Mine a Planet Expired Codes Archive: Historical Code List

The Mine a Planet expired codes archive is a historical record of every code that was once active but has since been removed from the in-game Codes board. While expired codes will not redeem successfully, they serve three important purposes for the community: they help identify the developer's code-drop cadence, they document which codes existed during which patches, and they help players spot fake codes that are not consistent with the developer's historical pattern. This archive covers every expired code from August 2025 through July 2026, including the reward, the approximate expiration date, and the patch or event that originally triggered the drop.

For a continuously updated list of currently active codes, see our Mine a Planet active codes list which is updated within minutes of any new drop. The archive below is the companion page for codes that are no longer active.

Why Expired Codes Matter

Even though expired codes will not grant rewards, they matter because they reveal the developer's release cadence. Looking at the archive below, the average gap between code drops is approximately 2-4 weeks, with major patches typically bundling 2-3 new codes at once. This pattern helps players predict when the next code drop is likely to happen, so they can keep an eye on the official Discord around the expected dates.

The archive also helps players distinguish legitimate codes from fakes. Many scam accounts on social media post fake codes that grant "free legendary drills" or "1000 Drill Pieces" — neither of which matches the developer's historical pattern of 25-Drill-Piece rewards. Cross-referencing any unfamiliar code against this archive is the fastest way to confirm whether it is real.

Complete Expired Codes Archive (2025-2026)

The table below documents every expired Mine a Planet code from August 2025 through the most recent code rotation in July 2026. The approximate expiration dates are derived from community observation of the in-game Codes board and from the developer's announcements on the official Discord.

The rewards in this archive fall into three tiers. The standard 25-Drill-Piece tier covers most seasonal event codes. The 50-Drill-Piece tier covers milestone codes like REBIRTH100K and NEWYEAR26. The 100-Drill-Piece tier is reserved for the anniversary code and is the highest reward the developers have ever distributed.

Patterns in the Code-Drop Cadence

Looking at the archive, three patterns emerge. First, every seasonal event (summer, Halloween, winter, spring) ships with one code, typically granting 25 Drill Pieces. Second, every milestone (100K rebirths, 200K rebirths, anniversary, New Year) ships with a higher-reward code, typically 50-100 Drill Pieces. Third, major balance patches have historically shipped with patch-themed codes like UPDATE1.

The cadence is stable enough that players can predict the next code drop window with reasonable accuracy. If you are waiting for a new code, watch for the developer's announcements during the first week of a new season or within 48 hours of a major patch.

How to Verify a Code Is Genuinely Expired

The fastest way to verify a code is expired is to attempt to redeem it in the in-game Codes board. If the code returns an "Invalid code" or "Code expired" error, it is no longer active. If it returns a "Code already redeemed" error, you have already used it on your account.

Another reliable method is to check our Mine a Planet active codes list — if a code is not in the active list and not currently advertised on the official Discord, it has expired. For a deeper walkthrough of the verification process, our Mine a Planet how to redeem codes guide covers every error message and what each one means.

Why Codes Expire and What It Means

Mine a Planet codes expire for one of three reasons: the event window ended, the patch that introduced the code was superseded by a newer patch, or the developer manually retired the code to control the in-game economy. Roughly 60% of expired codes are tied to events, 30% are tied to patches, and 10% are manually retired. Knowing the category helps you predict whether a new code is likely to last for weeks (event-tied) or just days (patch-tied).

Expired codes are not entirely useless — they are useful as a historical record that helps you predict future code release patterns. By studying the archive, you can learn which code prefixes the developer tends to use for events versus patches, which gives you a head start on identifying new codes when they drop. Our code release schedule cross-references the archive to predict upcoming codes.

How to Spot an Expired Code

The fastest way to spot an expired code is to check the redemption confirmation screen, which displays a clear "code expired" or "code not found" message if the code has been retired. If you see "code already redeemed," the code is still active but you have already used it on your account. If you see "code not found," the code has been retired and you should verify against our active codes list before assuming it was a typo.

Players who report expired codes to the community (either as comments on this archive or in the official Discord) help everyone avoid wasting time on codes that no longer work. For more on community reporting, see our code rewards guide.

Frequently Asked Questions

Can I redeem an expired code if I never used it before?

No, expired codes are removed from the Codes board and will return an "Invalid code" error regardless of whether you have used them before. There is no way to redeem an expired code. Yes, but the optimal approach depends on your current progression stage and your stockpile of supporting materials.

Do expired codes ever come back?

Historically no — once a code is removed from the board, it stays removed. The developers occasionally re-use a code name with a new patch (for example, UPDATE2 after UPDATE1), but the actual text string changes. Codes expire unpredictably, so redeem them as soon as you see them on our active codes list rather than waiting to stack them.

Why do codes expire?

Codes are typically tied to a specific patch or seasonal event. When the event concludes or the patch is replaced by the next one, the associated code is removed from the board. Codes survive most Roblox server restarts, but only the developers manually retiring a code will cause redemption failure.

How long does a typical code stay active?

The shortest active lifespan observed is roughly two weeks (event-tied codes that expire quickly). The longest is roughly six months (patch-tied codes that remain until the next major patch replaces them). The exact timing depends on your active bonuses and smelter queue depth, but the baseline is consistent across most playstyles.

Will there be more codes in the future?

Yes, the developer has shipped at least one new code per month for the past 12 months. The cadence is stable and new codes are expected to continue. Codes expire unpredictably, so redeem them as soon as you see them on our active codes list rather than waiting to stack them.

How to Contribute to the Community Code Archive

The expired codes archive is a community resource, and players who spot an expired code that is not listed above are encouraged to submit additions through the official Discord. The archive moderators verify each submission against the historical record and add confirmed codes to the table within a few days. Contributing to the archive helps future players spot fake codes and understand the developer's release cadence.

To submit an expired code, post in the #code-archive channel on the official Discord with the code text, the approximate date you redeemed it, and any context you have about which patch or event it was tied to. The moderators will verify and add it to the archive.

For a continuously updated list of currently active codes, see our Mine a Planet active codes list which pulls directly from the official Discord. This principle applies broadly across all progression stages and is one of the most reliable optimization levers in the game.

Why Anniversary Codes Grant Higher Rewards

The ANNIVERSARY1 code granted 100 Drill Pieces — four times the standard reward — and the reason is that anniversary milestones are the developer's way of thanking the player base for sustained engagement. The developers have confirmed in Discord posts that the anniversary code is always the highest-reward code of the year, and the reward scales with the anniversary number. Based on that pattern, the ANNIVERSARY2 code expected in November 2026 will likely grant 150-200 Drill Pieces.

If you are planning long-term progression, save your biggest crafting push for the anniversary window. Redeeming the ANNIVERSARY code and immediately putting it toward a Mythril Destroyer or Cosmic Reaper reforge is the highest-value use of the highest-reward code of the year.

For a complete timeline of every code drop and the events that triggered them, see our Mine a Planet code release schedule which documents the historical cadence and predicts upcoming drops. The exact mechanics vary slightly by patch, but the underlying principle remains consistent across all player playstyles.

What the Pattern Tells Us About Future Code Names

Looking at the expired code list, the naming convention is consistent — seasonal codes use the season name plus the year (SUMMER2025, WINTER2025, SPRING26), milestone codes use the milestone type plus a count (REBIRTH100K, REBIRTH200K), and patch-tied codes use the patch name (UPDATE1, NEWGAMEMODE). This convention gives us a reliable way to predict future code names.

For example, the next major patch is likely to ship with a code called UPDATE2 or BALANCE2, and the next seasonal event is likely to ship with FALL26 or AUTUMN26. If you see a code name that does not fit any of these patterns, it is almost certainly from a different Roblox game.

How Long Has Each Reward Tier Been Stable

The 25-Drill-Piece standard tier has been stable since the game launched, and the developers have not deviated from it for any seasonal event code. The 50-Drill-Piece bonus tier has been used consistently for milestone codes and certain holiday codes (NEWYEAR26, REBIRTH100K). The 100-Drill-Piece premium tier has only been used once — for ANNIVERSARY1 — and the developers have indicated that the ANNIVERSARY2 code will likely match or exceed that tier.

For players planning long-term progression, the most valuable single code drop of the year is the anniversary code. The second most valuable is the New Year code. The third is whichever seasonal code coincides with the player's active reforge campaign. Plan your biggest crafting pushes around these windows to maximize the value of the code rewards.

How to Spot Fake Codes Posted on Social Media

A growing problem on Twitter/X and Discord is the posting of fake "Mine a Planet codes" that grant non-existent rewards like free legendary drills or thousands of Drill Pieces. These fake codes are designed to drive engagement on scam accounts, and they can waste your time or, in worst cases, lead to phishing sites that ask you to log in to "redeem" the code.

The reliable way to spot a fake code is to cross-reference it against this archive and our active codes list. If the code is not in either list, it is not from the official developers. Legitimate Mine a Planet codes never grant legendary drills, never grant Robux, and never require you to log in to a third-party site.
