What is a CVV? The three digits on the back of your card

A CVV, or card verification value, is the short security code printed on a payment card. On most cards it's the three digits on the back; on American Express it's four digits on the front. Card brands call it different names, such as CVC or CID, but it does the same job.

Why it's asked for

When you pay online or by phone, the shop can't see your physical card. Asking for the CVV helps show that the person paying has the card in hand, not just a copied card number.

Why it must never be stored

Card industry rules (PCI DSS) forbid businesses from storing the CVV after a payment is approved, even if encrypted. So if a shop's systems are breached, the codes shouldn't be there to steal.

Keeping it safe

  1. Only enter it on secure checkout pages you trust.
  2. Never share it by email, text or social media.
  3. If you think it's been exposed, ask your card provider for a new card.
