You know that little three-digit number on the back of your credit card? That’s your credit card signature code, also known as CVV (Card Verification Value) or CVC (Card Verification Code).

It’s like the secret handshake your card uses to verify it’s really you making a purchase.

What is a Credit Card Signature Code?

Why Does It Exist?

Imagine you’re shopping online or over the phone. You can’t hand over your card for the cashier to swipe, right?

So, to prove you’re the rightful cardholder, websites and merchants ask for this code. It adds an extra layer of security, helping prevent fraud and keeping your money safe.

Where Can You Find It?

Flip your card over. See that strip where your signature usually goes? Right there, near the end, you’ll find those magic three or four digits (depending on your card issuer). They’re not embossed like the card number, which means they’re not raised, just printed flat.

What’s with the Different Names?

CVV, CVC, CSC—why so many acronyms? Well, different card companies have their own terms for it, but they all serve the same purpose: security. It’s a bit like how some people call soda “pop” and others call it “soda.” Same drink, different names.

Is It Safe to Share?

Like your PIN, treat your signature code with care. Don’t go plastering it on social media or sharing it with random websites. It’s meant to be a secret between you and your card issuer, helping keep your financial info under lock and key.

Fun Fact:

Ever wonder why it’s on the back of the card? It’s a design choice to make it harder for bad guys to copy. If it were on the front, anyone who sees your card could grab it. Sneaky, right?
