What do the numbers on my credit/debit card mean?
That's interesting. Is there anything else I should know about the numbers on my card?
Well, some cards may also have a CVV or CVC code, which are three- or four-digit codes located on the back of the card. These codes help verify that the person using the card has physical access to it, since they are not typically printed on receipts or statements.
