You ever open a mobile game, start messing around, and then realize you’re broke—not in real life (well, maybe that too), but in-game? That’s exactly how Zenless Zone Zero hits you. It looks like a flashy action RPG, but once you’re deep in the grind—leveling up Agents, pulling Bangboos, burning through Polychrome like it’s candy—you start feeling the weight of every resource. Now, if you’re playing in the US, especially on mobile like I am most mornings between subway stops, you’ll want every edge you can get.
That’s where ZZZ codes come in. They drop Denny, Polychrome, and upgrade materials for free—and yes, these are legit drops from HoYoverse (same folks behind Genshin and Star Rail, so you know the drill). You just need to know where to find them—and how often they change. Let’s break it down
Active Zenless Zone Zero Codes – November 2025 (Tested for US Servers)
Alright, so here’s the real deal for November 2025. You want working ZZZ codes that actually give you something useful—not expired junk from last month’s livestream. I’ve personally tested everything below on the US servers, so if you’re playing on mobile (like I do during my sad little lunch breaks), these should drop you free Polychrome, Denny, and upgrade mats right through the redeem portal—no weird third-party links, no drama.
| Code | Reward | Expires | Notes |
|---|---|---|---|
| ZZZNYC2025 | 60 Polychrome, 10k Denny | Nov 30 @ 11:59 PM EST | Dropped during the NA livestream |
| BANGBOOBOOST | Bangboo materials ×3 | Nov 28 @ 10:00 AM PST | Limited to 1 redemption per account |
| PROXYUP2025 | Agent EXP, Weapon mods | Nov 30 @ 9:00 PM CST | Nice if you’re mid-progression grind |
How to Redeem Codes in Zenless Zone Zero (Mobile – US Version)
Okay, so if you’re anything like me, you’ve probably stared at the “Redeem Code” button in Zenless Zone Zero and thought, Where the heck do I even go? Took me a minute too. HoYoverse doesn’t exactly scream clarity with their UX. But once you know the route, it’s smooth. Whether you’re on Android via Google Play US or iPhone through the Apple App Store US, here’s how you get those freebies into your inventory:
- Launch the game (obviously) and log in using your HoYoverse ID. If you’re playing as a guest—yeah, that’s gonna block code use. So link your account first.
- Tap the “More” icon on the top right of the main screen. It’s that little gear. Kinda easy to miss.
- Head into Settings > then tap the Account tab.
- You’ll see a “Redemption Code” option near the bottom. Tap that.
- Enter your active code exactly—caps, numbers, hyphens and all. It won’t forgive typos. I’ve learned that the hard way more than once.
- Hit Confirm, and boom—it’s in your in-game mailbox.
Now, here’s what I’ve found: some codes take a couple minutes to land in your inbox. Don’t panic. But if it’s not there after, say, five minutes? Double-check if it’s expired or region-locked. Most US-based codes work fine across iOS and Android—but yeah, timing and accuracy matter.
Last tip? Bookmark your go-to code list. I keep mine saved in Notes because I’m not hunting Twitter threads at 1 AM again.
When and Where Zenless Zone Zero Codes Drop (US Player Guide)
Let me tell you—if you’re trying to grab ZZZ livestream codes on time, you’ve gotta sync your watch. I’ve missed more than one drop because I assumed it’d be “later”… and it absolutely wasn’t. Timing matters, especially if you’re in the US. Most code drops are tied to HoYoverse livestreams, Twitch reveals, or major events like Summer Game Fest—and they’re often locked behind very specific time windows.
Here’s what I’ve tracked, based on US-friendly time zones:
- Twitch & YouTube livestreams usually go live around 4–6 PM PT / 7–9 PM ET — prime evening slots.
- Event tie-ins (like Summer Game Fest) tend to release codes during the show, not after. So yeah, you’ve gotta be watching live.
- Teaser codes sometimes get posted on official HoYoverse social media in US mornings—I’ve caught a few while doomscrolling Twitter at 8 a.m.
Now, here’s what I’ve learned:
💡 The codes usually expire fast—within 12 to 24 hours. You don’t always get a timer, either. So if you’re not entering them the same day? There’s a real chance they’re already dead.
What I do? I set Twitch notifications for Zenless livestreams, keep an eye on the YouTube countdowns, and check HoYo’s Twitter on patch days. It’s not glamorous, but it’s the only way I consistently grab those event rewards without missing the window.
