How to Redeem Undertale World Codes
To redeem codes in Roblox Undertale World, you will need to follow these steps:
- Press the Settings Cog/Gear button to the right of your level in the top left corner of the screen.
- Enter a working code in the text box and hit Redeem.
- You’ll get your free code rewards instantly if the code is still active.
- If not, let us know in the comments!
Be sure to use codes from our Undertale World list quickly, as they may expire soon.

Should a newly released code fail to work, consider exiting and then re-entering the game. This action transfers you to a different server, potentially with an updated version of the game where the code functions correctly.

Why Are Undertale World Codes Not Working?
Having trouble with an Undertale World code? Here’s some reasons why it may not be working:
- Check for Typos: Make sure you’ve typed or pasted the code correctly. Even a tiny mistake can invalidate it. Use this guide or the game’s official channels as your source for accurate codes.
- Expiration Date: Codes don’t last forever! Developers might announce when a code expires, but sometimes they disappear without warning. So, grab those goodies quickly!
- Capital Letters Matter: Some codes are picky about capital and lowercase letters. Make sure you match the code exactly.
- Server Hiccups: It’s rare, but sometimes a new code might not work right away on every server. Try logging out and back in, or hopping to a different server.
If you’ve done all this and the code still doesn’t work, it might be gone for good. But hey, leave a comment below if you find an expired code, and I’ll make sure the list is up-to-date.
When Are New Undertale World Codes Released?
Although Cold Dev Studios hasn’t officially stated when new codes drop, I’ve picked up on some trends based on past releases and what’s happening in the community:
- Major game updates usually mean new codes: Developers often toss in a few codes as a little extra something for players after big changes to the game.
- Holidays and special events: Keep an eye on the game’s social media or Discord – they might surprise you with codes during holidays, and big milestones.
- Community milestones: Sometimes, developers give out codes as a reward when the game hits certain goals, like a certain number of likes or players.
- Server hiccups or bugs: If the game has any downtime or annoying glitches, you might get lucky and see some codes pop up as an apology or compensation.
