Update: We checked for new Arknights: Endfield codes on February 10, 2026, but there were no changes.
Arknights: Endfield uses limited-time redemption codes to hand out extra currency and materials. Only a small number are active in February 2026, and some early launch codes have already expired.

Requirements to redeem Arknights: Endfield codes
Codes can only be redeemed once basic progression is complete. The following conditions must be met before the Exchange Code option appears and rewards can be claimed:
- You must finish the initial prologue/tutorial so that you can freely control your character.
- You must unlock the Mail system by progressing the main story through the mission Break the Siege.
- You must be logged into your save in-game; codes cannot be redeemed from the login screen.
- For
ENDFIELD4PC, you must be playing on PC when entering the code.
Once these conditions are satisfied, all working codes can be entered from the in-game settings and their rewards collected from Mail.
How to redeem Arknights: Endfield codes in-game
Step 1: Start Arknights: Endfield and load your save so you are controlling your character. Codes cannot be redeemed from the title or login screen.
Step 2: Open the pause menu. On PC, press the Esc key. On controller, press the Options button. This opens the main pause overlay.
Step 3: Select the cog icon in the top-left corner of the screen to open Settings. If you are using the Protosync Menu later in the game, use the same cog icon there.
Step 4: In Settings, switch to the Platform & Account tab. It is indicated by a small human-shaped icon.
Step 5: Choose the Exchange Code option. A text field appears where you can type or paste a code such as ENDFIELDGIFT or ENDFIELD4PC.
Step 6: Confirm the entry. If the code is valid for your account and platform, a Redemption Success message appears and the reward is sent to your Mail.
Step 7: Return to the main menu overlay and open the Mail icon (envelope symbol). Locate the new message containing the redemption reward and select the claim option (for example, Claim All) to move the items into your inventory.
How to confirm that a code worked
A successful redemption always shows two clear indicators:
- A confirmation message on the Exchange Code screen stating that the redemption succeeded.
- A new mail in your inbox containing the specific reward bundle for that code.
If neither appears, the code did not apply and the reason is usually one of the common cases below.
Why an Arknights: Endfield code may not work
When a code fails, the cause is almost always one of these conditions:
- Code expired: Launch codes
ALLFIELDandRETURNOFALLwere only valid until January 29, 2026 and now return an error. - Already used on this account: Each code can generally be redeemed once per account. Attempting to use it again will fail.
- Platform restriction:
ENDFIELD4PCis limited to PC. Accounts that started on mobile may be treated as ineligible even when logged in from a PC client. - Progress not sufficient: If the tutorial or the mission unlocking Mail has not been completed, the Mail system or Exchange Code option is unavailable.
- Spelling issue: While codes are not case-sensitive, any difference in letters or numbers will invalidate them. Ensure there are no extra spaces before or after the text.
- Temporary server problem: On rare occasions, redemption can fail due to network or server issues. Retrying after a short time usually resolves this.
How long Arknights: Endfield mail rewards stay claimable
Rewards from codes and other system messages are delivered to your in-game Mail. Messages remain in the inbox for a limited time only. Unclaimed mail is automatically deleted after 30 days, and any attached rewards are lost when the message expires.
To avoid losing items or currency from codes, claim all Mail rewards promptly after a successful redemption.
