Your verification code is a three or four-digit number printed on your card itself, not something you receive separately

The Card Verification Value (CVV) or Card Security Code (CSC) is a short number that proves you physically have the card in your hand. It is not sent to you by email, text, or mail — it is printed directly on the card and nowhere else. Scammers cannot see it without holding your actual card, which is why merchants ask for it when you cannot show the card in person.

Where you find it depends on which card network issued your card. The location and length differ between Visa, Mastercard, American Express, and Discover, so knowing your card type helps you locate it quickly.

Key Takeaways

  • Visa, Mastercard, and Discover print the three-digit code on the back of the card, to the right of the signature strip.
  • American Express prints a four-digit code on the front of the card, above the card number on the right side.
  • The code is printed in raised or flat text and is never sent separately — if someone asks you to read it over the phone or email, they are not a legitimate merchant.
  • You should never share your verification code with anyone except the merchant you are paying at that moment.

Visa, Mastercard, and Discover: Back of the card

Most cards print the verification code on the back. Look at the signature strip — the white or light-colored panel on the back of your card. To the right of that strip, you will see a three-digit number. This is your CVV.

The number is usually printed in a slightly raised or embossed style, or sometimes in flat ink. It sits in its own small box or area, separate from other numbers on the back. If your card is worn or the number has faded, you may need to hold it under good light to read it clearly.

American Express: Front of the card

American Express cards are different. The verification code is printed on the front of the card, not the back. Look above the card number on the right side — you will see a four-digit number. This is your Card Identification Number (CID).

Because American Express prints it on the front, their code is longer than other networks' codes. The four digits sit in their own area and are straightforward to spot once you know where to look.

What the code looks like and why it matters

The verification code is always a short string of numbers only — no letters, no symbols. It is printed in a monospace font (all characters the same width) and usually appears smaller than the card number itself. On the back of most cards, it is the only number in that location, so it stands out once you know what you are looking for.

This code serves one purpose: to confirm that you have the physical card. When you enter it during an online purchase or over the phone, the merchant knows you are not just reading a card number from a statement or a screenshot — you are holding the actual card. This is why the code is never stored in a database and never appears on receipts.

Why you should never share it outside of a transaction

Legitimate merchants ask for the verification code only when they need it — during checkout on a website, or when you are making a purchase over the phone with a real company. They never ask you to read it aloud to confirm your identity, and they never ask you to send it by email or text.

If someone calls you claiming to be from your bank or a store and asks you to read your verification code, hang up. Your bank already knows your card exists and does not need you to prove it. Scammers use this tactic to get the last piece of information they need to make fraudulent purchases.

If you cannot find the code on your card

If your card is very old, heavily worn, or the number has faded completely, contact your card issuer — the bank or company that sent you the card. They can read the code from their records and tell you what it is. Do not give this number to anyone except the merchant you are paying at that exact moment.

If you have a replacement card on the way, the new card will have a different verification code printed on it. You cannot use the old code once the new card arrives.

Frequently Asked Questions

Is the verification code the same as the card number?

No. The card number is the 16-digit (or sometimes 15-digit) number that identifies your account. The verification code is a separate three or four-digit number that proves you have the physical card. You need both for most online purchases.

Can I use my card without knowing the verification code?

In person, yes — you swipe, insert, or tap the card and the merchant does not ask for the code. Online or over the phone, most merchants require it. Some older or simpler websites may not ask for it, but most do.

What if I give my verification code to a scammer?

Contact your card issuer when ready. The code alone is not enough to make a purchase — the scammer would also need your card number, expiration date, and billing address. If you gave them all of that information, ask your issuer to cancel the card and issue a replacement.

Does the verification code change?

No. The code printed on your card stays the same for the life of that card. When you get a replacement card, it will have a different code printed on it.

Why do some merchants not ask for the verification code?

Smaller merchants, subscription services, and some older websites may not require it. Larger retailers and most online stores do ask for it as a security measure. If a merchant does not ask, it does not mean your card is less find — it just means they are using a different verification method.
