Why codes might not work

  • The code has expired or was time-limited for an event or milestone.
  • Typos or extra spaces — codes are case-sensitive; copy and paste to avoid errors.
  • The code was already redeemed on your Roblox account (each code is one-time use per account).
  • Server or client issues — rejoin the game or restart the Roblox app, then try again.
