Looking for the latest working Arknights: Endfield codes? This guide tracks active exchange codes, current version rewards, expired codes, and the exact steps required to claim each reward.
As of October 27, 2026, the latest officially announced public code is ENDFIELDSTEAM, available through November 25. Three older codes—ZAU2SYXHWX5L4ZH, ENDFIELDGIFT, and the PC-only ENDFIELD4PC—still appear on some current lists, but recent trackers do not agree on their status. AKENDFIELDSUB expired on September 9.
Codes and event mails do not always share the same expiration date. Copy each code exactly as displayed, redeem it promptly, and collect every attached reward before the individual mail expires.
Active and Reported Arknights: Endfield Codes (October 2026)
| Exchange Code | Rewards | Availability |
|---|---|---|
ENDFIELDSTEAM NEW |
T-Creds ×8,000, Elementary Cognitive Carrier ×2, Arms INSP Set ×2, Special Commemorative Portrait Frame ×1 | Official Steam wishlist milestone code; redeem by November 25, 2026. Asia: 23:59 (UTC+8); Americas / Europe: 10:59 (UTC-5) |
ZAU2SYXHWX5L4ZH |
T-Creds ×5,000, Arms INSP Kit ×10 | Reported active by some current lists, but recent trackers disagree; no official expiration date announced |
ENDFIELDGIFT |
Oroberyl ×150, T-Creds ×10,000, Intermediate Combat Record ×20, Arms INSP Kit ×20 | Reported active by some current lists, but recent trackers disagree; no official expiration date announced |
ENDFIELD4PC |
T-Creds ×13,000, Advanced Combat Record ×2, Arms INSP Kit ×2 | Reported active by some current lists, but recent trackers disagree; PC client only |
Important: ENDFIELD4PC must be entered through the PC client. ENDFIELDSTEAM is available on the supported servers until November 25, 2026; the other listed codes have no publicly announced expiration date. AKENDFIELDSUB is expired because the official WhatsApp / Messenger subscription campaign ended on September 9, 2026.
If all three older codes remain redeemable, PC players could receive a combined total of 150 Oroberyl and 36,000 T-Creds from all four codes, plus the listed progression materials and portrait frame. Mobile and PlayStation players could receive up to 150 Oroberyl and 23,000 T-Creds from the three codes available to them. These totals are conditional because recent trackers do not consistently confirm the older codes.
October Version Rewards and Compensation
Arknights: Endfield is currently running the Sanctuary of Ink version, which launched after maintenance on October 15, 2026. Its new events and reward activities are rolling out through October and early November.
Ended: Companionship Celebration Special Program Mail
| Requirement | Rewards | Deadline |
|---|---|---|
| Log in and unlock the Mail feature | Oroberyl ×2,000, T-Creds ×12,000, Elementary Cognitive Carrier ×10, Arms INSP Kit ×10, Protohedron ×10, Mark of Perseverance ×2 |
Login eligibility ended July 24, 2026 at 20:40 (UTC+8). Previously delivered mail was valid for 14 days from delivery. |
The reward was issued beginning on July 10, 2026 at 20:40 (UTC+8). New accounts can no longer qualify, and the 14-day claim period for previously delivered mail has also passed for accounts that received it during the original distribution window.
Ended: Dreamscape of Wind and Snow Update Compensation
The September 2 version transition included two compensation mails for eligible accounts. Both were separate from the exchange codes and were claimable only until the next version update and maintenance. That claim window ended with the Sanctuary of Ink update on October 15, 2026:
| Compensation | Reward | Eligibility |
|---|---|---|
| Dreamscape of Wind and Snow Update & Maintenance Compensation | Oroberyl ×900 | Create a character before the September 2 version update; claim period ended with the Sanctuary of Ink update and maintenance on October 15, 2026 |
| Dreamscape of Wind and Snow Bug Fix Compensation | Oroberyl ×900 | Same eligibility requirement; delivered through a separate in-game mail; claim period ended with the Sanctuary of Ink update and maintenance on October 15, 2026 |
Eligible accounts could receive up to 1,800 Oroberyl from the two Dreamscape compensation mails. Their claim period ended with the Sanctuary of Ink update and maintenance on October 15, 2026, so these mails are no longer available.

How to Redeem Codes in Arknights: Endfield
Arknights: Endfield exchange codes are redeemed through the in-game Settings menu. There is currently no separate official public web redemption page for standard codes.
What You Need to Unlock First
Complete the early Process: Cold Start prologue and continue until you wake up aboard the Dijiang. Once the regular menu becomes available, you should be able to access the Exchange Code option.
The Mailbox becomes available later, after completing the Break the Siege main mission and securing the Hub Base. You may be able to enter a code before this point, but you cannot collect the delivered reward until Mail is unlocked.
Redemption Steps
- Launch Arknights: Endfield and load the character that should receive the reward.
- Open the main menu by pressing ESC on PC or using the corresponding menu button on your platform.
- Select the gear icon to open Settings.
- Open the Platform & Account tab.
- Find Exchange Code and select the button beside it.
- Enter or paste the code exactly as displayed in the active-code table.
- Confirm the exchange.
- Open the in-game Mailbox and claim the attached rewards.
Each exchange code can normally be used only once per game account. Switching devices does not reset a code that has already been claimed.

What is AKENDFIELDSUB?
AKENDFIELDSUB was the 100-Oroberyl code connected to the official WhatsApp / Messenger subscription promotion. The campaign ended on September 9, 2026 at 23:59 (UTC+8), so the code is now expired.
