CID Example

Visa and MasterCard:
The CID (card identification) number is the three-digit
value printed on the signature panel on the back of Visa & MasterCard
immediately following the credit card account number.
The issuing bank contact number and the CID are normally submitted when
the magnetic strip on your credit card is swiped. Because we do not have
the card present during Internet transactions, banks request that we obtain
the data manually (on each purchase), thus allowing for automated verification
of the credit card. We do not store this number. Since the banking industry’s
introduction of these codes in 2000, this fraud prevention tool is rapidly
being accepted as proof that the card is present during the transaction.
Without these codes, we would need to manually verify addresses with your
bank, which would cause processing delays. Not only does providing your
CID number prevent credit card fraud, it also helps us keep our prices low.
Thank you for your assistance.
