Once Human has an official redeem-code system, but codes are time-limited and rotate fast — many expire within days. We publish the reliable redemption method rather than stale code lists.
How to redeem
PC: open the Shop by pressing F3, go to the Event tab, and click 'Redeem Code' in the bottom-right. Mobile: open the settings menu (top-right), then select 'Redeem Code' at the bottom. Codes are case-sensitive (copy-paste them exactly), you must have finished the 'Eve of Evolution' tutorial first, and rewards arrive in your in-game Mail rather than directly in your backpack. Official codes are distributed through Once Human's official channels (site, social media, livestreams) and, occasionally, content creators; most expire quickly with no in-game warning.
Where real codes come from
Watch the official channels — in-game mail, the official Discord/social accounts and the official site (www.oncehuman.game). Ignore third-party "active code" lists — they go stale quickly.
