Zenless Zone Zero Codes: Active & How to Redeem

Updated 6 November 2026 · Standard formula, shown below

Zenless Zone Zero redemption codes are short alphanumeric strings that grant free in-game currency, materials, and other rewards. This article covers what codes are currently active, how to redeem them on any platform, and answers common questions about them.

What Are Zenless Zone Zero Codes?

Zenless Zone Zero (ZZZ) is a free-to-play action RPG by HoYoverse. The developers periodically release promotional codes through social media, livestreams, and partner events. Each code is a one-time-use string that you enter on the official redemption website or in-game to claim rewards like Polychrome (the premium currency), Dennies (in-game money), and upgrade materials. Codes are usually time-limited and often expire within a few weeks of release.

How to Redeem Codes

There are two main ways to redeem a code, depending on your device. The official website works for all platforms, while the in-game method is only for mobile and PC.

Via the Official Redemption Website

Go to the official Zenless Zone Zero redemption page (linked from the game’s official site or social media).
Log in with your HoYoverse account (the same account you use to play the game).
Select your server (America, Europe, Asia, or TW/HK/MO).
Enter your character’s UID (found in the in-game profile).
Paste the code into the redemption box and click “Redeem.”
Check your in-game mail within 24 hours to claim the rewards.

In-Game (Mobile and PC)

Open the game and go to the menu (phone icon on mobile, Esc on PC).
Select “Settings” (gear icon).
Choose “Account” and then “Redeem Code.”
Enter the code and confirm. Rewards arrive via in-game mail.

Where to Find New Codes

New codes are typically announced on official channels. The most reliable sources are:

The official Zenless Zone Zero Twitter/X account (@ZZZ_EN)
The official Discord server
Official livestreams (version update special programs)
Partner content creators who receive exclusive codes
The official HoYoverse website news section

Codes are often tied to milestones (e.g., 1 million followers) or version anniversaries. During livestreams, codes are shown on-screen for a limited time (usually 24 hours).

Common Problems and Solutions

If a code doesn’t work, check these common issues:

Expired: Most codes expire within 1-3 weeks. If it’s older than that, it’s likely invalid.
Already used: Codes are one-time per account. You can’t reuse them.
Wrong server: Codes are region-specific. A code for the Asia server won’t work on the America server.
Case sensitivity: Codes are usually case-insensitive, but type them exactly as shown.
Spelling errors: A single wrong character makes the code invalid. Copy-paste from the official source if possible.

What Rewards Do Codes Give?

Typical rewards include:

Polychrome – the premium currency used to pull for characters and W-Engines (weapons). Codes often give 50-300 Polychrome.
Dennies – the basic in-game currency for upgrades.
Investigation Merits – used to buy materials in the in-game shop.
Level-up materials – like W-Engine Energy Modules and character EXP chips.
Battery Charge – stamina refills for farming.

Are Codes Safe to Use?

Yes, official codes are safe. However, be cautious of third-party sites that claim to generate codes or offer “free Polychrome” in exchange for your login details. These are scams. Only redeem codes from the official website or in-game menu. Never share your account password or give your account to a service that promises free rewards.

Frequently Asked Questions

How often are new codes released?

There’s no fixed schedule. Codes are usually released during major version updates (every 6 weeks), special events, or when the official social media accounts hit follower milestones. You might see a few codes per month, but sometimes there are gaps of several weeks.

Can I use codes on multiple accounts?

Yes, each code can be used once per account. If you have multiple accounts, you can redeem the same code on each one, as long as the code hasn’t expired.

Do codes work on all platforms (PC, mobile, PS5)?

Yes, codes are tied to your HoYoverse account, not the platform. As long as you log in with the same account, the rewards will appear in your in-game mail regardless of whether you’re playing on PC, mobile, or PlayStation.

Why did my code say “already used” when I never redeemed it?

This can happen if you accidentally redeemed it on a different server or a different HoYoverse account. Double-check the server selection on the redemption page and make sure you’re logged into the correct account. If you’re sure you haven’t used it, contact HoYoverse support.

Can I redeem codes after they expire?

No. Once a code expires, it cannot be redeemed. There’s no way to extend the validity. Always redeem codes as soon as you get them.

Where can I find the UID?

Your UID is a 9-digit number found in your in-game profile (click on your avatar in the top-left corner of the main menu). It’s also shown on the loading screen. You’ll need it for website redemption.
