All Active Zenless Zone Zero Codes

Updated: October 12, 2026. These Zenless Zone Zero codes are the current picks to try for free Polychrome, Denny and upgrade materials. HoYoverse can turn a code off without notice, so claim them before heading back into New Eridu.

*Rewards can vary by region or availability. The redemption preview and your in-game Mail are the final word on what your account receives.

What to do before entering a code

Make sure you are signed into the right HoYoverse account and know which server holds your main Proxy. The web form asks you to choose both the server and character, so it is possible to send a valid claim to an alt by mistake. In-game redemption avoids that server-selection step, although it still requires the early progression unlock.

Do not leave a limited campaign code until the next session. Version livestream codes tend to be the biggest giveaways, but they also have the shortest lifespan. The expired JRNY2SKY code is a useful reminder that a code can disappear days before a monthly guide is refreshed.

How to redeem Zenless Zone Zero codes

You need to progress through the early story until code redemption unlocks, then reach Inter-Knot Level 5.

1. Open the in-game menu while in a playable area.
2. Select More, then Redemption Code.
3. Paste a code exactly as shown and choose Redeem.
4. Open your in-game Mail to collect the rewards.

You can also use HoYoverse’s official ZZZ redemption centre. Sign in, select the correct server and character, then submit the code. The items still arrive through in-game Mail.

Why a ZZZ code may not work

Codes are one use per character and can expire, reach a claim limit or be limited to a campaign or region. Double-check the server and avoid spaces when pasting. If a code says it has already been redeemed, it normally means that character has already claimed it.

Recently expired code

JRNY2SKY, the Version 3.3 livestream code worth 300 Polychrome, 2 Senior Investigator Logs, 3 W-Engine Energy Modules and 30,000 Denny, expired at 23:59 (UTC+8) on October 11, 2026, two days after the broadcast. Livestream codes are usually especially short-lived, so it is worth checking official ZZZ channels during each programme.

What do Zenless Zone Zero codes give you?

Most codes grant Polychrome for Signal Searches, Denny, Investigator Logs, W-Engine materials or Bangboo upgrade items. They are a small boost rather than a replacement for event rewards, but claiming them takes only a minute.
