Report Abuse. The major Credit cards (Visa Mastercard) almost always have 16 digits. The number will be less than 16 if the card is from a department store or gas station. CupCake Â· 8 years ago.
VisaÂ®, MastercardÂ®, and DiscoverÂ® cardholders: Turn your card over and look at the signature box. You should see either the entire 16-digit credit card number or. just the last four digits followed by a special 3-digit code. This 3-digit code is your CVV number / Card Security Code. American ExpressÂ® cardholders: Look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number. This 4-digit code is your Card Identification Number (CID). The CID is the four-digit code printed just above the Account Number.
