Worked for me. Cheers.

Bro I'm having same issue.. that ones not working neither is VALENTINES23 

Also how new of a player do you have to be for the new player codes to work. I've only been playing. For two weeks and only a few codes have worked for 

new codes are usually ~72 hours, some of them requiring a brand new device for Raid, never having the game on there before etc.

STVALENTINE23 is indeed an older, working code for accounts of all ages. 

edit: to clarify, just tested this on a level 50 alt of mine

Ok thanks I'm gonna try it again... I was thinking the game of the had something to do with it this morning. I'm going to try it again now because I tried so many codes before that it locked me out for an hour LOL

You probably used it already, it was available 2 weeks ago

@trips that's what I thought but usually it has a message when you put in the same code that you've already used. It usually says something like this code is invalid you already used it. Or this code is only for new players.
