Redeeming codes in Arknights: Endfield is straightforward, but there are a few prerequisites you need to meet first. Follow this step-by-step guide to claim your rewards without any issues.

Prerequisites

Once you've unlocked the Mail feature, you're ready to redeem codes. Here's how:

Pro Tip:If you've tried everything and the code still doesn't work, try logging out and back in, or wait a few minutes and retry. Server congestion during new code releases can sometimes cause temporary issues.

The following codes were previously active but have since expired. I've included them for reference so you know what types of codes to expect in the future:

These launch celebration codes were available from January 22-29, 2026, and provided substantial rewards to early players. While they can no longer be redeemed, they demonstrate the types of codes Hypergryph releases during major events.

Frequently Asked Questions（FAQ）

Q: How often are new codes released?
A: New codes typically coincide with major updates, version livestreams, special events, and milestone celebrations. On average, expect 2-4 new codes per month during active periods.

Q: Can I use the same code multiple times?
A: No, each redeem code can only be used once per account. Attempting to redeem a code you've already used will result in an error message.

Q: Do codes work on all platforms?
A: Most codes work across all platforms (PC, iOS, Android). However, some codes like ENDFIELD4PC are platform-specific. Always check the code description for platform restrictions.

Q: How long do I have to claim mail rewards?
A: Mail rewards expire after 30 days from the date they were sent. Make sure to claim your rewards promptly to avoid losing them.

Q: What's the difference between Oroberyl and T-Creds?
A: Oroberyl is the premium gacha currency used for pulling characters on banners. T-Creds are the standard in-game currency used for base development, upgrades, and various in-game purchases.

Q: Can I redeem codes before completing the tutorial?
A: No, the code redemption feature is locked until you complete the early tutorial missions and unlock the Mail system. This typically happens after completing the "Break the Siege" mission.

Q: Are there region-locked codes?
A: Some codes may be region-specific, particularly those distributed through platform-specific events (like Bilibili or TapTap exclusive codes). Most general codes work globally.

Conclusion

Arknights: Endfield redeem codes represent one of the easiest ways to accelerate your progress on Talos-II without spending real money. From my personal experience, the Oroberyl and upgrade materials obtained through these codes made a significant difference in my early game progression, allowing me to pull for key Operators and upgrade my base facilities much faster than I would have otherwise.
