Arknights Endfield Codes Guide: Active & Expired

Arknights Endfield codes are the cheapest way to stockpile gacha currency and level-up materials without spending, and the redemption window is usually short. Hypergryph's semi-open-world RPG is live on Talos-II, and the code exchange is available almost immediately after the opening cutscene wraps.

That low barrier matters. Unlike most gacha titles, Endfield does not gate code redemption behind story progress, so a fresh account can claim rewards on day one. For the wider picture on patches, banners, and progression, bookmark our Arknights Endfield news and guides hub.

Expired codes cannot be redeemed, and Hypergryph does not restore missed rewards. If you see one of these circulating on social media, skip it.

How to Redeem Arknights Endfield Codes

Redemption takes under a minute once you know the path. There is no story gate, so you can do this on a brand-new account.

1. Press Esc to open the pause menu.
2. Go to Settings.
3. Navigate to the Platform & Account tab.
4. Click Go beside Exchange Code.
5. Enter an active code from the list above.
6. Hit Confirm.
7. Press H in-game to open your mailbox.
8. Claim your rewards.

Step eight is the one players skip. Redeeming a code does not deposit items into your inventory automatically; the rewards sit in system mail until you claim them.

Troubleshooting Common Code Errors

Most failed redemptions come down to three causes.

• Code already used: each code is typically one redemption per account. If you play on multiple devices under one account, the second attempt will fail.
• Code expired: codes have short lifespans, often tied to livestreams or update windows. There is no grace period.
• Typo or case sensitivity: copy codes exactly. Extra spaces at the start or end are a frequent culprit when pasting from social posts.

If a code is valid but nothing appears in your inventory, open the mailbox with H and claim the attachment manually.

Mailbox Expiry: The Rule Most Players Miss

System mail in Arknights Endfield automatically expires 30 days after it lands in your inbox, regardless of whether it contains unclaimed attachments. That applies to code rewards, event compensation, and maintenance mail alike.

Practical takeaway: redeem and claim on the same day. If you are stockpiling currency for an upcoming banner, do not leave rewards sitting in mail while you decide. For banner timing and pull planning, see our Arknights: Endfield banner guide.

How to Get More Arknights Endfield Codes

The fastest method is to bookmark this page. We monitor official channels so you do not have to.

If you prefer to track sources yourself, the two primary channels are the official X/Twitter account and the official Discord server. Codes are most likely to appear during:

• Livestreams and pre-update broadcasts
• Major patch launches, such as the 0.5.1 At the Wake of Spring update
• Content creator collaborations
• Major holidays and promotional events

For context on how update cadence affects reward timing, our breakdown of the Wake of Spring update covers the patch's progression and event changes.

FAQ

Do codes expire?

Yes. Every code has a redemption window, and expired codes cannot be reactivated. The four codes listed above are already dead.

Can I redeem the same code on multiple accounts?

Typically one redemption per account. Running alt accounts is a separate redemption, not a duplicate.

Do code rewards affect pity?

Not stated in official materials. Currency from codes feeds the same pull economy as any other source, so treat it as standard gacha currency when planning.

Is there a level requirement?

No. Redemption unlocks right after the opening cutscene, with no story mission gate.

What if my reward never arrives?

Check the mailbox with H first. If the code was accepted but mail is empty, the code may have expired between entry and confirmation.

Next Steps

With no active codes live right now, the practical move is to claim anything still sitting in your mailbox before the 30-day timer runs out, then hold your currency for the next limited banner. Our March 2026 codes roundup tracks the same redemption flow if you want a second reference point.

When new codes drop, they will appear at the top of this page. Redeem, claim, and spend with a plan.
