Know your Credit Card: 16 Digit Number, CVV, Chip
Credit or debit cards have become part of our daily lives, but have you ever wondered what the numbers on your credit card mean?

What do the numbers on the front of credit card mean?
In addition to the name of the bank and the cardholder, you will also find the number of the credit card, which is made up of 16 digits, grouped 4 by 4 for easy identification.
The first 4 digits refer to the identification number of the entity issuing the card. For example:
- If it starts with a 4, we can tell you that the plastic belongs to Visa.
- If it starts with a 5 is MasterCard
- If it’s a 3, it’s American Express.
- If you have a 6 as the first digit, it could be from some business
From digit 5 onwards, they identify the cardholder and the account to which it is associated.

On the front of your plastic, you will also find the expiration date marked with the month and year. Also, in some of them you can see the year from which you have that card.
Why there is a security chip on your credit card?
Electronic chip is the soul of the card. You may remember that some years ago the cards only had the magnetic stripe, but now, for security reasons, financial institutions embedded electronic chips on the card.
The great goodness of this system is that it avoids identity theft, since it transfers data instead of storing it.
