Microsoft says games got in one country or region might not work in another, and Xbox asks that your Microsoft account's region match where you live. If you bought the wrong code, Microsoft says to contact the shop.

From Microsoft Store's help pages, read 24 October 2026:

Regions, in the shops' words

Europe, EU, EU & UK, EMEA
Sold for Europe, and the shops' pages I checked say these activate on UK accounts. The platforms don't name the UK: Nintendo UK says to use a code meant for Europe, and PlayStation's terms ask for one from your account's country.

No platform defines these words: each is the shop's, so check the region on its page before you buy.

How much is Call of Duty: Modern Warfare III?

On Xbox, from £67.72 at CJS CD Keys (Vault Edition, key, no checkout fees); on PlayStation, from £148.35 with the £10.23 fee its feed gives at Kinguin (key, plus fees at checkout); on Microsoft Store, from £26.09 at CJS CD Keys (key, no checkout fees); on Steam, from £52.11 at CJS CD Keys (key, no checkout fees). Prices checked 14 November 2026.

Can I buy Call of Duty: Modern Warfare III from an official store?

Yes: ShopTo.Net sells it on Xbox, from £76.85.

Will a Call of Duty: Modern Warfare III key work on a UK account?

The prices I lead with are only from offers their shop says work on a UK account. Xbox says a code has to match your Microsoft account's country or region, and that using a VPN to get round it can get a purchase reversed or the account restricted. PlayStation's UK terms say a code works only on an account registered in the country the code is for, and its help pages say an account's region can't be changed. Microsoft says games got in one country or region might not work in another, and Xbox asks that your Microsoft account's region match where you live. If you bought the wrong code, Microsoft says to contact the shop. 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.

How do I redeem Call of Duty: Modern Warfare III?

Xbox codes are redeemed on your console or at xbox.com/redeem, and the game stays on your Microsoft account. PlayStation codes are redeemed on your console or in PlayStation Store online, and only work on an account from the region they were sold for. Microsoft Store codes are redeemed in the Xbox app on Windows or at redeem.microsoft.com, and the game stays on your Microsoft account.
