Once Human Codes: Active and Expired (June 2026)
Last checked June 21, 2026 (UTC)
Once Human codes are the freebies Starry Studio drops around updates and events in this open-world survival shooter, and I keep this list to the ones still redeeming. Most hand over Starchrom and crates. We refresh it whenever new ones land.
Once Human codes are the redemption codes the team posts on the official channels and during update events for free Starchrom (the premium currency), Mitsuko's Marks, energy links, and crate or cosmetic items. Once Human is an open-world survival shooter where you build a base, craft gear, and fight Deviants across a strange post-apocalypse. Starchrom pulls blueprints and cosmetics from the wish machine, Mitsuko's Marks buy gear, and crates hand over resources. The codes mostly speed up unlocking the blueprints and gear that keep you alive and shooting straight.
Quick tip. honestly, spend your Starchrom on weapon and gear blueprints you'll actually run rather than chasing every cosmetic. Power here comes from your blueprint calibration and build, so the gear you fight with improves survival far more than a skin that just changes your look.
Codes turn up around major updates, new scenario launches, and seasonal events, and each one has a window before it expires. You redeem them in game through the settings code option or on the official redemption page, and they're case sensitive.
- Redeem in game through the settings code option or the official page.
- Most Once Human codes give Starchrom, Marks, and crates.
- Codes expire once their event window closes, so redeem early.

Once Human codes FAQ
What do Once Human codes give you?
Mostly Starchrom, Mitsuko's Marks, energy links, and crate or cosmetic items. Starchrom pulls blueprints and cosmetics, Marks buy gear, and crates hand over resources, so the rewards speed up unlocking the blueprints and gear that improve your survival and combat.
How should I spend code Starchrom?
On weapon and gear blueprints you'll actually run. Power comes from your blueprint calibration and build, so the gear you fight with improves survival far more than a skin that only changes your look. Prioritize blueprints.
Why does my code keep failing?
Three usual causes. It expired, you already redeemed it, or you mistyped it. The codes are case sensitive, so paste from the Copy button to keep the exact form.
Where do I redeem the codes?
Two spots. In game through the settings code option, or on the official Once Human redemption page in a browser. Either way the rewards land in your in-game mail, ready to claim.
Do codes carry across PC and mobile?
Once Human shares your account across its supported platforms, so a code redeemed on one applies to the same character. The Starchrom and items show up wherever you log in, as long as you're on the same server and account.
Where do the newest codes show up?
On the official Once Human channels and in-game events. They drop around updates, new scenario launches, and seasonal events, usually alongside the patch notes.
