To your second point, AMEX uses 4 digit CVV's[1]. However, it's easy to tell the difference between an AMEX and a VISA/MC from the card number alone. 1. https

- Terretta 10y agoFor AMEX, there's still a 3 digit CSC code on the back which you will need from time to time. The 4 digit code on the front is their CID, asked for by most merchants.
- jpatokal 10y agoCitation needed. I have an AMEX in my wallet and it does not have any codes on the back, nor have I ever been asked for one.
- BillinghamJ 10y agoIt does - there is a 3 digit number on the back in the signature strip. The Amex website will ask you for it if you attempt to change your phone number, amongst other similar high-risk transactions.
- baseh 10y agoI have been asked the 3 digit code when booking an airline ticket on a non-US site. During payment it passed through a amex safekey site which I think is kind of like 3d secure http://security.stackexchange.com/a/136296 http://security.stackexchange.com/a/136296

- jpatokal 10y agoNot on mine there isn't. This may be a US-only thing? Some discussion, which doesn't shed a whole lot of light though: https://insideflyer.com/forums/threads/what-is-the-3-digit-code-on-the-back-of-an-amex-used-for.62078/ https://insideflyer.com/forums/threads/what-is-the-3-digit-c...
- BillinghamJ 10y agoAll of my UK Amex cards have it.
- newlog 10y agoAt least most Spanish credit cards use the 3-digits code on the back of the credit card. And it's almost always asked for (but not in amazon iirc).

- saurik 10y agoThe Apple Store (as in, the actual brick and mortar establishment) started using the 3-digit code on the back of my American Express card at some point instead of the 4-digit one at the front (but they are so far the only company I have personally run into which does that).
- hehheh 10y agoOld comment, sorry, but I think AMEX codes are on the front of the card.
- jlgaddis 10y agoI just checked. I have three AMEX cards (Platinum, Blue Cash Preferred, Green) in my wallet. All three have both four-digit numbers on the front as well as three-digit numbers on the back. I don't recall ever being asked for the three-digit code on the back (like I am with most VISA/MasterCard credit cards). It's always the four-digit one on the front.
