How many digits does a MasterCard have? A: A MasterCard has a total of 16 digits. MasterCard, as well as most major credit card systems, use the ANSI Standard X4.13-1983 system, in which each digit identifies a particular attribute of the card.
These are the three-digit numbers on the back of MasterCard, Visa and Discover cards, or the four-digit numbers on the front of an American Express card. These codes were introduced in the late 1990s in response to the need to validate the growing number of Internet transactions.
