Arknights: Endfield hands out free codes every so often, and redeeming them is one of the easiest ways to stock up on T-creds, Oroberyl, and combat items without grinding for them. You’ll want to punch these in as soon as you can, since some codes only stick around for a limited stretch before HYPERGRYPH shuts them off.

How to redeem codes in Arknights: Endfield
There’s no website where you can punch in these codes. Redemption happens entirely inside the game, and you won’t even see the option until you’ve cleared the early tutorial and unlocked Mail during the Break the Siege main mission. Once you’re past that point, here’s what to do.

A successful redemption won’t drop items straight into your bag. Instead, open the Mail icon and hit Claim All to pull everything into your inventory. Rewards sit in your mailbox for 30 days before they disappear, so don’t let a code go unclaimed for too long.

How to get more Arknights: Endfield codes
New codes usually show up around major updates, anniversaries, or livestreams, and the team behind the game tends to post them on its official social accounts first. Joining the official Arknights: Endfield Discord server is a solid way to catch new codes as soon as they’re shared, since the community there often flags them the moment they go live. There’s no set schedule for how often codes drop, so check back periodically rather than expecting a fixed cadence.
Why didn’t my code work?
Codes are case-sensitive, so double-check every letter and number before hitting Confirm. If a code has already expired, the game won’t accept it no matter how carefully you type it in, and you’ll need to wait for the Mail feature to reflect a claim if it seems stuck.
Keep an eye on your Mail tab after redeeming, since that confirmation and the Claim All button are your signal that a code actually went through.
