Arknights: Endfield Codes (January 2026) — How to Redeem and Full Rewards

Update: We checked for new Arknights: Endfield codes on January 22, 2026, but there were no changes.

Arknights: Endfield uses an in-game code system that lets you claim free Oroberyl, T-Creds, and upgrade materials during the launch period. Rewards are delivered via the in-game mailbox and each code can only be used once per account.

All current Arknights: Endfield codes

The following codes are active for the January 22–29, 2026 launch window. Each account can redeem every code once, and all of them expire at the end of that period.

Note: ENDFIELD4PC is restricted to PC clients. The other three codes can be used on any platform once the redemption feature and mailbox are unlocked.

How to redeem codes in Arknights: Endfield (in-game)

Arknights: Endfield handles all launch codes through an in-game “Exchange Code” option in the Settings menu. There is no separate web redemption site for Endfield at launch.

Step 1: Play through the opening until you can freely access the main menu. After the initial prologue (“Process: Cold Start” and early missions like “Valley Reboot” / “Break the Siege”), the full settings and mailbox systems become available.

Step 2: Open the game menu. On PC this is done with the Esc key; on mobile or console, tap or select the main menu button.

Step 3: Select Settings (the gear icon in the top-left of the menu screen).

Step 4: At the top of Settings, go to the Platform & Account tab. The icon looks like a small person silhouette.

Step 5: Find the Exchange Code row and choose the button on the right (often labeled Go or similar) to open the code entry window.

Step 6: Carefully type or paste one of the codes from the table above into the field, matching the uppercase letters exactly, then confirm the redemption. Each code can be claimed once per account.

Step 7: After a successful redemption, open your in-game Mail to actually receive the rewards. Mail appears as an envelope icon in the HUD and is also listed in the main menu once unlocked.

Step 8: Claim the attached items from each mail message. Rewards generally remain in your mailbox for about 30 days; unclaimed mail expires after that.

Tip: If the Exchange Code button does nothing or the Mail icon has not appeared yet, progress the main story a little further until the game introduces the mailbox and headhunting systems.

How to redeem classic Arknights (tower defense) codes

For the original Arknights tower defense game, code redemption uses a separate web page rather than the in-game menu.

Step 1: Open Arknights on your device and go to the main lobby screen. Locate your UID, which is displayed underneath your in-game nickname.

Step 2: On a browser, go to the official global redemption page at https://arknights.global/gift.

Step 3: Enter your Arknights UID into the UID field exactly as it appears in-game.

Step 4: Enter a valid Arknights gift code in the code field, then confirm. Each code can only be used once per account, and expired codes are rejected.

Step 5: Return to Arknights and open your in-game mailbox. The rewards from the redeemed code arrive there; claim them before the mail expires.

The web page also lists basic conditions such as one-time use per account, the need for a correct UID, and the fact that expired codes cannot be used.

Why a code might not work

If an Arknights: Endfield or Arknights code fails, the most common reasons are:

• Expired campaign window: All current Endfield launch codes stop working after late January 29, 2026 (server time).
• Already redeemed: Every code is limited to one redemption per account. Trying again on the same account will fail even if the code itself is still active.
• Typo or extra characters: Codes are case-sensitive. Extra spaces before or after the text, swapped letters, or mistyped numbers will cause an error.
• Feature not yet unlocked: In Endfield, the Exchange Code menu and Mail system only function properly after early story missions are cleared.
• Platform restriction: ENDFIELD4PC only works on the PC client. Attempting to use it on other platforms will not succeed.

When a redemption fails, double-check the spelling, confirm that you have not used the same code on that account already, and ensure you are still within the active event period.

Oroberyl from these launch codes can be saved for later banners or spent immediately on the starting rate-up characters, while T-Creds and Combat Records give an early boost to base development and operator leveling. Redeem everything during the launch window so none of the rewards are lost to expiry.
