Where is the “Card ID” located?
Visa / MasterCard / Discover For Visa/Electron (CVV2), MasterCard/Eurocard/Maestro/Solo (CVC2), and Discover (CID), the “Card ID” is a 3-digit, non-embossed (raised), reverse italics number printed on the signature panel on the back of the card immediately following the 16-digit credit card number. Sometimes, only the last 4-digits of the credit number are listed before the “Card ID”. American Express For American Express (CID), the “Card ID” is a 4-digit, non-embossed (flat) number printed on the front of every American Express Card on either the left or right side. The “Card ID” is always located above the embossed (raised) credit card number on the face of the card. In some instances, the “Card ID” is located on the left side of the credit card, but is always above the account number. Some cards have a four-digit number embossed below the account number, but this is not the CID number.
