Will an unused XBL gold card expire?

I was given a Gold subscription card bought at Walmart and I read the back and it doesn't say anything about expiration. I didn't want to use it until my the Gold I have now expires.

So I was wondering will an unused XBL gold card expire?

I dont think it expires.

I'm pretty sure that it doesn't expire, If it's not in the small-print then i really doubt it does.

K thanks. I was googling around before posting this and just wanted to make sure.

It doesn't say anything in the back of the card about expiration and the pin number is not scratched off.

I guess it's still good to go.

Just a note.

I've had a couple of codes (game content/Live) that said they had expired but they still worked anyway.
