Redemption Guide
4 platformsPick the method for your platform. Enter each code exactly as shown and confirm the correct account and server before submitting.
Code Rules & Troubleshooting
Each standard Once Human redeem code works once per account, and some creator-code groups allow only one code of the same type per account. The Redeem Code option becomes available after you complete the Eve of Evolution tutorial. Expiry varies by campaign, and a code with no published expiry is not guaranteed to stay active.
If a code fails, check the spelling and capitalization first, since Once Human codes are case sensitive. Next, make sure it has not already been claimed on your account, confirm that Eve of Evolution is complete, and check whether the code has expired or carries a creator, server, platform, or account restriction.
New Code Announcements
New Once Human codes appear through the official news page, X, Facebook, Instagram, TikTok, YouTube, Discord, and the official Reddit community, especially around updates, livestreams, anniversaries, and platform events. The official Reddit community was the fastest channel for the August 12 Console Launch AMA codes, while livestream and seasonal codes also appear on X, Facebook, and YouTube as their events go live.

Once Human Codes FAQ
5 questionsCommon questions about redeeming Once Human codes.
No live console redemption route is available as of August 12, 2026. Once Human launches on PlayStation 5 and Xbox Series consoles on August 25, 2026, so use the current Windows or mobile version for eligible codes before then.
No. Some creator-code groups allow only one code of the same type per account, so redeeming one can block the others in that group. Choose the creator reward you want before claiming a code from the same series.
Most standard code rewards are credited to your account after a successful redemption. If the reward is not immediately visible, check your inventory and in-game mail before trying the code again.
No. Once Human has also used anniversary passcodes that must be entered in world chat instead of the Redeem Code interface. A chat passcode should not be expected to work in the normal code box.
No. Redeem codes are promotional strings entered through the Redeem Code interface, while friend and invitation codes belong to separate referral systems. A friend code should not be expected to work in the promotional code field.
