First and foremost, there are many different types of credit cards numbers, such as American Express, Visa, Mastercard, and Discover. With such a variety, each credit card number has some basic similar points. This includes a Major Industry Identifier, typically at the beginning of the credit card number. For instance, American Express credit card numbers have a MII of 34/37, Visa has 4, Mastercard has a range from 2221-2720 and Discover has from 637-641.

To conclude, credit card numbers have very specific components, making them secure and hard to replicate.
