Pet Simulator 99 is one of Roblox’s most-visited experiences, built around hatching, collecting, and upgrading pets across increasingly powerful worlds. Unlike most Roblox games where promo codes hand out free gems or boosts, the code system in Pet Simulator 99 works differently — codes are bundled exclusively with official physical merchandise, and each one is valid for a single use only.
Pet Simulator 99 working codes
There are no active Pet Simulator 99 codes available to redeem right now. Every code that has circulated publicly — through YouTube videos, community posts, or third-party lists — is expired or was never valid. Because merchandise codes are designed for one-time use and are tied to the buyer’s account, they cannot be shared or reused once claimed.
The developers may release new codes alongside future updates or special promotions. When confirmed working codes appear, they will be added to this list immediately.
How to redeem Pet Simulator 99 codes
Note: As of Update 4, code redemption is only supported on desktop devices — the option is not available on mobile.
Preston’s Shop Super Secret Code
Once players unlock Area 35, Preston’s Shop can be found in a tunnel to the left of the main zone, accessed through a hole in the wall. Interacting with Preston pulls up a prompt asking for a Super Secret Code. Despite extensive searching by the community, no confirmed working code for this prompt has ever been made public. If the developers officially reveal it, this page will be updated with that information.

Where to get Pet Simulator 99 codes
Purchasing physical merchandise from the BuildIntoGames store is the only confirmed way to obtain a working code. Eligible products come with a unique single-use code included with the item. Note that physical merch can sell out quickly, so availability varies.
For early notice of any future code releases, the official BIG Games Discord server and the BuildIntoGames account on X (formerly Twitter) are the most direct channels. New codes, if and when the developers release them, will typically be announced there first — and will appear on this page as soon as they’re confirmed.
