Where Is the Security Code on a Prepaid or Gift Card?

The “security code” is usually the CVV/CVC—a short number printed on the card that helps verify online purchases. On most cards it is on the back, near the signature strip. This page shows where to find it and what to do if you can’t.

Quick safety tip: Never share your full card number, PIN, or security code in chat or email. Only type it into trusted payment forms on secure websites.

Where to find the security code

Most Visa / Mastercard The security code is typically a 3-digit number printed on the back of the card, near the signature area. It may be labeled CVV (Visa) or CVC (Mastercard).
American Express (if your card is AmEx) Many AmEx cards use a 4-digit security code printed on the front of the card (often above the card number). Some prepaid programs may differ.
Not sure which network you have? Look for the network logo on the front (Visa, Mastercard, AmEx). Gift and prepaid cards may also say “Gift” or “Prepaid.”

Common problems (and quick fixes)

1) The security code is scratched off or unreadable

If the digits are damaged, you may not be able to use the card for online purchases. Some issuers can help if the card is registered or if you have proof of purchase. If you can’t read the code, contact the issuer using official details from your card packaging or documentation.

2) The website keeps rejecting the security code

  • Double-check you are entering the correct digits (3-digit vs 4-digit).
  • Try typing the number manually (avoid autofill mistakes).
  • Make sure the card has enough balance for the total, including tax/shipping.
  • Some merchants do not accept certain prepaid/gift cards for online purchases or for subscriptions.
  • If the payment form asks for a billing ZIP/postal code, use the one tied to the card (if your card supports registration).

3) A site asks for a “PIN” instead of a security code

A PIN is different from CVV/CVC. PINs are often used for in-store debit transactions or ATM access (depending on the program). If a site specifically asks for CVV/CVC and you enter a PIN, it will fail.

What not to do

  • Don’t share your security code with anyone who contacted you first.
  • Don’t provide OTP codes to “support” or “verification” messages.
  • Don’t install remote-access apps to “fix” a payment.
  • Don’t post screenshots of the card (even with some digits blurred).
If your card is missing: Go to Lost or Stolen and follow the immediate steps.
