An invite code failing usually means one of four things, and they are worth checking in order: a mistyped code, a code that ran out of uses, an account or window problem, or a dead code. Most failures are the first one. Work through the list below before you discard the code — and know when to stop retrying it and take the next one instead.
Codes are short strings of letters and digits. A single transposed character produces an invalid-code error that looks like a dead code but is not. Copy the code from the wall instead of retyping it, and paste it directly into the redeem field. If you typed it by hand, compare it character by character — especially lookalike characters — and try once more with the pasted version.
Every code has a limited number of uses. On this wall each card shows remaining uses (x/30) with a progress bar: if the bar is at 0, the code is finished and no retry will revive it. Pick a card with uses left instead of re-entering a spent one.
The redeem entry is only available within 48 hours of joining Muse: app → Settings → Redeem token, or web → Settings → General → Usage → Redeem invite code. If that entry is gone, your window has passed and no code will work on that account — the fix is the waitlist path back in, not another code. Separately, if you already redeemed a code on this account, a second code may not apply; that case is unverified for existing accounts, so treat it as a possibility, not a certainty, and check whether the redeem entry is even present before assuming the code is at fault.
Codes on the wall are user-submitted and not guaranteed valid: a code can be used up, revoked, or expired. If the code looks right, has uses shown, and your window is open, yet it still fails, treat it as dead: take the next code, and report the dead one on the wall so it gets hidden after 3 dead reports and the next person does not waste time on it.
| Cause | What to do | Give up on this code when |
|---|---|---|
| Typo | Paste (don't type); compare character by character; retry once | The pasted version fails too |
| Ran out of uses | Pick a card with uses left on the wall | The bar shows 0 |
| Window passed | Redeem entry is gone → waitlist path, not another code | The entry is absent entirely |
| Already redeemed (unverified) | Check whether the redeem entry is present at all | Entry present but a second code still fails — try one more code, then stop |
| Dead / revoked | Take the next code; report this one dead | One pasted retry fails with uses shown and window open |
If your code is dead, go back to the wall and pick by the uses-left bar, not by position: the hero card is random on every visit and is not a quality signal. Copy it, paste it into the redeem field in the same session, and redeem within 48 hours of joining.
