How to find your credit card security code

By Teresa Bitler

Where your security code is located

It doesn't matter what you call them -- a card security code (CSC), card verification value (CVV or CV2), card verification code (CVC) or even a card code verification (CCV) -- those three or four digits provide an additional measure of credit card security when you make purchases online or by mail order. But, finding them can be confusing, especially if you've never made an online purchase with that specific card. (See slide show, "Credit card security codes.")

The card security code "is one in a series of steps that merchants can take to prevent fraud and verify that the order is being placed by the actual cardholder," says Matthew Towson, senior manager of community affairs for Discover Financial Services, adding that in most cases, the only way for a cardholder to provide the security code is to actually be in possession of the card.

Where you find the security code depends on the card. If you have a Visa, MasterCard or Discover, turn the card over. In the signature box or just to the right of it, you will see a series of digits. However long the series, the final three digits are the security code.

American Express cardholders can find their security code on the front of the card, either to the left or right of the embossed 16-digit card number. These four digits are printed in black, not embossed.

If you can't read the security code for any reason, call the issuing financial institution on the customer service number listed on the back of your credit card. Each financial institution will have its own guidelines for how to handle illegible security codes, but it may require reissuing the card.

Since the security code is a safety feature, just like your PIN number, you will want to protect it. Generally, as long as you have a secure connection, you can safely provide it during online transactions. The merchant is prohibited, for security purposes, from storing the code. However, never provide it to anyone, whether you know them or not, in an e-mail (e-mail is unsecured communication). Once someone has your security code, card number and card expiration, it will appear to the online merchant that they are actually in possession of the card.
