Steam leaves region limits to each game's publisher. If a key won't activate, the shop you bought it from handles it: Steam doesn't refund keys bought elsewhere.
From Steam's help pages, read 23 October 2026:
Regions, in the shops' words
- Region not stated
- The listing names no region. At ShopTo, CJS CD Keys and Kinguin, the shop's own terms or every page I checked say these work on UK accounts; at Keycense they vary, so theirs never set a price here.
No platform defines these words: each is the shop's, so check the region on its page before you buy.
