A credit card number typically consists of 16 digits, although it can range from 13 to 19 digits depending on the card issuer. The number is usually grouped into four sets of four digits, separated by spaces or dashes. The first digit indicates the card network (e.g., Visa starts with 4, MasterCard with 5), and the last digit is a check digit used for validation. The card number is embossed or printed on the front of the card, alongside the cardholder's name and expiration date.
