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
