You've probably been there. You're staring at the beautiful, slightly terrifying landscape of Nalcott, your Deviant is doing something weird in the corner of your screen, and you realize you're desperately low on Acid or Energy Links. Naturally, you start hunting for once human redemption codes. It’s the classic gamer instinct. We want the freebies. But honestly, the way most sites handle these codes is a mess. They list expired junk from the beta, or they bait you with "active" codes that haven't worked since Starry Studio launched the game globally. It’s frustrating.
Starry Studio, the developers behind Once Human, are actually pretty generous, but they play a specific game with how they distribute these rewards. They aren't just handing out endless loot for nothing. Most of these codes are tied to specific milestones, collaborations, or the ever-shifting seasons of the game. If you're looking for a quick boost to your survival chances, you need to know which ones are real and, more importantly, how to actually get them to trigger in-game because the menu is kind of buried.
The Reality of Active Once Human Redemption Codes Right Now
Let’s get the "live" stuff out of the way. As of early 2026, the pool of codes is constantly rotating. You have the "Evergreen" codes that usually work for new accounts, and then you have the "Seasonal" ones that vanish faster than a Rosetta scout when you pull out a sniper rifle.
Right now, players have had the most luck with codes like OH000001 or ONCEHUMAN. These are the foundational ones. They usually net you some basic starter materials—think Energy Links, maybe some Canned Meat, or a few Sanity Gummies. They aren't going to make you an overnight god, but they help when you're just trying to build your first decent territory.
Then there are the influencer codes. During big updates or the launch of new scenarios like The Way of Winter, Starry Studio partners with streamers. You might see codes like ONCEHUMANLG or codes specific to creators like sacriel or shroud during promotional windows. These are hit or miss. If a code was released six months ago, don't hold your breath. The game's database is surprisingly strict about expiration timestamps.
Wait, why do some people say a code works and it doesn't work for you? Usually, it's a server region thing. Or, more likely, you've already redeemed a "partner" code from the same campaign. You can't just stack ten different creator codes to get infinite rewards. The game recognizes the campaign ID, not just the text string.
How to Redeem Them (Because the UI is Tricky)
Look, Once Human has a lot of menus. A lot. It’s easy to get lost in the blueprints and the memetic trees. To use your once human redemption codes, you don't actually go to the main settings menu.
- Hit Esc to bring up the main hub.
- Click on Shop Events (it's the gift box icon).
- Look at the bottom right of the screen. You'll see a small prompt that says Redeem Code or you might need to press X on your keyboard.
- Type it in. Carefully.
If you get a "Code does not exist" error, it’s expired. If it says "Already redeemed," well, you've been busy. If it says "System busy," just wait ten seconds and try again. The servers sometimes lag when thousands of people are trying to claim the same reward after a patch.

Why Some Codes Give Better Loot Than Others
It's all about the "Event Grade." Most once human redemption codes offer what the community calls "fluff"—stuff you can farm in twenty minutes. But every once in a while, a code drops something significant, like Butterfly's Emblems or specific cosmetic crates. These are usually tied to technical apologies. If the servers go down for an unexpected twelve-hour maintenance, that’s when the "good" codes come out.
Developers use these codes as a form of player retention. In a game that relies so heavily on seasonal resets and "wipes," keeping the player base happy with a steady trickle of premium currency (like Starchrom) is essential. However, Starchrom is rarely given out via text codes. Usually, that’s sent directly to your in-game mailbox. If a website claims a code gives you 5,000 Starchrom, it's almost certainly a scam. Be careful with your account data.
The Problem With "Permanent" Lists
You'll see websites listing 50+ codes. They are lying. There have never been 50 active codes for Once Human at the same time. Ever. Most of those lists include codes from the "Cradle" beta tests or the "Manibus" technical trials. Those databases were wiped. Those codes are dead.
If you want the real deal, you have to follow the official Discord. That’s where the community managers drop the "Flash" codes. These are often limited to the first 10,000 or 50,000 redemptions. If you aren't fast, you miss out. It’s a bit of a "hunger games" vibe, but that's how Starry Studio drives engagement on their social platforms.
Beyond the Codes: Other Ways to Get Free Gear
Honestly, focusing only on once human redemption codes is a bit of a trap. You can get way more stuff by engaging with the Twitch Drops program. Most people forget to link their Level Infinite account to their Twitch account. When a new season starts, watching a streamer for two hours can net you exclusive weapon skins and furniture blueprints that codes will never give you.
Then there’s the "Invite" system. If you use a friend’s invitation code (which is different from a redemption code), you get a shared weapon. This is huge. If your friend has a high-tier legendary SCAR, you can basically "borrow" a version of it for your early leveling. It makes the grind through the early Monoliths significantly easier.
- Check the Mailbox: Seriously, check it every day. Most "compensation" isn't a code; it's a direct delivery.
- The Seasonal Shop: Use your Mitsuko’s Marks. These are earned just by playing, and they buy the cosmetics people think they need codes for.
- Survey Rewards: Occasionally, a pop-up asks for your opinion on the latest patch. Do it. They usually slap 200-300 Energy Links or some premium consumables onto your character for five minutes of clicking.
Navigating the Scams and Fakes
The search for once human redemption codes is filled with bad actors. If a site asks you to "verify" your account by logging in with your Steam or Epic credentials on a non-official page, close the tab. You'll lose your character, your base, and your items.
The only place you should ever enter a code is inside the actual Once Human game client or the official Level Infinite website. There is no "external generator" for these codes. The game's economy is server-side; you can't "hack" a code into existence. If it sounds too good to be true—like a code for a free motorcycle skin—it probably is.
The Role of Community Spreadsheets
If you really want to stay on top of this, look for the community-run Google Sheets. Players on Reddit and Discord maintain live trackers. They’ll mark a code as "Expired" within minutes of it going dead. It’s way more reliable than any SEO-optimized blog post you’ll find in a Google search. These players are the real MVPs, testing codes across different regions (NA, EU, SEA) to see where they actually work.
One thing to keep in mind is that Once Human is a "Seasonal" game. This means that even if you redeem a code for a bunch of materials, those materials might stay in the "Eternaland" bank after a season ends. You have to spend points to bring them into the new season. So, don't hoard your code rewards. Use them when you need them to progress.
What to Do Next
Stop refreshing old lists. If you've tried OH000001 and it didn't work, the "starter" window for your account might have closed, or the code finally hit its global limit. Your best move is to jump into the official Discord and check the "Announcements" or "Events" channel.
Log in during the weekend. Starry Studio loves "Weekend Warrior" type events where they drop a code on a Friday that lasts until Sunday night. These are the most common and usually the most rewarding for the average player.
Lastly, make sure your game is updated. Sometimes the "Redeem" button won't even appear if your client is out of sync with the server's event manifest. Get your client updated, hit the Shop Events tab, and try the latest seasonal strings. Good luck out there in the Stardust—you're gonna need it for those Prime Wars.
Actionable Steps for Players:
- Verify your account link: Ensure your game account is properly tied to your Level Infinite login to receive automated rewards.
- Join the Discord: It is the only 100% reliable source for "Flash" codes.
- Check Twitch Drops: Link your account before the next major patch to grab skins that codes won't provide.
- Use Invite Codes: If you're under level 10, find a high-level player's invite code to get a head start with a powerful weapon.
- Clear your Mailbox: Don't let rewards expire in your inbox; some have a 30-day claim limit.
