What is cvc on card

Last updated: April 1, 2026

Quick Answer: CVC (Card Verification Code) is a three-digit security number on credit and debit cards used to verify the cardholder's identity during online purchases. It provides an extra layer of fraud protection.

Key Facts

What is CVC?

CVC stands for Card Verification Code, a three-digit security code printed on credit and debit cards. This code serves as an additional security measure to verify that the person making an online or telephone purchase actually possesses the physical card.

Where to Find Your CVC

For most credit and debit cards, the CVC is a three-digit number located on the back of the card, usually printed to the right of the signature strip. For American Express cards, it's a four-digit code found on the front of the card. The exact location may vary slightly depending on the card issuer.

CVC vs CVV vs CSC

CVC, CVV (Card Verification Value), and CSC (Card Security Code) are essentially the same thing. Different card issuers use different terminology, but they all refer to the same three or four-digit verification code. Visa and MasterCard use CVV2, while American Express calls it CID (Card Identification Number).

How CVC Protects You

The CVC provides protection against fraud in online shopping. Since the code is only printed on the physical card and not stored in the magnetic stripe or chip, it proves you have the actual card in your possession. This makes it much harder for criminals using stolen card numbers to complete fraudulent purchases.

CVC Security Best Practices

Never share your CVC with anyone except during legitimate, secure online transactions with trusted merchants. Legitimate merchants never ask for your CVC via phone or email. Always verify that you're on a secure website (https://) before entering your CVC. Never write down or save your CVC with your card information.

CVC vs PIN

The CVC should not be confused with your PIN (Personal Identification Number). Your PIN is used at ATMs and point-of-sale terminals for physical transactions, while your CVC is specifically for card-not-present transactions like online shopping or telephone orders.

Related Questions

Is it safe to give your CVC for online shopping?

Yes, it's safe to provide your CVC for legitimate online purchases on secure websites. Always verify the website is genuine and uses encryption (https://). Never share your CVC via email, phone, or text message.

What should I do if someone asks for my CVC over the phone?

Do not provide your CVC over the phone. Legitimate companies never request this information over the phone. This is typically a sign of a scam or fraudulent activity. Contact your bank directly if you have concerns.

Can someone use your card without the CVC?

Having just the card number makes fraud more difficult but not impossible. The CVC adds an extra layer of security for online purchases. Criminals can still attempt to use stolen cards for in-person transactions or phone orders.
