Zenless Zone Zero hands out free Polychrome, Denny, W-Engine materials, and Investigator Logs through redemption codes that HoYoverse rotates alongside version updates, livestreams, and collaborations. Below is the current list of working codes for the game, along with how to redeem them before they expire.
Working Zenless Zone Zero codes
Enter these exactly as written, since they are case-sensitive. Rewards land in your in-game mailbox shortly after redemption.

Some of these codes share a single reward pool. If a code claims to be redeemed already even though you never entered it, that usually means another code in the same batch already delivered the reward to your account.
How to redeem codes in Zenless Zone Zero
Your account needs to reach Inter-Knot Level 5 and clear the early tutorial mission “The Hare and the Proxy” before the redemption menu accepts any code. Once that’s done, you can redeem codes either inside the game or on the official website.

A successful redemption shows a confirmation message on screen, and the reward mail typically appears within a few minutes.
Expired Zenless Zone Zero codes

New codes tend to surface around major version drops and livestream broadcasts, so it’s worth revisiting the working list above whenever a new update rolls out rather than hunting for codes that have already run their course.
