Arknights: Endfield Codes (May 2026)

Update: We found 1 new Arknights: Endfield code on May 24, 2026 and added it to the list.

Arknights: Endfield currently has a small set of redeemable codes that grant currency and upgrade materials. Rewards are delivered through the in-game Mail system after redemption, and each code can be used once per account.

Working Arknights: Endfield codes

ZAU2SYXHWX5L4ZH NEW — 5,000 T-Creds and 10 Arms INSP Kit
ENDFIELDGIFT — 150 Oroberyl, 10,000 T-Creds, 20 Intermediate Combat Record, and 20 Arms INSP Kit
ENDFIELD4PC — 13,000 T-Creds, 2 Advanced Combat Record, and 2 Arms INSP Kit (PC only)

Version 1.3 mail rewards

Alongside the current code pool, a Version 1.3 mail reward was issued in-game on May 22, 2026 at 20:00 (UTC+8). That mail includes 1,000 Oroberyl, 10,000 T-Creds, 8 Elementary Cognitive Carrier, and 4 Arms INSP Set.

The mail can be claimed after you unlock the Mail feature, and that specific mail stays valid for 14 days.

How to redeem Arknights: Endfield codes

Launch Arknights: Endfield and load into the game. Codes are redeemed in-game rather than from a separate web portal.

Open the main menu, then enter Settings. On PC, this can be done with Esc.

Go to Platform & Account. Select Exchange Code.

Enter the code exactly as shown, then confirm the redemption. If it works, the reward is sent to your in-game mailbox.

Open Mail and claim the attached items. Standard reward mail expires after 30 days, so it is best to collect it promptly.

When redemption becomes available

You need to progress far enough to unlock the Mail system before you can collect code rewards. One confirmed requirement is completing the tutorial and unlocking Mail during the Break the Siege Main Mission.

Another confirmed progression point tied to in-game redemption is completion of Valley Reboot. Once the Exchange Code option is visible and Mail is unlocked, redemption is ready to use.

Expired Arknights: Endfield codes

ALLFIELD — Expired
RETURNOFALL — Expired

What the active codes give you

The current rewards focus on basic progression resources. T-Creds cover routine spending, while Arms INSP Kit and Combat Record items help with upgrades and leveling. Oroberyl is included through ENDFIELDGIFT and through the recent in-game mail reward.

For most accounts, the best order is simple. Redeem the universal codes first, then use ENDFIELD4PC if you play on PC.

If new codes are added, the active list will change before the expired list does, so the working set above is the one to use first.
