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.
Three exchange codes remain available in October: ZAU2SYXHWX5L4ZH, ENDFIELDGIFT, and the PC-only ENDFIELD4PC. The limited subscription code AKENDFIELDSUB reached its published September 9 deadline and has been moved to the expired section.
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 Arknights: Endfield Codes (October 2026)
| Exchange Code | Rewards | Availability |
|---|---|---|
ZAU2SYXHWX5L4ZH |
T-Creds ×5,000, Arms INSP Kit ×10 | Still reported active by multiple current code lists; no public expiration date announced |
ENDFIELDGIFT |
Oroberyl ×150, T-Creds ×10,000, Intermediate Combat Record ×20, Arms INSP Kit ×20 | Still reported active by current working-code lists; no public expiration date announced |
ENDFIELD4PC |
T-Creds ×13,000, Advanced Combat Record ×2, Arms INSP Kit ×2 | Still reported active; must be entered through the PC client |
Important: ENDFIELD4PC must be entered through the PC version. Mobile and PlayStation players can still claim the other available codes. AKENDFIELDSUB is no longer active because the official WhatsApp / Messenger subscription campaign ended on September 9, 2026.
The current codes provide a combined total of 150 Oroberyl and 28,000 T-Creds for PC players who can redeem all three available codes. Players without access to the PC client can receive up to 150 Oroberyl and 15,000 T-Creds, plus the included progression materials.
October Version Rewards and Compensation
Arknights: Endfield is currently running the Dreamscape of Wind and Snow version, which launched after maintenance on September 2, 2026. Several free rewards remain available during the version, while a new group of sign-in and event activities opens from October 1.
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.
Dreamscape of Wind and Snow Update Compensation
The September 2 version transition included two compensation mails for eligible accounts. Both are separate from the current exchange codes and remain claimable until the next version update and maintenance:
| Compensation | Reward | Eligibility |
|---|---|---|
| Dreamscape of Wind and Snow Update & Maintenance Compensation | Oroberyl ×900 | Create a character before the September 2 version update; sent after maintenance and available until the next version update and maintenance |
| Dreamscape of Wind and Snow Bug Fix Compensation | Oroberyl ×900 | Same eligibility requirement; delivered through a separate in-game mail and available until the next version update and maintenance |
Eligible accounts can therefore receive up to 1,800 Oroberyl from the two Dreamscape compensation mails. Check the in-game Mailbox and claim them before the next version maintenance begins.
For the previous version's banner information, see the Arknights: Endfield Homecoming banner schedule.
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.

October adds several more free reward sources without requiring a code, including Ridgeline Flows of Autumn, Runners' Steeplechase, OrbiPom! MERGE!, and Monumental Etching: Shadow Marked.
