Game time Card Region lock question

Hi,

My account is registered under NA region and where I'm staying at right now, all they sell is UK game time cards with 2 months game time.

I've never used card transactions online before and I wish to avoid it as much as possible. My question is, will I be able to redeem the UK game time cards on my NA account? or is that region locked as well like the codes we registered on our accounts for the base game copy?

TIA for anyone who would provide input on this matter. I want to know if it would work before I spend any money.

Ah I want to know this too,
