Why you have a unique number on your credit card

Many credit cards are issued and if you’ve ever had to manually key a credit card number, you’ve probably wondered why the number is there.

Actually, each digit in a credit card number is important for validation, security and identification during credit card processing. Take a moment to learn what each of these digits means.

Most people own a credit card and carry it with them. The credit cards typically, have sixteen digits on the front. These digits are the unique account number for the card. This is because credit cards have their own unique numbers to uniquely identify them.

This tells you what bank issued the payment card. The payment card type like whether the credit card is a Visa, or Mastercard. To the country of origin of the card issuer as well as the unique account number of that particular cardholder.

There’s also the CVV number which is the 3 or 4 digit code, usually on the back of the card. This is a security code of sorts. Ideally the only party that should know your CVV number besides you is the card issuer (so they can verify that there’s a match).

Of course there’s also the expiration date, which is another set of numbers on the card. Usually it’s in a MM/YY format. So a card expiring in January 2019 would read 01/19. And also with the card number it’s this standardisation that allows consumers to use some credit cards anywhere in the world.
