Why isn't my Undertale Dungeons code working?
The usual reasons a Undertale Dungeons code fails, in order of likelihood:
- It just expired. Codes can stop working without notice — if a code fails, it may have expired since our last check. Codes the majority of sources report as dead move to the expired list above.
- Typo, casing or spaces. Codes are usually case-sensitive and must match exactly — use the Copy button instead of typing by hand, and watch for trailing spaces.
- Old server. After a game update, some codes only register on fresh servers — leave and rejoin Undertale Dungeons, then try again.
- Limited or one-time codes. Milestone codes (noted in their status details in the table) often die once their milestone passes, and every code can only be redeemed once per account.
