Redeeming codes in Build a Zoo takes less than 30 seconds once you know where to look. I've tested every single code on this list personally, and here's the exact process that works every time:

Since launching in July 2025, it's attracted over 100 million visits from players drawn to its unique conveyor belt egg system and adorable cubic animals.

New codes typically drop every 1-2 weeks, with major updates bringing 3-5 codes at once. Limited codes like CE8CWQDFZSH appear during special milestones and expire quickly, so checking daily ensures you never miss exclusive rewards.
Code failures usually happen due to three reasons: you haven't completed the tutorial yet, the code has expired (especially limited-use ones), or there's a typing error. Always copy-paste codes directly and restart the game if problems persist.
Each code works once per account - you can't redeem the same code twice. However, codes work across all your Roblox accounts, so alternate accounts can claim the same rewards separately.
Hyper eggs and Prismatic eggs from codes U2CA518SC5 and 55PA21N8y2 provide the highest value, offering 30,000+ coins plus premium pets that generate 5x more income than standard animals.
Yes, most codes expire within 2-4 weeks of release. Limited-use codes like CE8CWQDFZSH expire even faster once their redemption cap is reached. We update our expired list immediately when codes stop working.

While Century Farmers hasn't announced Season 2 officially, based on their update pattern, expect new seasonal content in October 2025 with fresh codes and exclusive pets.

Success in Build a Zoo comes down to staying informed and acting quickly on new codes. I personally bookmark this page and check it alongside the official Discord every morning. The difference between casual players and zoo tycoons often comes down to who grabs those limited codes first.
