Pet Simulator 99 keeps players hatching, trading, and hunting for rare companions, and codes are one of the few shortcuts to free rewards. Most codes here come from merchandise packaging or limited promotional pushes, so the working list changes without much warning.

How to redeem codes in Pet Simulator 99
A successful redemption triggers a reward popup and adds the item or currency directly to your inventory. If you get an error message instead, double-check the spelling and capitalization before trying again.
Preston’s secret code in Area 35
Separate from merchandise codes, Pet Simulator 99 hides a vendor named Preston inside a tunnel to the left of Area 35, reached through a hole in the wall. Interacting with Preston prompts a text box asking for a “Super Secret Code,” but no one has confirmed a working code for it. No official next reveal date is currently confirmed for this code.

Where new codes come from
Most Pet Simulator 99 codes ship inside physical Pet Simulator merchandise, such as plush toys with a scratch-off tag. Each printed code redeems once, so buying second-hand merch carries the risk that a previous owner already claimed it. Promotional codes tied to milestones or events show up far less often, and when they do, they typically get posted on the official BIG Games Discord server or the studio’s X account first.
Check back regularly, since this list gets updated as soon as new codes are confirmed working.
