Looking for the latest working Zenless Zone Zero codes? This guide tracks active ZZZ redemption codes for free Polychrome, Denny, Investigator Logs, W-Engine materials, and other useful account resources.
Four global redemption codes remain the safest currently confirmed options: ZZZMEIJI, ZZZ31REMIELLE, ZZZ2YEAR, and ZENLESSGIFT. Players who have not previously redeemed any of them can receive up to 160 Polychrome, plus Denny and upgrade materials. CBW0884678 is also still listed as working, but it is restricted to the Asia server.
Zenless Zone Zero Version 3.1 “The Long Goodbye” is still live as September begins, with Version 3.2 “Their Secret Histories” scheduled to launch on September 9. The Version 3.2 Special Program introduced the limited code FLINTWORKS, but its redemption window ended on August 30 at 23:59 (UTC+8), so it should not be counted as an active September code. Redemption codes can expire or reach a maximum claim limit without much warning, so redeem the current codes early and collect delivered rewards from the in-game Mailbox before the mail expires.
Active Zenless Zone Zero Codes (September 2026)
| ZZZ Code | Rewards | Availability |
|---|---|---|
ZZZMEIJI NEWEST ACTIVE |
Senior Investigator Log ×3 W-Engine Energy Module ×3 Denny ×30,000 |
Global; released July 25–26, 2026; still listed as active; no public expiration date confirmed |
ZZZ31REMIELLE |
Polychrome ×60 Denny ×6,666 |
Global; released during the Version 3.1 anniversary campaign; still listed as active |
ZZZ2YEAR |
Polychrome ×50 | Global; second-anniversary code; still listed as active |
ZENLESSGIFT |
Polychrome ×50 Official Investigator Log ×2 W-Engine Power Supply ×3 Bangboo Algorithm Module ×1 |
Long-running global code; can normally be redeemed once per eligible account |
CBW0884678 |
Denny ×20,000 | Asia server only; still listed as active in current code records |
Current global reward total: up to 160 Polychrome, 36,666 Denny, three Senior Investigator Logs, two Official Investigator Logs, three W-Engine Energy Modules, three W-Engine Power Supplies, and one Bangboo Algorithm Module. Asia-server players can also try CBW0884678 for an additional 20,000 Denny.
Best redemption order: Start with ZZZMEIJI, ZZZ31REMIELLE, and ZZZ2YEAR because they are newer promotional codes with no long-term expiration guarantee. ZENLESSGIFT has remained available much longer, although players should still redeem it if they have never claimed it.
The total assumes that your account has not already redeemed ZENLESSGIFT or any of the other listed codes. A code without a published expiration date can still be disabled or reach a redemption limit at any time.
Codes No Longer Confirmed as Active
The following codes appeared in older Version 3.0 and July 2026 lists but are no longer included in the strict current global-code list used for this September update. Some trackers still display one or more of them, so they may be worth testing, but they should not be counted toward the confirmed active reward total.
| Code | Previous Rewards | Current Status |
|---|---|---|
ZZZ30BANGBOO |
Polychrome ×60, Denny ×6,666 | No longer included in the strict current-code lists checked at the end of August |
ZZZSEASON3 |
Polychrome ×50 | No longer included in the latest strict current-code list |
ROSCAELIFER0617 |
Polychrome ×30 | No longer included in the latest strict current-code list |
Important regional-code note: ZZZSUSHIRO should remain expired even though a few code pages still list it as working. The original collaboration announcement stated that redemption ended on July 28, 2026 at 23:59:59 JST, or earlier if the available code supply ran out. This guide gives priority to that published deadline.
You can safely test an uncertain code through the official HoYoverse redemption page. If the system accepts it, claim the delivered reward immediately. If it returns an expired or invalid message, do not rely on an older tracker that still lists it.
Recently Expired ZZZ Codes
The most important change for the September update is FLINTWORKS. It was released during the Version 3.2 Special Program on August 28 and offered 300 Polychrome, but its short redemption window ended before September began.
| Expired Code | Previous Rewards | Reason |
|---|---|---|
FLINTWORKS |
Polychrome ×300 Denny ×30,000 Senior Investigator Log ×2 W-Engine Energy Module ×3 |
Version 3.2 Special Program code; expired August 30, 2026 at 23:59 UTC+8 |
REMIELLE0729 |
Polychrome ×120 | Official 2nd Anniversary livestream code; expired July 29, 2026 at 24:59:59 JST |
ZZZSTEAM |
Polychrome ×60 Senior Investigator Log ×2 W-Engine Energy Module ×2 Denny ×6,666 |
Official Steam wishlist milestone code; expired July 29, 2026 at 04:00 UTC+8 |
ZZZSUSHIRO |
Senior Investigator Log ×3 Denny ×30,000 |
Asia-server collaboration code; expired July 28, 2026 at 23:59:59 JST or earlier if the available redemption supply was exhausted |
ZZZY2ANNIV |
Polychrome ×300 Senior Investigator Log ×2 W-Engine Energy Module ×3 Denny ×30,000 |
Version 3.1 Special Program code; expired July 19, 2026 at 23:59:59 UTC+8 |
ZZZDREAMLAND |
Polychrome ×30 Denny ×6,666 |
Maximum number of redemptions reached |
FLINTWORKS should not appear in an active September-code table. HoYoverse announced that the Version 3.2 Special Program would include an exclusive redemption code, and post-stream code records identify FLINTWORKS as that reward. Its claim period ended on August 30 at 23:59 UTC+8.
The Version 3.1 Special Program code ZZZY2ANNIV also provided 300 Polychrome but had a similarly short claim period. REMIELLE0729, ZZZSTEAM, and ZZZSUSHIRO remain expired, while VRELEASE31 also remains unavailable after reaching its maximum redemption limit.
What Are Zenless Zone Zero Codes?
Zenless Zone Zero redemption codes are promotional codes distributed by HoYoverse around Special Programs, version previews, anniversaries, platform launches, collaborations, web events, community campaigns, and other promotions.
Rewards vary between campaigns. A code may provide:
- Polychrome
- Denny
- Senior or Official Investigator Logs
- W-Engine Energy Modules
- W-Engine Power Supplies
- Bangboo upgrade materials
- Ether Batteries
- Other progression materials
There is no guaranteed number of new codes each month. Several codes can appear around an anniversary or major version update, followed by weeks with no new public redemption code.
Special Program codes normally offer some of the largest Polychrome rewards but also have the shortest deadlines. FLINTWORKS is the latest example: it offered 300 Polychrome but expired before September began.
How to Redeem Zenless Zone Zero Codes
Zenless Zone Zero supports both in-game and browser-based code redemption. Most codes require your account to have reached at least Inter-Knot Level 5. You also need to have created a game character and linked the correct HoYoverse Account before using the website.
Method 1: Redeem Codes In-Game
- Launch Zenless Zone Zero and sign in to the account that should receive the rewards.
- Make sure your account has reached at least Inter-Knot Level 5.
- Open the main menu from the upper-left corner.
- Select More near the bottom of the menu.
- Select Redemption Code.
- Copy and paste the active code into the field.
- Select Redeem or Confirm.
- Open the in-game Mailbox.
- Open the reward mail and collect its attachments.
Mailbox deadline: HoYoverse's redemption guidance states that rewards delivered through in-game mail are generally available to claim for 30 days. Do not redeem a code and then leave the reward sitting unclaimed indefinitely.
Method 2: Use the Official Redemption Website
- Open the official Zenless Zone Zero redemption page.
- Sign in with the HoYoverse Account linked to your Zenless Zone Zero character.
- Select the correct server: America, Europe, Asia, or TW/HK/MO.
- Confirm that the correct character appears.
- Enter the redemption code.
- Select Redeem.
- Launch Zenless Zone Zero.
- Open the Mailbox and collect the delivered rewards.
If the website cannot find a character, make sure you have already created a Zenless Zone Zero character on that HoYoverse Account and selected the correct server.
Do not use browser extensions, APK files, scripts, or external programs that promise to redeem codes automatically. Use the game's built-in redemption menu or the official HoYoverse website.
Why Is My ZZZ Code Not Working?
- The Code Has Expired: Special Program, livestream, collaboration, and regional codes can have extremely short deadlines. FLINTWORKS expired on August 30, while REMIELLE0729 expired on July 29 and ZZZY2ANNIV expired on July 19.
- The Maximum Redemption Limit Was Reached: Some codes are disabled after enough players claim them. ZZZDREAMLAND and VRELEASE31 reached their available usage limits.
- Your Inter-Knot Level Is Too Low: HoYoverse's redemption guidance states that some codes may not be redeemable until you reach Inter-Knot Level 5.
- The Code Was Entered Incorrectly: Copy the code directly and remove quotation marks, spaces, or line breaks before and after it.
- The Code Was Already Used: A public code can normally only be redeemed once on the same eligible HoYoverse game account.
- The Code Does Not Support Your Server: Some promotions are region-specific. ZZZSUSHIRO and CBW0884678, for example, were associated with the Asia server.
- The Wrong Server Was Selected Online: Choose the server where your intended game character was created.
- The Reward Has Not Appeared: Check the in-game Mailbox. Restart the game if the message does not appear immediately.
- The Reward Mail Expired: Redemption mail does not remain available forever. Collect attachments before the message expires.
- A Tracker Is Outdated: Some code pages continue to display expired codes after their official redemption periods have ended.
- There Is a Temporary Server Issue: Try the official redemption service again later. If an accepted code never delivers its reward, contact HoYoverse Customer Service and provide your UID, server, code, and relevant screenshots.

When Are New ZZZ Codes Released?
Zenless Zone Zero codes do not follow a guaranteed schedule. HoYoverse most commonly distributes them during:
- Version Special Programs and preview livestreams
- Anniversary celebrations
- New platform launches
- Character and version promotional campaigns
- Collaborations and regional events
- Community milestones
- Official social-media campaigns
- Special livestreams and anniversary broadcasts
Special Program codes usually expire very quickly. FLINTWORKS, released during the Version 3.2 Special Program, lasted only through August 30. Standard campaign codes can remain active for several weeks, but codes with no announced deadline can still reach their maximum redemption supply without advance notice.
Where to Find New Zenless Zone Zero Codes
Official Zenless Zone Zero website: Check current update notices, events, platform launches, anniversary campaigns, and version announcements.
Official X and social media: HoYoverse can release smaller promotional codes through social-media campaigns, collaborations, and character-related posts.
HoYoLAB: Official announcements, Special Program posts, anniversary information, and campaign notices frequently appear on HoYoLAB.
Special Programs: Version-preview broadcasts commonly release a high-value code worth around 300 Polychrome, but these livestream codes often expire within roughly a day.
Anniversary broadcasts: Special livestreams can also provide short-duration codes. REMIELLE0729, for example, appeared during the Version 3.1 2nd Anniversary broadcast.
Collaborations: Regional and real-world collaborations may provide limited codes that only work on selected servers or while redemption supplies last.
This article: Check the Last checked date before using the list. Newly confirmed codes are placed in the active table, while expired, quota-limited, and insufficiently confirmed codes are separated from the current reward total.
How to Get More Free Polychrome
Redemption codes are not the only source of free Polychrome. Daily Errands, story commissions, achievements, limited events, Shiyu Defense, Hollow Zero, character trials, maintenance compensation, anniversary rewards, HoYoLAB campaigns, and other activities can all provide additional resources.
Version 3.1 continues through the start of September with its 2nd Anniversary reward cycle. The official anniversary overview includes 1,600 Polychrome, a limited S-Rank Agent selection reward with a corresponding W-Engine selection, 20 Encrypted Master Tapes, and 10 Boopons through the version's login and event activities.
Prioritize limited-time events before permanent story and exploration content. Permanent commissions can be completed later, while event rewards disappear when their claim periods end.
Version transition: Version 3.2 “Their Secret Histories” officially launches on September 9, 2026, bringing Claret, Roxy, new outfits, returning Agent Signal Searches, new story content, and new events. Check the official update notice around maintenance for any additional compensation or launch rewards.
Zenless Zone Zero Top-Up Options
The redemption codes in this article are free. Players who need additional Monochrome or an Inter-Knot Membership can check the current products on the BuffHub Zenless Zone Zero top-up page.
Version 3.1 reset the Monochrome Market first-purchase double bonus for all Monochrome tiers. After the reset, the first purchase of each eligible tier can receive the refreshed double reward.
If you had an unused first-purchase bonus on a tier before the Version 3.1 reset, that old unused bonus does not stack with the new one. In other words, the same tier cannot trigger two first-purchase double bonuses after the reset.
Prices, bonuses, product availability, currencies, and delivery requirements can change. Before purchasing, confirm the UID, server, product name, included Monochrome, applicable bonus, delivery method, and final checkout price.
Prefer official HoYoverse or supported platform payment channels. Never give another person your HoYoverse password, email verification code, two-factor authentication code, recovery information, or social-login credentials.

No. The Version 3.1 Special Program code expired on July 19, 2026 at 23:59:59 UTC+8.
What does ZZZ2YEAR provide?

Yes. CBW0884678 remains listed as active and provides 20,000 Denny, but it is restricted to the Asia server. It is not included in the global 160-Polychrome total.
Where do I enter Zenless Zone Zero codes?
Reach at least Inter-Knot Level 5, then open Menu > More > Redemption Code. You can also use the official HoYoverse Zenless Zone Zero redemption website.
How long do ZZZ reward mails last?
HoYoverse's redemption guidance states that rewards delivered through in-game mail are generally available to claim for 30 days. Open the Mailbox and collect the attachments rather than leaving the reward unclaimed.
Can I redeem one code on multiple accounts?
Each separate eligible HoYoverse account can normally redeem the same public code once, provided the code has not expired, reached its maximum redemption supply, or been restricted to a specific server.
Do ZZZ codes work across PC, mobile, PlayStation, and Xbox?
Redemption is tied to the HoYoverse game account and character rather than one individual device. Account-linking, server, and campaign restrictions can still apply.
Are Zenless Zone Zero codes case-sensitive?
Current redemption guidance indicates that capitalization does not normally prevent the listed codes from working. Even so, copying every code exactly as published remains the safest method because it avoids missing characters, accidental spaces, or confusion between similar-looking symbols.
Did Version 3.1 reset the first-purchase bonus?
Yes. HoYoverse officially reset the Monochrome Market first-purchase double bonus for all Monochrome tiers after the Version 3.1 update. Unused pre-reset bonuses do not stack with the refreshed bonus.
How often are new ZZZ codes released?
There is no fixed monthly schedule. New codes appear irregularly during Special Programs, anniversaries, collaborations, platform launches, version campaigns, livestreams, and other official promotions.
When was this Zenless Zone Zero code guide updated?
This page was last source-checked on August 31, 2026 for the September update. FLINTWORKS was moved to the expired section after its August 30 deadline, while ZZZMEIJI, ZZZ31REMIELLE, ZZZ2YEAR, and ZENLESSGIFT remain the four best-supported global codes. CBW0884678 remains available for the Asia server.
Conclusion
As of August 31, 2026, Zenless Zone Zero has four consistently confirmed global redemption codes worth up to 160 Polychrome, along with Denny and useful upgrade materials: ZZZMEIJI, ZZZ31REMIELLE, ZZZ2YEAR, and ZENLESSGIFT. Asia-server players can also try CBW0884678 for 20,000 Denny.
The main change for the September update is FLINTWORKS. The Version 3.2 Special Program code provided 300 Polychrome but expired on August 30 at 23:59 UTC+8, so it should not appear in the active table. REMIELLE0729, ZZZSTEAM, ZZZSUSHIRO, and ZZZY2ANNIV also remain expired.
Redeem the four current global codes as soon as possible, use only the in-game redemption menu or official HoYoverse website, and remember to collect every reward from the Mailbox before its message expires.
