Card Security Code
The card security code is a unique three or four-digit number printed on your credit card. This number is not embossed on the card and hence not printed on receipts making it difficult for anyone other than the genuine cardholder to know it. Credit card issuers refer to this number as the 'Card Security Code', 'Personal Security Code' or 'Card Verification Value'.

	Some cards, have the three-digit card security code number printed at the top of the signature strip on the reverse of the card.
	Others, American Express cards for example, have a four-digit card security code number printed on the front of the card, above the account number.
