Pet Simulator 99 Codes (December 2025)

Pet Simulator 99 uses one-time merchandise DLC codes rather than public gift codes, so most “free” codes you see online will not work.

Updated: December 07, 2025

NO ACTVE CODES

How to redeem codes

Step 1: Launch Pet Simulator 99 from its Roblox page and load into a server on a desktop device (PC or laptop).

Step 2: Click the Shop or shopping cart icon on the left side or bottom of the screen to open the in-game store.

Step 3: Scroll all the way to the bottom of the store window until you see the big green Redeem button.

Step 4: Press Redeem to open the code entry box, then carefully type or paste your official merch DLC code into the field marked Empty.

Step 5: Click the green Redeem! button to submit the code; if it is valid and unused, your exclusive pet or item will be added to your inventory automatically.

Public tests of these codes in Pet Simulator 99 show that they either return “already redeemed” errors or do nothing, so they should be treated as unavailable or expired. Any codes printed inside official toys or plushies are one-time use for the original buyer and cannot be reused once claimed.

Why codes might not work

The code is expired or has been disabled; many widely shared PS99 codes were tied to past promotions or one-time DLC cards.
The code was typed incorrectly; Pet Simulator 99 codes are case-sensitive and must match every letter, number, and dash exactly.
The code has already been redeemed on your Roblox account or on a different account; official merch codes only work once.
You are trying to enter the code on mobile or console when redemption is restricted; recent updates require using a desktop client.
The game session is out of date or desynced; closing Roblox, reopening it, and rejoining Pet Simulator 99 can clear temporary issues.

Where to find more codes

New Pet Simulator 99 codes, when they exist, are usually tied to official merchandise and events rather than regular public giveaways. Fresh DLC codes come printed inside products sold through the BIG Games merch store and selected retail boxes.

For any future public code drops, the main places to check are:

The BIG Games Discord server, especially announcement and update channels: discord.com/invite/biggames
The BIG Games / BuildIntoGames X (Twitter) account for event and update posts: x.com/BuildIntoGames
Official posts from Preston, the lead developer, on X: x.com/prest4n

Bookmark this page — the code list is checked and refreshed regularly, and any confirmed new public codes will be added here.

Pet Simulator 99 codes are time-limited, case-sensitive, and often locked to a single account through official merch DLC. Always redeem codes only inside the in-game Redeem menu, and avoid any third-party “code generator” sites or tools that ask for your Roblox password or personal information.
