• Launch Subterra on Roblox.
• Head to the Codes NPC area on the right side of your spawn point.
• Enter a working code in the text area.
• Click the Claim Code button to get rewards.

How to Get More Subterra Codes

New Subterra codes are usually shared by the game’s developers through their official social media pages, Discord server, or Roblox group. Keeping an eye on these platforms helps you catch the latest codes before they expire. You can also check fan communities and reliable gaming websites that regularly update Subterra code lists. Refresh the game’s code menu now and then, as new events or updates often come with fresh rewards.

So, if you want to get the codes as soon as they’re released, consider bookmarking this page. Since we update the code list frequently, you don’t need to look for them anywhere else.

You can consider checking the official Subterra Discord server, where you’ll get the list of active codes in the ‘game-announcements‘ channel. Finally, make sure you join the Polyworks Studio community on Roblox to get their latest posts.

Which Subterra codes are still working in September 2025

No Subterra codes from September 2025 are confirmed working as of January 2026, since most have expired with game updates and milestones. Sources from that period listed codes like 8KLIKES, 40KFAVS, and 400KSPELUNKERS, but later checks mark them as invalid.​

Sites published near September 2025 highlighted these as working then, often rewarding Chrono Shards:
