Underground War codes not working? Common fixes

People often search Underground War codes not working after a code fails. Try this checklist:

1. Copy the code exactly — no extra spaces; Roblox codes are usually case-insensitive, but typos break redemption.
2. The code may have expired — compare with the Underground War expired codes list above.
3. Account or level requirements — some codes need a minimum level or progress; the in-game message will say so.
4. Server or update delays — right after an update, redemption can glitch; rejoin Underground War on Roblox and try again.
5. Official sources first — new codes ship via developer social channels; we mirror them here when verified.

If a brand-new code still fails for everyone, it was likely mistyped by the source — check the developer’s Discord or X post and compare spelling.
