Pet Simulator 99!
codes & rewards

New Pet Simulator 99! codes are added to this page as soon as our team confirms them. Bookmark the page and check back regularly, or join the Vaulted Values X Discord to get a heads up when fresh codes drop.

Codes for Pet Simulator 99! are case-sensitive — check capitals and underscores, and avoid trailing spaces if you copy-paste. If the code is correct, it may have already expired, or the game server might need a moment to register a new drop. Try again after a quick rejoin.

It depends on the developer. Most Roblox games release codes around events, milestones (visits/likes), weekend updates, and seasonal launches. There's no fixed cadence — that's why we keep this list current rather than guessing.

Rewards vary per code: in-game currency, exclusive items, boosts, cosmetics, and sometimes pets or units. The specifics for each Pet Simulator 99! code are shown below each code.

Usually no — once a Roblox code expires it stays expired. The exception is anniversaries or themed events, where developers occasionally re-issue an older code for nostalgia. Treat expired codes as a record, not an active option.
