Build a Zoo codes (January 2026) — full working and expired list

Update: We found 3 new Build a Zoo codes on January 24, 2026 and added them to the list.

Build a Zoo on Roblox lets you grow a zoo by hatching animals from eggs and using them to generate cash. Redeemable codes give you shortcuts to rare eggs, Lucky Tickets, gems, fruits, and extra money so you can expand faster without as much grinding.

All current Build a Zoo codes (January 2026)

Use the table below to see every known code, the reward type, and where it currently sits as working or expired. If a code marked “Working” gives an error, it has likely just expired or hit a use limit.

Only a small set of codes is still working in late January 2026, mainly the ones that reward Lucky Tickets and cash. Seasonal and event-themed codes tend to expire quickly, especially those tied to holidays, bug-fix milestones, or limited redemption counts.

How to redeem Build a Zoo codes

Codes are redeemed directly inside the Build a Zoo experience on Roblox. You can use either the Shop menu or the Discord Reward button, depending on which interface the game presents.

Step 1: Start Roblox, then launch Build a Zoo from the game page.

Step 2: Once you load into your zoo, look at the left side of the screen and click the Shop icon to open the Shop menu. In some versions, you can instead click the Discord icon at the top to reach the codes screen.

Step 3: Scroll all the way to the bottom of the Shop or Discord Reward window until you see the Redemption Code or Enter Code text box.

Step 4: Type or paste one code into that box, making sure the characters match exactly. In some interfaces codes are case-sensitive, so copying and pasting is safer than typing from memory.

Step 5: Press Redeem or Check. If the code is valid and still active, a success message appears and the rewards go straight to your account. Repeat the process for each remaining working code.

Each code can only be redeemed once per Roblox account. If you see an error for a code that previously worked, it has most likely expired, reached a global use limit, or been disabled by the developer.

What Build a Zoo codes give you

Build a Zoo codes are designed to accelerate your early and mid-game progress by injecting extra resources and rare items. Rewards broadly fall into a few categories:

• Eggs: Many codes provide special eggs such as Ultra Eggs, Hyper Eggs, Prismatic Eggs, Halloween Egg, Rhino Egg, Rhino Rock Egg, Dark Goaty Egg, Lionfish Egg, Saber Cub Egg, Turkey Eggs, and occasional seasonal eggs like Yeti Egg. These typically hatch into higher–rarity animals than the standard conveyor-belt eggs.
• Lucky Tickets: Lucky Tickets are used for free spins on seasonal or pass-style reward tracks. Codes that stack multiple tickets at once are especially useful when a new season or event begins.
• Cash: Cash rewards, often in the $10,000–$30,000 range, help you buy more eggs from the conveyor, unlock plots, or upgrade systems that influence egg rarity and zoo layout.
• Gems / Diamonds: Gems (sometimes called Diamonds) act as a premium currency. Codes that grant hundreds or thousands of gems let you unlock upgrades, buy special items, or access premium eggs with less grinding.
• Fruits and food items: Fruits such as Banana, Pineapple, Dragon Fruit, and event items like Candy Cane, Cranberry, and Acorn are often used to boost animals or connect to special events. While they are less impactful than a high-tier egg, stacking them from multiple codes is still useful.

Used together, these codes can give a substantial one-time boost: several rare eggs for strong animals, a sizable pile of cash, and enough tickets and gems to engage with events and reward tracks more freely.

Why your Build a Zoo code might not work

A Build a Zoo code that fails to redeem usually falls into one of a few situations.

• The code has expired: Many codes are tied to holidays, seasons, or specific updates. Once that period ends, the code is disabled even if it still appears on older lists.
• The redemption limit has been reached: Some rewards are capped to a specific number of uses, such as the first 40,000 or 80,000 players. After that limit, the code no longer works for new accounts.
• Typing mistakes: Codes are a mix of letters and numbers, and in some menus they are case-sensitive. A single incorrect character will trigger an error. Copying and pasting directly into the text box avoids this.
• Outdated client: When new codes are released, the game may receive an update. If you have stayed in the same session for a long time, rejoining Build a Zoo can help ensure your client recognises fresh codes.

If a code listed as working consistently fails even after rejoining and copying it carefully, treat it as expired and move on to the remaining active codes.

Where new Build a Zoo codes are announced

New Build a Zoo codes are generally tied to events, updates, milestones, or scheduled weekly rewards. The developer uses the game’s community channels and description to roll these out. The most reliable approaches are:

• Checking the game’s description text on the Roblox experience page when you log in.
• Following community channels such as the official Discord, especially any dedicated codes or announcements channels.
• Looking out for update notes or banners inside the game itself, which sometimes highlight new limited-time codes.

Because many event codes do not advertise their exact end date, it is worth redeeming any new ones as soon as you see them rather than waiting.
