How to redeem it on Nintendo
- On your Switch, open Nintendo eShop from the HOME Menu and choose your account.
- Select Redeem Code on the left.
- Enter the 16-character code (not the control number) and confirm.
Or in a browser: ec.nintendo.com/redeem (once you've opened eShop on your Switch)
Nintendo says a code works only on an account from the same country or region, and Nintendo UK tells UK players to check a code is meant for Europe.
From Nintendo's help pages, read 23 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.

Can I buy Splatoon 2 Octo Expansion from an official store?
Not now at the official stores I check: only key shops have it in stock, and each row says which region its key is for.
