Promo codes in Zenless Zone Zero are one of the fastest ways to stock up on Polychrome, Denny, and valuable upgrade materials without spending a single cent. HoYoverse drops these codes through live streams, social media events, and seasonal milestones, but they expire quickly. Miss the window and the rewards are gone for good. This guide keeps you ahead of the curve with every active code, a clear breakdown of what each one gives you, and a simple walkthrough for redeeming them inside the game or through the official website.
What Active Codes Are Available Right Now?
The codes listed below are currently active and ready to claim. Enter them exactly as shown, since codes are case-sensitive.
warning
These codes are time-limited and will expire without notice. Redeem them as soon as possible to avoid losing the rewards permanently.
Among the current batch, ZZZGIGO stands out as the newest addition, offering a W-Engine Energy Module alongside a generous 15,000 Denny. If you only have time to redeem one code today, start with that one.

How Do You Redeem Codes in Zenless Zone Zero?
There are two methods available, and both work equally well. Pick whichever fits your current situation.
Method 1: Redeem Through the Official Website
This is the quickest option if you are browsing on a desktop or do not want to open the game.
- Visit the official Zenless Zone Zero redemption page at zenless.hoyoverse.com/redemption
- Log in with your HoYoverse account
- Select the correct server and character
- Type or paste your code into the input field
- Hit the confirm button to process the reward
Your items will appear in your in-game mailbox within a few minutes.
Method 2: Redeem Directly Inside the Game
- Open the pause menu using the icon in the upper-left corner of the screen
- Select More from the menu options
- Tap Redeem Code
- Enter your code and press Redeem to confirm
danger
The in-game code redemption feature only unlocks after you complete the prologue. If the option is greyed out, finish the opening story sequence first.
Once redeemed, rewards land in your mailbox automatically. You have 90 days to collect them before they expire, so there is no rush after claiming, but do not forget entirely.
What Rewards Can Codes Give You?
Understanding what each reward type does helps you prioritize which codes matter most for your current progression stage.
info
If you are saving for a specific banner, stack every Polychrome code you can find. At 160 Polychrome per pull, even a 50-unit code gets you nearly a third of the way to one Signal Search.
Why Do Codes Expire So Quickly?
HoYoverse uses expiring codes as a way to reward engaged players and drive activity around specific events, patch launches, and live streams. Codes tied to major patch announcements (like the SOLDIER0ANBY code that gave 300 Polychrome at launch) are typically the most generous but also the shortest-lived. Codes distributed during official broadcasts often expire within 24 to 48 hours of the stream ending.
Seasonal and milestone codes like ZZZ26DELUSION and ZZZ25ROWBY tend to stay active longer, sometimes for several weeks into a patch cycle. Checking back regularly is the best way to catch new drops before they disappear.
info
Codes cannot be redeemed more than once per account. If you enter a code and receive a "already claimed" message, that simply means you redeemed it during a previous session.
What Happened to the Old Codes?
Expired codes are permanently inactive and cannot be used regardless of when you started playing. Notable past codes include VIRTUALREVENGE and ZZZFREE100, both of which gave 300 Polychrome each, making them among the most valuable codes ever distributed. The launch code ZENLESSLAUNCH offered 60 Polychrome and 6,666 Denny to everyone who redeemed it during the game's opening period.
These expired codes are documented here for reference, but entering them today will return an error. Focus your energy on the active list above.
