Let's cut straight to the chase – who doesn't love free stuff in their favorite gacha game? If you're grinding through New Eridu and need some extra Polychrome for those crucial pulls, you've landed in the right place.
Active Zenless Zone Zero Redeem Codes - October 2025
Here's what's actually working right now (and trust me, I've tested these myself):
ZZZ23SWEETILY is your bread and butter – 60 Polychrome plus 6,666 Dennies, and the best part? No expiration date. That's rare in the gacha world, so definitely grab this one.
ZENLESSGIFT serves as the permanent starter code everyone should know about. You'll snag 50 Polychrome, 2 Official Investigator Logs, 3 W-Engine Power Supplies, and 1 Bangboo Algorithm Module. Not bad for typing a few letters, right?
Now, KRAMPUS – this one stings a bit. It expired November 16, 2025, at 11:59 UTC+8. If you missed it, you lost out on 300 Polychrome, 2 Senior Investigator Logs, 3 W-Engine Energy Modules, and 30,000 Dennies. (I'm still kicking myself for almost missing this one during the livestream.)

Code Rewards Breakdown
Let me break down what you're actually getting here:
ZZZ23SWEETILY: 60 Polychrome + 6,666 Dennies
ZENLESSGIFT: 50 Polychrome + upgrade materials bundle
Expired KRAMPUS: 300 Polychrome + premium materials
Quick math check – 60 Polychrome equals one-third of a gacha pull, while 300 Polychrome provides nearly two full pulls since 160 Polychrome equals 1 Encrypted Master Tape. Every bit counts when you're chasing that S-rank agent.
How to Redeem Zenless Zone Zero Codes
Official Website Method
This is honestly the easiest route. Head to zenless.hoyoverse.com/redemption – no Inter-Knot Level 5 requirement here, which is clutch for newer players:
Log in with your HoYoverse account
Select the correct server region (don't mess this up!)
Enter the code exactly as shown – these things are case-sensitive
Click Redeem and check your in-game mailbox
In-Game Redemption Process
You'll need Inter-Knot Level 5 for this method, which unlocks after completing the Business x Strangeness x Justness chapter:
Open main menu > More tab > Redemption Code
Enter code and tap Redeem
Access rewards through More > Mail
Pro tip from my experience: if you're below Level 5, just use the website method. Way less hassle.
October 2025 Reward Types and Values
Polychrome Distribution
Here's where the rubber meets the road. 160 Polychrome = 1 Encrypted Master Tape, so let's see what these codes actually give you:
Standard codes: 50-60 Polychrome
Livestream codes: 300 Polychrome
You'll need 3-4 standard codes for one guaranteed pull
The math isn't exactly generous, but hey – free is free.
Upgrade Materials Catalog
These materials might not seem exciting, but they're absolute lifesavers when you're trying to max out your favorite agents:
Official/Senior Investigator Logs: Agent XP materials (the good stuff)
W-Engine Power Supplies/Energy Modules: Weapon upgrade components
Bangboo Algorithm Modules: Companion upgrade resources
Senior Investigator Logs are honestly the most valuable here – high-level agent advancement gets expensive fast.

Dennies and Currency Rewards
Let's talk about the often-overlooked Dennies:
Standard codes: 6,000-6,666 Dennies
Premium codes: 30,000+ Dennies
Agent Level 60 promotion requires 800,000 total Dennies
That last number should make you appreciate every Dennie you can get from codes. Trust me on this one.
Code Redemption Troubleshooting
Common Error Messages
Code has expired: This usually hits with livestream codes that expire within 24-48 hours. Permanent codes like ZENLESSGIFT stick around indefinitely, thankfully.
Code already used: Each code works once per account only. No double-dipping here.
Invalid code format: These codes are case-sensitive, and I've seen people confuse 0 with O more times than I can count.
Account Requirements
Inter-Knot Level 5 unlocks after about 2-3 hours of gameplay. If you're below Level 5, the website method is your friend – rewards will appear once you hit the requirement.

Maximizing Free Resources in ZZZ
Daily Collection Methods
Don't sleep on these daily income sources:
Daily Errands: 60+ Polychrome daily (consistent and reliable)
Commissions: Variable amounts from story/sub-quests
Scratch Cards: 0-40 Polychrome daily via RNG (your mileage may vary)
One-Time Reward Sources
Road to Proxy Greatness: 1,600 Polychrome for hitting Inter-Knot Level 30. That's equivalent to 10 gacha pulls – absolutely worth the grind.
Primer Rewards: 1,050 Polychrome through trial completions.
Agent Demos: 20+ Polychrome each via 5-minute gacha trials. Quick and easy money.
Code Redemption Tips and Best Practices
Here's my hard-earned advice: redeem codes immediately upon discovery. Those expiration timers are ruthless.
Set notifications for official ZZZ social media and monitor community Discord servers for real-time alerts. I've missed too many good codes by checking a day too late.
Prioritize Polychrome for limited banner Encrypted Master Tapes over permanent gacha – the limited agents are usually worth the investment. Use code Dennies for agent promotion rather than daily purchases where possible. And always claim mailbox rewards promptly to prevent that 30-day expiration from sneaking up on you.
