Did you ever wonder how people or computers know what type of credit card you are using without asking?

Credit Card
It’s actually pretty easy. The first digit tells you what type of credit card.
Within the United States:
- VISA cards starts with a 4,
- Mastercards start with 5,
- Discover cards start with 6, and
- American Express start with 3.
This may apply worldwide, but I can’t guarantee it.
Next time a client gives you a credit card number you don’t have to ask, "is that Visa or Mastercard"!
