the check digit with the rest of the card numbers to instantly verify that the card number is valid using a mathematical formula called the Luhn Algorithm.

How long are American Express cards valid for?

Most American Express cards are valid for five years from the date of issuance. However, some cards may have a shorter or longer validity period, depending on the card type and the issuer. Cardholders will receive new Amex cards from their credit card company before the expiration date listed on the card.

Where is the CVV on an American Express card?

The CVV on an American Express card is a four-digit number printed on the front of the card, just above the last digits of the card number. CVV (Card Verification Value) numbers are also called CSC (Card Security Code).

What is AmEx account number?

An AmEx account number is a seven-digit number you can only find on physical AmEx cards. The seven-digit number begins with the 5th digit and ends with the 11th digit of the card number.

Can you move credit card debt to another credit card?

You can move credit card debt to another credit card with a balance transfer. When you do a balance transfer, you take out a new loan to pay off your old debt. Balance transfers are an excellent way to save money on interest, as long as you find a card with a lower interest rate than your current card. There are even balance transfer cards with 0% APR for a promotional period. Be sure to carefully read the terms and conditions of any balance transfer before you sign up, as there may be fees involved.

How to change a debit card PIN

You must contact your bank or credit card issuer to change your debit card PIN. They will be able to provide you with a new PIN. Depending on your card issuer, you may also be able to change your PIN online or over the phone.
