How to Redeem Arknights Codes
Arknights holds 0 confirmed codes as of 25 October 2026, with 8 more sitting in pending because only one tracker carries them. The warning that matters: the redeem box is not where most guides put it, and there is no success message once a code lands.
Where is the redeem button?
Open Shop, go to the Gift tab, paste the code and press Confirm.
Full step-by-step guide
- 1 Load into the game and let the lobby finish rendering. The form needs your Game ID and Zone ID, plus a verification code that the publisher mails to your in-game inbox — skip that second step and every code fails with what looks like an invalid-code error.
- 2 Open Shop. it is the phone icon in the corner, and a handset appears with the redeem button on it.
- 3 Work inside the Gift tab. The field is at the very bottom of that panel.
- 4 Paste instead of typing. The strings are uppercase with digits in the middle, and a wrong capital is rejected without any message.
- 5 Press Confirm and check the reward lands in your in-game mailbox, not straight into your balance.. Success shows up as a mail in your in-game inbox — there may be no on-page confirmation at all.
- 6 Redeem the gem codes before the cash codes. Cash buys gear you can use immediately; gems are the only route into the power pool.
- 7 If a confirmed code fails twice, rejoin. Some codes are scoped to one region or event campaign, so a valid code can still refuse on your account.

Codes not working? Try these fixes
A code from the main table says invalid — is it dead?
Check the pending block first. If it is in the main table, at least two trackers confirm it, so the usual cause is a typo, a trailing space, or a server on an older build. Try a fresh server before declaring it dead.
Can I redeem the same code twice on one account?
No. Each code is one claim per account, so a string that suddenly refuses on your main may simply have been claimed there weeks ago. Check an alt before calling it expired.
Why is the confirmed list so short?
The table is short because nearly every code is a milestone code — visits, likes, members. Once the milestone passes the code retires and the next one replaces it, so the list rotates rather than grows.
Do codes expire without notice?
Yes, and this game rarely announces it. Treat anything older than a month as a guess rather than a fact.
