Ever wonder why American Express (Amex) insists on that 4-digit code on their cards?

It's more than just a random set of numbers – let's dive into why Amex uses this extra layer of security!

Number 1. Why Does Amex Use A 4 Digit Code?

Alright, let's get to the juicy part first – why does Amex make us remember yet another set of numbers? That 4-digit code you see on the back of your Amex card is called the Card Verification Value (CVV).

Think of it as your card's secret handshake with online vendors and over-the-phone transactions. It's like having a PIN for your card but for those times when you're not swiping it in person.

So why is this necessary? Well, in the vast world of online shopping and virtual payments, fraudsters are always lurking. That CVV acts as an extra layer of defense against unauthorized transactions.

It's data that businesses aren't supposed to keep, making it harder for cyber thieves to get their hands on everything they need to make a fake purchase.

So next time you're entering that code, remember – it's helping keep your hard-earned cash right where it belongs: in your pocket.

Number 2. What is the 4 digit code on a credit card called?

Alright, now that we know why it's there, what exactly is this 4-digit guardian called? It's CVV, which stands for Credit Card Validation Value.

This little code is usually embossed or imprinted on the back of your Amex card, right near your signature. Sometimes it's also called the Card Verification Code (CVC) or Card Security Code (CSC).

But what's its job besides being a tongue-twister? The CVV is like a secret code only you and the legitimate vendors are supposed to know. When you provide this code during an online transaction, it's a way of proving that you physically possess the card.

This is crucial because just entering the card number and expiry date isn't enough to guarantee the person making the purchase is actually you.
