How to Redeem Once Human Codes
Redeeming a code only takes a few steps. First, complete the opening tutorial if you're new to the game. Then follow the instructions for your platform.
Redeem Codes on PC
- Launch Once Human and enter the game.
- Press F3 to open the Shop Events menu. You can also access it through the main menu.
- Find the Redeem Code option in the bottom-right corner.
- Enter one of the codes from the table above.
- Confirm the code and check the message on your screen.
- Repeat the process for the other codes.
If the code is accepted, you should receive a confirmation message. Follow any instructions shown in-game to collect your rewards.
Redeem Codes on Mobile
Playing Once Human on your phone? Follow these steps:
- Open Once Human and enter the game.
- Tap the three-dot menu in the top-right corner.
- Open Settings.
- Find Redeem Code near the bottom of the menu.
- Enter your code and tap Confirm.
Enter each code separately. If one doesn't work, move on to the next rather than repeatedly submitting the same code.
Why Codes of Once Human Works?
Sometimes a code gets rejected even when it appears on a working-code list. Here are a few things you can check before giving up.
1. Check the Code Carefully
Once Human codes can contain a mix of letters and numbers. A small typing mistake can make the entire code invalid. Copy and paste it whenever possible, and remove any extra spaces.
2. The Code May Have Expired
Some codes are available only for a limited period. Creator promotions, seasonal events, and special campaigns may have their own deadlines. If a code no longer works, it may have expired since the list was updated.
3. You May Have Already Claimed the Reward
Many redeem codes can only be used once per account. If you've already claimed a reward using a particular code, entering it again won't give you another set of items.
4. Check Your Account or Server
Certain promotions may have restrictions based on the platform, server, region, or account eligibility. Read the error message carefully to see whether the problem is related to your account.
5. Check Your Rewards Again
If the game accepts a code but you can't find the items, wait a little and check your in-game mail or the relevant reward menu. If the rewards still don't appear, try restarting the game.
What Rewards Can You Get From Once Human Codes?
The rewards depend on the promotion attached to each code. Here are some of the items you may receive.
- Starchrom: An important resource used to obtain equipment through the Wish Machine.
- Stardust Secret Crates: Reward crates that can contain useful items.
- Healing Syringes: Consumables that can help you recover during your adventures.
- Mitsuko's Mark: An in-game reward included with certain promotions.
- Event items and gift boxes: Special rewards that may be tied to anniversaries, creator campaigns, or other events.
Not every code provides the same items, so check the reward details before redeeming it.
How to Find More Once Human Codes
New codes can appear during game updates, community events, livestreams, and special promotions. If you don't want to miss the next batch, keep an eye on the game's official channels.
You can check the official Once Human website, join the official Discord community, and follow the game's social media accounts.
It's also worth checking back here when new codes are released. The list can be updated as codes become available or expire.
What should I do if a code doesn't work?
Check the spelling, remove extra spaces, confirm that you haven't already claimed the reward, and try another code. If it still fails, the code may have expired or may not be available for your account.
Once Human redeem codes are worth checking before you head out to explore, fight enemies, or collect resources. They can provide extra items and other rewards without requiring you to spend your in-game currency.
Try the available codes above, starting with those that have a known expiration date. Remember that codes can stop working at any time, so claim your rewards early whenever possible.
