Other four digits on back of card?

[Wordsaremything]

So what are they for??

I've often wondered

The first 4 are the same as the last 4 of your card number. Presume it's to stop fraud in some way (by making sure that the security code 'belongs' to that card?)

Security code and signature strip I mean- so you can't peel off one card and attach to another

A quick check of my cards reveal that two don't have the other four, and on the two that do, it's the last four digits of the card number itself. Not sure what they're for, but as they aren't universal, I assume not a lot!

Are you with lloyds or tsb, as mine has.

Dh is with Santander and he hasn't.

Often wondered as well.

Extra security for remote card use e.g over phone or on internet. If you have stolen a card number it's useless without this code for the banks that use them. It proves you are in physical possession of the card.

I feel sorry for those 4 numbers. No one ever asks for them.

A mystery!

Poor unloved numbers ( :o Thermo)

They are secret numbers. One day you will find them on a hidden box somewhere on a desert island.
Like in Lost.
Hopefully without the Hobbit guy though.

Fluffyears, that's the last three numbers on the security stripy. Op is talking about another set of 4 numbers.

I know my card has some, don't think they are the same as the last 4 digits of my card number because I'd recognise them & I remember wondering too.

Ah right the secret numbers,we need to know!!

my last 3 have rubbed off so my card is very secure!

Only I know them!
