I still remember the first time I punched in a Zenless Zone Zero code and watched my Polychrome count jump; it felt like finding a hidden elevator in a skyscraper you thought you knew by heart. Since 2025, I’ve been treating these codes like a personal scavenger hunt, and the thrill hasn’t dimmed one bit. In case you’re new to New Eridu or have simply been missing out, let me walk you through the treasure map I’ve assembled. And yes, I’ve just tested the latest code—LUCIA1015—so you know you’re getting the real deal in 2026.

Redeeming these codes is a bit like tuning an old radio to catch a fleeting station: you need the right frequency, a steady hand, and a pinch of patience. But once you get that sweet signal, the rewards pour in. Let me show you exactly how I do it, step by tiny step. Grab your device, fire up Zenless Zone Zero, and let’s go.

🔧 My Foolproof Redemption Routine

Before anything, make sure you’re in the game and have passed the tutorial. You don’t need to be a veteran Agent, but you do need to reach level 5 for some codes (the game tells you if that’s required). Here’s the exact path I follow every time:

  1. Open the Main Menu – Tap the icon in the top-left corner of the screen. Right now, my home screen is a cozy café in New Eridu, but yours might be a dynamic combat scene. Either way, the menu button is your gateway.

  1. Locate the "More" button – Inside the menu, you’ll see a row of icons. Scroll until you spot More (it usually sits at the bottom right). This is the door to the hidden compartments, and it often gets overlooked by new players.

  1. Choose Redemption Code – Tap the More button and a fresh set of options will appear. Pick the Redemption Code feature. It looks like a gift tag, which suits its purpose beautifully.

  1. Enter the code exactly – I always copy a code from my note and paste it directly. One wrong uppercase letter and the whole thing fizzles, much like messing up a magic incantation. So I keep my code list squeaky clean.

  2. Hit Redeem – Once you tap that button, the goodies whoosh into your in-game mail. It’s that simple. I’ve made it a habit to claim everything from my mail right away, because expired rewards vanish like dew under the morning sun.

💎 Codes That Are Still Glowing in 2026

After digging through miHoYo’s official channels and testing them myself, I’ve curated a list of active codes as of early 2026. Some are seasonal, some celebrate milestones, and all of them are pure gold. I’ve marked the rewards so you know exactly what you’re snagging.

I’m simplifying the table a bit so my eyes don’t glaze over, but trust me, there are even more sparkling codes out there. The full list I keep on my phone includes quieter helpers like ZZZ20NEWSEASON and ASTRANOMICAL—the latter being my personal talisman when I first started. If a code demands level 5, I make sure to meet that before typing a single letter.

🪄 My Personal Code-Hunting Ritual

Beyond copying from a list, I treat every new code like the first firefly of a summer evening: blink and you might miss it. That’s why I’ve set up a small ritual. Every week, I peek at the official @ZZZ_EN X account, drop into the Zenless Zone Zero Discord server, and sometimes even check the Facebook page. These announcements are fleeting; they appear like ghost signals and then fade. But once you learn to listen, the freebies flow.

I also keep a note on my desktop with all active codes, refreshing it whenever a new one drops. Copy-paste is my best friend here—no typos, no frustration. If a code suddenly declares itself expired, I cross it out immediately and move on.

Now, let’s talk about the metaphors I promised. Redeeming a code isn’t just a transaction; it’s like planting a seed in New Eridu’s cracked pavement and watching a rare bloom sprout overnight. And your in-game mail? That’s a gift-laden mailbox perched at the edge of the Hollow, waiting for you to unlock its surprises after a grueling battle. Even the “Redeem” button feels like winding a music box that finally plays its melody.

🌟 More Ways to Fill Your Inventory

Codes are glorious, but they aren’t the only source of freebies. I’ve learned to weave these habits into my daily loop:

  • Daily login rewards – Just showing up in New Eridu grants items, sometimes even Polychromes. I treat it like watering a digital plant.

  • In-game mail – miHoYo occasionally sends out celebratory gifts after updates or milestones. I check my mail at least twice a day.

  • Events – Seasonal events often come with exclusive codes or straight-up rewards. The recent anniversary event dumped a mountain of goodies into my lap.

All of this together means you’re never truly dry on resources. It’s a cozy little ecosystem, and I’ve grown fond of the rhythm.

📝 Final Scribbles from My Notebook

Remember that codes are time-sensitive. What works today might gather dust tomorrow, so don’t hoard them; redeem, enjoy, and watch your Agent roster grow stronger. I’ve seen friends stockpile 30 codes and then mourn when half expired overnight. Treat each code like a delicious pastry—eat it while it’s hot.

If you discover one of the codes in my list has perished, give me a nudge in the comments. I’ll update my notepad faster than a Bangboo scurrying away from an Ethereal.

Until the next code drops, may your pulls be lucky and your Polychrome stash never run dry. Happy hunting in New Eridu!
