Definition:
  1. noun. A verification number, also known as a verification code or CVV (Card Verification Value), is a security feature used to confirm the authenticity of a credit or debit card during certain transactions. It is typically a three or four-digit number located on the back or front of the card and is separate from the card's magnetic strip or account number. The verification number adds an additional layer of security to prevent unauthorized use of the card, particularly in online or over-the-phone transactions where the physical card is not present.
