Types of Cards (Basic)

    As you know, there are different type of network integrated to an debit or credit card. The most common one are VISA, MasterCard and American Express.

These brands are known as Card Association.

    So let us get to the point, when you receive your card, you always get different numbers but come cards can come up with the same first digit. That same first digit applies to all cards with the same network; VISA, MasterCard, etc.

    Each card has their own unique numbers to associate it with the card owner. Each card have their own CVV2 (I will discuss about this in another post) to authenticate the originality of the card.

So what are the types of cards and their digits?

1. American Express (Amex) = 3*** **** **** ****
2. VISA = 4*** **** **** ****
3. MasterCard = 5*** **** **** ****
4. Discover = 6*** **** **** ****
