Pet Simulator 99 is one of the most popular pet-collecting experiences on Roblox, developed by BIG Games. You start with no pets and work your way up — hatching eggs, farming coins, and unlocking new zones as your collection grows. Codes work differently here than in most Roblox titles. Rather than frequent promotional drops, functional codes are almost exclusively tied to physical merchandise, though any codes that do surface can unlock exclusive pets and in-game rewards.
Working Pet Simulator 99 Codes
There are no confirmed active codes for Pet Simulator 99 at this time. BIG Games has not issued any free promotional codes, and the codes that have spread through YouTube videos and community posts have been tested and confirmed not to work. The only functional codes are those included with physical merchandise purchases. We check regularly and will update this list the moment new codes go live.
How to Redeem Codes in Pet Simulator 99
Codes are redeemed through the in-game shop, not a standalone code field. Since Update 4, this feature is only available on desktop devices — mobile and console players cannot redeem codes.
Merchandise Codes
Official Pet Simulator 99 merchandise sold through the BIG Games store — such as plush toys and collectible figures — includes a unique code printed under a scratch-off label. Scratching the tag and entering the code in-game unlocks a pet that typically matches the toy it came with, making these among the rarest collectibles in the game.
A few things to keep in mind: each code is single-use and cannot be shared once redeemed. If you buy merchandise from a third-party seller, verify the scratch-off tag is untouched before purchasing. Codes from older Pet Simulator X merchandise are not transferable and cannot be redeemed in Pet Simulator 99.
Preston’s Secret Shop
Once you unlock Area 35, head to the tunnel on the left side of the zone. Inside, a hole in the wall leads to Preston’s Shop. Interacting with Preston brings up a prompt asking you to enter a Super Secret Code. Despite extensive searching by the community, no working code for this location has been publicly confirmed. There are many claims circulating online, but none have proven valid. If the code ever becomes known, this page will be updated right away.
