What does it do?

It's actually more about what it prevents. When shopping Stockers Starters, this 3-4 digit security code helps us ensure that the card is in the right hands (it may also be referred to as a CVV2, CVC2 or CCID code). Though it is not required, we ask for this number so we can better protect you from fraud.

Where can I find it?

Visa, Master Card, Discover
The 3-digit code is located on the back of your card, inside the signature area. Typically the signature panel will have a series of numbers, but only the last three digits make up the security code.

American Express
The 4-digit code is located on the front of the card directly above the credit card number on the right.
