Build a Zoo Codes (April 2026) — All Active & Expired Codes
Looking for working Build a Zoo codes? You've come to the right place. Below you'll find every active code for Build a Zoo on Roblox, plus a full list of expired codes and a step-by-step redemption guide. We test codes in-game and update this list as soon as Century Farmers drops new rewards.
Table of Contents
Build a Zoo is a tycoon and simulator experience on Roblox developed by Century Farmers. You start with a small, empty plot of land and gradually turn it into a thriving zoo packed with exotic animals, custom enclosures, and happy visitors. The core loop is straightforward: earn Cash from admissions, spend it on new habitats and animals, attract more visitors, and repeat. Gems serve as the premium currency, letting you speed up upgrades and unlock exclusive content faster than Cash alone.
Century Farmers keeps the game fresh with regular updates that introduce new animals, seasonal events, and limited-time cosmetics. Alongside these updates, they release promotional codes that grant free Gems, Cash, pets, hats, and other goodies. Codes are one of the fastest ways to jumpstart your zoo or catch up after a break, and they don't cost a single Robux.
Right now, there are nine active codes you can redeem for 100 Gems, 1,000 Cash, an Easter Pet, a Birthday Cake Hat, a Starter Pack, a Safari Hat, a Paw Print Trail, and a Lion Cub Pet. That's a solid haul for both newcomers and veterans. Grab them before Century Farmers pulls the plug -- older codes have a habit of disappearing without much warning.

How to Redeem Codes in Build a Zoo
Redeeming codes in Build a Zoo takes less than a minute. Follow these steps to claim your free Gems, Cash, pets, and cosmetics:
- Open Roblox and launch Build a Zoo from the game page or search for it using Place ID
105555311806207. - Once you're in the game, look for the Twitter/codes icon on the left side of your screen and click on it.
- A code redemption panel will appear with a text box. Click inside the text box to start typing.
- Type or paste your code into the text box. Make sure it's entered exactly as shown -- codes are case-sensitive.
- Click the Redeem button to submit your code. If the code is valid, your reward will be credited to your account instantly.
If a code doesn't work, double-check the spelling and capitalization. Build a Zoo codes don't contain spaces or special characters, but even a single wrong letter will cause a failure. If the code still fails after verifying the spelling, it's likely been deactivated by Century Farmers. Check back on this page for the latest working codes.
What Do Build a Zoo Code Rewards Do?
Every active code hands out a different type of reward, so it helps to know what each one does and how to get the most value out of it.
Gems
Gems are the premium currency in Build a Zoo. They're harder to earn through regular gameplay compared to Cash, which makes code-based Gems particularly valuable. You can spend Gems on exclusive animals that aren't available for Cash, speed up construction timers, and purchase premium decorations that boost your zoo's visitor appeal. The ROMANCEBLOOMS code gives you 100 Gems for free, which is enough to make a noticeable dent in your first premium purchase.
Cash
Cash is the standard currency you'll use for most of your zoo operations. Building new enclosures, purchasing animals, upgrading habitats, hiring staff, and expanding your zoo's footprint all require Cash. Two active codes -- WEEKENDJOY5 and JUNGLEJIVE -- each give you 500 Cash, totaling 1,000 Cash from codes alone. That's a meaningful boost during the early game when every dollar counts toward unlocking your next exhibit.
Pets
Pets in Build a Zoo follow you around as you manage your zoo. They're purely cosmetic companions, but they're a fun way to personalize your experience. The EASTEREGG2025 code gives you an Easter Pet, and the BIGCATS code rewards you with a Lion Cub Pet. Both are limited-edition companions that you won't find in the regular shop, so they're worth grabbing while they're still available.
Cosmetic Items
Hats and trails let you customize your avatar's appearance inside Build a Zoo. The ZOOBDAY code gives you a Birthday Cake Hat, the SAFARIKING code unlocks a Safari Hat, and the PAWPRINT code adds a Paw Print Trail effect that follows your character. These items don't affect gameplay, but they're a great way to stand out from other players and show off your code-savvy status.
Starter Pack
The WILDSTART code is especially useful for new players. It gives you a Starter Pack that includes a bundle of resources to help you hit the ground running. If you're just starting Build a Zoo for the first time, redeem this code before anything else -- the head start it provides will save you a considerable amount of early-game grinding.
Tips for Growing Your Zoo Faster
Codes give you a strong foundation, but smart decisions will determine how quickly your zoo grows into a top-tier attraction. Here's what experienced Build a Zoo players recommend for efficient progression.
Redeem all codes before you start building. Before placing your first enclosure, claim every active code from the table above. The combined Cash, Gems, and Starter Pack give you enough resources to skip the starter-tier animals and go directly for mid-range exhibits that generate significantly more visitor income per hour.
Invest in high-traffic animals first. Not all animals attract visitors at the same rate. Larger, rarer animals tend to draw more guests to your zoo, which translates to faster Cash generation. Use your code rewards to purchase a few high-traffic animals rather than spreading resources thin across many low-tier exhibits. The income difference compounds over time and pays for itself within a few play sessions.
Position enclosures strategically. Visitor pathing matters in Build a Zoo. Place your most popular exhibits near the entrance so visitors see them early and stay longer. Spread your exhibits across the map to encourage guests to walk through your entire zoo, passing by food stands and gift shops along the way. Ancillary revenue from shops and stands adds up faster than most players expect.
Don't ignore decorations. Decorations aren't just cosmetic -- they boost your zoo's overall appeal rating, which directly affects how many visitors show up. A well-decorated zoo with a few good animals can outperform a bare zoo stuffed with mediocre exhibits. Use some of your Gems on premium decorations that offer the best appeal-per-cost ratio.
Upgrade habitats before expanding. It's tempting to fill your zoo with as many enclosures as possible, but upgraded habitats generate more income per animal than basic ones. Prioritize habitat upgrades for your best-performing exhibits before building new ones. A fully upgraded enclosure with a rare animal can out-earn three basic enclosures combined.
Save your Gems for premium animals. While it's tempting to spend Gems on speed-ups, the best long-term use for them is purchasing premium animals that have high visitor attraction rates. These animals pay for themselves over time through increased admissions revenue, making them a better investment than shaving a few minutes off a construction timer.

Where Do New Build a Zoo Codes Come From?
Century Farmers releases codes through several channels, and knowing where to look means you can grab codes before they expire.
Game updates and patches: Major content updates almost always come with a new code. When Century Farmers adds new animals, habitats, or gameplay features, they typically announce a code alongside the patch notes. Keep an eye on the game's update log for freshly dropped codes after each patch.
Holiday and seasonal events: Codes like EASTEREGG2025 and WINTERWONDER are tied to holiday celebrations. These seasonal codes often carry unique rewards you can't get any other way -- the Easter Pet is a perfect example. They tend to stick around for the duration of the event, but Century Farmers can pull them early if they choose to.
Milestone celebrations: When Build a Zoo reaches visit milestones or concurrent player records, Century Farmers rewards the community with a special code. The GRANDOPEN code was released during the game's official launch, and BETAZOO was available during the early testing phase. Milestone codes sometimes offer larger reward amounts than standard promotional codes.
Social media and community channels: Follow Century Farmers on their social media accounts and join their community Discord. Developers sometimes share exclusive codes through these platforms that aren't announced anywhere else. The Build a Zoo game page on Roblox is another good spot to check for announcements.
Weekend and special promotions: Codes like WEEKENDJOY5 follow a promotional pattern tied to specific occasions. Century Farmers occasionally drops codes to celebrate community events, developer birthdays, or simply to drive weekend engagement. These are harder to predict, but checking this page regularly ensures you won't miss them.
We monitor all of these sources and update this page as soon as new codes go live, so keeping this page bookmarked is the most reliable way to stay current.
