Prior Extinction Codes [Colossal] (September 2026) – Free Amber & Eggs
· September 11 — re-verified RecodeRelease! and HaveSomeEggs!; flagged four archive codes as Retro-attributed
· September 6 — month-rollover audit; code list unchanged
· August 27 — moved WelcomeBack!, Welcome26 and LunarFixes! to the expired list
Prior Extinction codes pay out Amber, the currency you spend on dinosaurs, plus special eggs that unlock colour morphs. Two codes work as of September 11, 2026, and they are redeemed from the CODES button on the Main Menu — before you pick a dinosaur. Everything below was re-checked today.
Prior Extinction (place ID 6698800091, by the Roblox group Jacys Studios ROBLOX) is a dinosaur survival game where you grow, hunt, nest and fight as a prehistoric animal. Amber buys dinosaurs, fossils discount those purchases, and eggs unlock colour variants such as Melanistic and Leucistic. Read live on the Roblox APIs on September 11, 2026: 111,456,911 visits, 355,818 favourites, a 78.5% like ratio (95,178 likes to 26,050 dislikes), and a median of 2,146 concurrent players across sixteen readings between September 8 and 11, 2026, peaking at 4,091 on September 5. Codes are case-sensitive and work once per account. For the rest, start at the Prior Extinction hub.
All Prior Extinction Codes (September 2026)
Active Prior Extinction Codes
Three independent sources listed both codes as working when we read them on September 11, 2026. Type them exactly, capitals and exclamation mark included. Neither is new: both were live at our August 19, 2026 check, and the September 5 update did not add one.
| Code | Reward | Status |
|---|---|---|
| RecodeRelease! | 5,000 Amber, 1 Melanistic Egg, 1 Leucistic Egg | Active |
| HaveSomeEggs! | 2 Melanistic Eggs, 2 Leucistic Eggs, 2 Garden Eggs, 2 Retro Eggs | Active |
The one disagreement, stated plainly: a single tracker network shows WelcomeBack!, Welcome26 and LunarFixes! as working while calling HaveSomeEggs! expired — an exactly inverted list. Two sites in it publish the same rows in the same order with the same reward wording, so they are one source, not two. Three unconnected sources, read on September 11, 2026, put HaveSomeEggs! in the working column, so that is where it stays.
Expired Prior Extinction Codes
These 32 codes no longer work; the archive tells you at a glance what is not worth typing. The official wiki prices ten of them at 10,000 Amber each, and its trivia note says most Prior Extinction codes were tributes to the game's content creators.
Two caveats. Six are still coloured “Valid” on the official wiki — TunnelDweller, PostTV, HotSmudge, WoofWoof, JurassicUpdate, GemFix — but that table has had no content edit since January 7, 2025, so the green labels are stale. And four sit here on disputed attribution: Return2022, 2yearsBirthday, 11 million and 2021 appear only on an abandoned community wiki, filed under headings reading "Retro2022" and "Retro2021", so they may belong to Prior Extinction – Retro instead. Dead either way.

Earn Robux instead →How to Redeem Codes in Prior Extinction
The redeem box is on the Main Menu, not inside a match. The official wiki gives the Codes location as "In the Main Menu" and lists that screen's buttons in order: Play, Servers & Gamemodes, Tutorial, Skills, Controls, Leaderboards, Mastery, Codes, Credits, Shop, Settings and Achievements.
- Open Prior Extinction (place ID 6698800091) and let it load onto the opening splash screen of rules and latest updates.
- Click through to the Main Menu — the screen with the dinosaur slideshow background and the Play / Tutorial / Mastery button column.
- Press CODES in that column to open the redeem window.
- Type the code into the input field exactly as printed above.
- Press USE CODE. Amber and eggs land immediately. A second attempt on the same account is rejected even when the code is live.
How We Verified This List
Our method is on the how we verify Roblox codes page. Here, on September 11, 2026, we used:
- The live Roblox APIs for universe 2527789729 — games, votes, badges and virtual-events — for every number here. The game description carries no codes block, so the store page offers nothing to read.
- The official Prior Extinction Fandom wiki, for the code table, the case-sensitivity disclaimer and the Menu button list. We pulled its revision history rather than trusting the page: the Codes table's last content edit is January 7, 2025, so its "Valid" column is historical.
- The official Prior Extinction Discord, checked through Discord's invite API:
discord.gg/priorextinctionresolves to server "P.E.", 57,833 members on September 11, 2026, with a description word-for-word identical to the game's Roblox description. - Three unconnected code trackers, each weighted by its own last-checked stamp. Sites sharing a publisher, or repeating the same rows in the same order, count once.
Two sources we skipped: a .wiki domain posing as the official wiki, registered on August 7, 2026 through a registrar we have traced to auto-generated Roblox sites; and a second Fandom wiki that looks official but has no active editors and no real edit since 2024.
How to Get More Prior Extinction Codes
The official Discord (discord.gg/priorextinction, server "P.E.", 57,833 members on September 11, 2026) is where codes surface first. The wiki's trivia note is blunt about which are trustworthy: "Codes via Discord or by Content Creators are typically always valid."
The Roblox group Jacys Studios ROBLOX (ID 5288558, 242,086 members on September 11, 2026) carries announcements and unlocks the Citipati starter dinosaur for joining. Its group shout was empty when we read it that day.
The map itself. The official wiki states that some codes "are embedded on terrain as small, bold texts" and are single-use once found. Worth watching for while you explore the bigger biomes.
Why Aren't My Prior Extinction Codes Working?
Capitalisation. The most common cause. The wiki's code page leads with the case-sensitivity disclaimer, and both working codes end in an easily-dropped exclamation mark. Paste rather than type.
You already used it. One redemption per account, and a claimed code is rejected exactly like a dead one.
The code is genuinely dead. The six wiki "Valid" codes above — TunnelDweller, PostTV, HotSmudge, WoofWoof, JurassicUpdate, GemFix — still circulate on trackers that copy that frozen table.
Wrong game. Jacys Studios runs three Prior Extinction places — this one (6698800091), a Testing Branch, and Retro. Codes are not shared between them.
Server lag. If a freshly-posted code bounces, rejoin for a new server before writing it off.
When Are New Prior Extinction Codes Released?
There is no schedule. In the archive, codes arrive with updates and holidays — RecodeRelease! came with the Recode rollout, and the seasonal batch runs GodJul, BLCKFRDLaa, HallowenEggs! and Easter.
It is currently a drought. Both working codes were already live at our August 19, 2026 check, and the September 5, 2026 update — which shipped a run of new "WILD" dinosaur skin badges on September 4 — came and went without one.
The dev's published event calendar, read on September 11, 2026, gives the next chances: Autumn runs September 1 to November 29, 2026 (1.25x fossil and 1.25x monster boosts), Wildlife Day September 4 to 14, Fossil Day October 13 to 18, and Halloween October 30 to November 9. Halloween has carried a code before, so that is the one to watch.

Frequently Asked Questions
Yes. Re-checked on September 11, 2026, two codes work in Prior Extinction (place ID 6698800091): RecodeRelease! gives 5,000 Amber, 1 Melanistic Egg and 1 Leucistic Egg, and HaveSomeEggs! gives 2 Melanistic, 2 Leucistic, 2 Garden and 2 Retro Eggs. Both were already live on August 19, 2026, and the September 5 update added none. Codes are case-sensitive and work once per account.
On the Main Menu, not inside a match. The game opens on a splash screen of rules and latest updates; click through to the Main Menu and CODES sits in the same button column as Play, Tutorial, Mastery, Leaderboards and Shop. The official wiki lists the Codes location as "In the Main Menu", so you do not need to pick a dinosaur or join a server first.
One tracker network lists HaveSomeEggs! as expired while calling WelcomeBack!, Welcome26 and LunarFixes! active — the exact opposite of every other list. Two sites in it publish the same rows in the same order with the same reward wording, so they count once, not twice. Three unconnected sources, read on September 11, 2026, put HaveSomeEggs! in the working column.
