Hi there! So there is a good chance that the expiration date can be ignored. I can't speak for our EU colleagues, but I know here in NA we have renewed the codes on cards to continue using them despite the listed expiration date.
That being said, I am willing to bet that these codes are likely EU only. As mentioned above, I would try typing in the code to see if it works on NA. If it doesn't, I suggest reaching out to an EU CM via Discord (or the EU Forum if you have an account there) to see if the codes are expired/are only usable on the EU server.
