Looking for the latest working Arknights: Endfield codes? This guide tracks active exchange codes, free Homecoming and upcoming version rewards, expired codes, and the exact steps required to claim each reward.
Last checked: August 31, 2026. Four exchange codes are currently reported as available, including the newer reward code AKENDFIELDSUB. The previous Homecoming Special Program code ENDFIELDRENEW expired on August 30, while the separate Companionship Celebration Special Program mail had an earlier July 24 login eligibility deadline.
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.

Homecoming Mail Rewards and Compensation
Arknights: Endfield has been running the Homecoming Core Chapter version, but the next major update is now scheduled to launch as Dreamscape of Wind and Snow on September 2, 2026. The earlier Homecoming reward package announced after the July 10 Companionship Celebration Special Program was an automatic in-game mail reward rather than an exchange code, and its login eligibility window has already ended. The official site now lists the September 2 version update as the next major release. :contentReference[oaicite:2]{index=2}
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). Mail already delivered remains valid for 14 days from delivery. |
The reward was issued beginning on July 10, 2026 at 20:40 (UTC+8). New accounts could no longer qualify after the July 24 login deadline. Eligible players who already received the message should check its displayed expiration date and collect the attachments before the 14-day mail period ends.
Homecoming Update Compensation
The Homecoming update included two separate compensation mails:
| Compensation | Reward | Eligibility |
|---|---|---|
| Update and Maintenance Compensation | Oroberyl ×900 | Character created before the Homecoming update |
| Bug Fix Compensation | Oroberyl ×900 | Character created before the Homecoming update |
These compensation mails were available during the Homecoming version period and should no longer be presented as a new September reward source after the September 2 version transition. The current official site now points to Dreamscape of Wind and Snow as the upcoming version. :contentReference[oaicite:3]{index=3}
Dreamscape of Wind and Snow Celebration Mail
The latest Version 1.5 preview did not introduce another universal exchange code. Instead, a separate celebration mail is being distributed to eligible players around the Dreamscape of Wind and Snow preview. Current reporting lists 1,000 Oroberyl, 10,000 T-Creds, 8 Elementary Cognitive Carriers, and 4 Arms INSP Sets, with the login eligibility period running from August 21, 2026 at 19:30 (UTC+8) through September 4, 2026 at 19:30 (UTC+8). The mail itself then follows its own claim period. :contentReference[oaicite:4]{index=4}
This reward is delivered by mail rather than through the Exchange Code field, so check your Mailbox as well as the active code list when the September version begins.
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. The official WhatsApp / Messenger event also states that the issued code must be used before its September 9 deadline. :contentReference[oaicite:5]{index=5}
