Build A Pet Factory Codes (August 2026) -- All Active & Expired Codes
There are 16 working Build A Pet Factory codes as of August 27, 2026, and the expired archive is still empty — not one independent tracker logs a retired code. Two pay Cash and Gems outright, one pays Lucky Block crates, and the rest give timed Luck/Money/Gem boosts or unlisted bundles. Update 30 shipped on August 22, 2026 without a new code, and Update 31 is already on the calendar for August 29.
Changelog:
· August 27, 2026 — Re-verified all 16 active codes; expired list still empty. Fixed the supernice reward, dropped an unsourced rebirth gate on 40mvisits, corrected the “all lowercase” claim, refreshed live stats and removed testing language we cannot stand behind.
· August 10, 2026 — Title and meta month rolled to August; no code changes.
· July 4, 2026 — Added 11 codes: notacode, wood123, abc1, water, serg, youfoundthis, Mwx4, bnv7, ktr82, pzq19, jxk55.
Build A Pet Factory is a tycoon experience from the verified Roblox group Truly Interactive, run by solo developer DevSergious. You buy spawners that produce pets, chain upgraders onto the line to raise their value, lay conveyors to move them along, and sell them for Cash. It launched on October 5, 2025 and had taken 52.01 million visits, 164,534 likes and 100,105 favourites, with 1,106 players in-game, when we pulled the Roblox API at 02:39 UTC on August 27, 2026.
Every currency the codes pay out is confirmed by the game’s own store: the live game-pass list sells x2 Cash, x2 Gems and x2 Luck permanents. That check matters on a shelf this crowded with near-identical factory tycoons — a reward naming a currency the game does not have is the clearest sign a list was lifted off a clone. Everything below pays Cash, Gems, timed boosts or Lucky Block crates.

All Active Build A Pet Factory Codes (August 2026)
These 16 codes were listed as working on August 27, 2026. Redeem them promptly — the developer can switch a code off without warning.
| Code | Reward | Status |
|---|---|---|
| 40mvisits | 4x 67 Lucky Block crates | Active |
| supernice | 667 Gems + 2,500 Cash | Active |
| starter | Freebies (rebirth 10+ required) | Active |

| serg | ~2 min Luck/Money/Gem boosts (rebirth 10+ required) | Active |
| youfoundthis | Rewards (rebirth 10+ required) | Active |

Two caveats. Roblox Den’s August 26 sweep still lists Mwx4 and water but flags them for re-check rather than confirmed, so try those first. And the rebirth gates are not equally sourced: rebirth 10+ on starter and 20+ on verygood come from both Try Hard Guides and TheGamer, while the rebirth-10 note on the boost and “rewards” codes is TheGamer alone. supernice and release carry no gate anywhere.
All Expired Build A Pet Factory Codes
There are none. Roblox Den (swept August 26, 2026), Try Hard Guides and Game Rant all publish an empty expired list, and no code on this page turns up in an expired table anywhere we checked. That is unusual for a game ten months old and thirty updates in, but we will not invent an archive to fill the space. The first code to retire gets logged here with its date.
| Code | Status |
|---|---|
| No expired codes recorded as of August 27, 2026. | |

Earn Robux instead →How to Redeem Codes in Build A Pet Factory
The code box sits inside the Shop menu rather than behind a standalone button, and there is no Twitter or bird icon in this game. Roblox Den, TheGamer, Try Hard Guides and UrGameTips all describe the same route and the same red shopping-basket icon.
- Open Build A Pet Factory on Roblox (place ID 135729108619936, universe ID 8881105040).
- Finish the opening tutorial if the side buttons are still locked — the Shop icon will not respond until it clears.
- Press the Shop button, the red shopping basket on the left side of the screen.
- Scroll to the bottom of the Shop window and paste one code into the “code here...” text box.
- Press the green Claim button. Do them one at a time — each code is a single redemption per account.
Why a Code Gets Rejected
- Capitalisation. Mwx4 needs its capital M; the other fifteen are entirely lowercase.
- Rebirth gate. starter needs rebirth 10 and verygood needs rebirth 20. Below the threshold the code fails even though it is live.
- Already redeemed. One use per account, and rejoining or hopping servers does not reset it.
- Stale server. A brand-new code can miss an old server; rejoin to get the newest shop menu.

Where New Build A Pet Factory Codes Come From
Truly Interactive publishes its schedule through the Roblox experience events calendar, the earliest public signal available. On August 27, 2026 it listed Update 30 + Admin Abuse, opened 17:00 UTC on August 22, and Update 31 + Admin Abuse, scheduled for 17:00 UTC on August 29. The place record was last republished on August 22 at 19:54 UTC, matching Update 30. Neither listing carried a code, and no tracker added one after August 22.
Milestone codes are the other dependable source, and 40mvisits is the surviving example. The game had cleared 52 million visits by August 27, 2026, yet no 50-million code has been published anywhere we can see. The game description ends with “Join the group & like the game for rewards!”, so joining Truly Interactive before the next milestone is worth the click.

Frequently Asked Questions
Finish the short tutorial if the side buttons are still locked, press the Shop button (red shopping basket, left of the screen), scroll to the bottom of the Shop window, type the code into the "code here..." box and press the green Claim button.
Sixteen, as of August 27, 2026. Roblox Den's August 26 sweep listed all sixteen active, flagging only Mwx4 and water for re-check. UrGameTips, TheGamer, Game Rant and Try Hard Guides carry subsets of the same list; none of them has a code we do not.
Type it exactly as listed: Roblox Den and TheGamer both state these codes are case-sensitive, and Mwx4 is the one with a capital letter. Then check the rebirth gate on "starter" (10+) and "verygood" (20+). Codes are one use per account and can be switched off at any time.
No. Roblox Den, Try Hard Guides and Game Rant all show an empty expired list as of August 27, 2026, and no code on this page appears in an expired table anywhere we checked.
No. Each code is one redemption per Roblox account, and switching servers does not reset it.
Try Hard Guides and TheGamer both state "starter" needs rebirth 10+ and "verygood" needs rebirth 20+. TheGamer alone also reports rebirth 10+ on the boost and unlisted-reward codes. "supernice" and "release" carry no requirement on any list.
How We Verified This Page
Every code above appears on at least two independent trackers. Roblox Den (registered 2020, published by Dantoo Ltd) ran the most recent full sweep, August 26, 2026, listing all sixteen. UrGameTips (registered 2011) last checked August 12 and carries nine. TheGamer and Game Rant are both Valnet titles, so we count them as one source; their May 2026 lists are where the rebirth notes originate. Try Hard Guides (registered 2021) prints an August headline over a page timestamped June 1, 2026. None of these domains is owned by, or was registered near the launch of, Truly Interactive.
The player count, visit and like totals, game-pass list, update calendar and game description all come straight from Roblox’s own APIs, pulled on August 27, 2026. We have no in-game access to this experience, so we do not claim to have redeemed anything ourselves; where a reward rests on one tracker, we say so above. Full method: how we verify codes.
