Redemption Guide
5 platformsOnce Human redeems promotional codes inside the game. The exact button location varies by platform and client version, and the Event-screen shortcut was restored after the game also added a Settings-based redemption route.
Settings from the game menu.Account.Redeem Code, enter the code exactly as issued, and confirm it.Events with F3 and use Redeem Code from that screen.Settings.Redeem Code near the bottom of the settings screen.Settings.Redeem Code near the bottom of the settings screen.Settings.Redeem Code.Redeem Code option.Settings.Redeem Code.Redeem Code option.Code Rules & Troubleshooting
Each standard code can normally be claimed once per account, while some creator-code families share a single redemption allowance. Codes are case-sensitive, and expiry or redemption limits vary by campaign.
If a code fails, first check every character and remove accidental spaces. Then confirm that the code belongs to your server scope, that you have not already claimed it or another mutually exclusive creator code, and that the campaign has not expired or reached its redemption limit. Invitation codes and world-chat passcodes use separate systems and should not be entered in the normal Redeem Code field.
New Code Announcements
New Once Human codes have appeared through official X, Facebook, Instagram, TikTok, YouTube, Discord, Reddit, livestreams, creator campaigns, partner giveaways, anniversaries, and platform events. Major updates do not automatically include a code, so campaign and community channels remain important alongside the official news feed.

Once Human Codes FAQ
7 questionsCommon questions about redeeming Once Human codes.
Yes. The current PC, mobile, PlayStation 5, and Xbox Series X/S versions support in-game code redemption. The exact menu position varies by client, but Settings and the in-game Event or Shop screens provide the current redemption routes.
Finish the opening tutorial and early Eve of Evolution progression, then reopen the menu. The Event or Shop shortcut can remain unavailable until the early tutorial steps are complete, while supported clients can also expose Redeem Code through Settings.
No. Some creator-code groups share a one-per-account redemption limit, so claiming one code from that group can prevent another equivalent creator code from paying out on the same account.
Reward delivery can vary by promotion. Check the redemption result first, then check your inventory and in-game mailbox if the items are not immediately visible.
No. Once Human has used chat passcodes that are entered in world chat instead of the Redeem Code interface. A chat passcode should not be treated as a normal promotional Redeem Code.
No. Invitation and Play with Friends codes belong to separate referral systems with their own eligibility rules. They should not be entered or cataloged as normal promotional Redeem Codes.
Yes. Enter each code with the same capitalization shown in the distribution because changing letter case or confusing similar-looking characters can make a valid code fail.
