ZZZ Redeem Codes — FAQ

How many ZZZ codes are working right now?

As of Aug 22, 2026, there are 8 working Zenless Zone Zero redeem codes: ZZZ31REMIELLE, ZZZMEIJI, ZZZ2YEAR, ZENLESSGIFT, ZZZ30BANGBOO, ZZZSEASON3, ROSCAELIFER0617, ZZZSTEAM. Every code on this list was manually tested in-game on that date and confirmed to redeem successfully. Together they are worth 360 Polychrome plus Denny and upgrade materials.

How do I redeem codes in Zenless Zone Zero?

Two ways. In-game: open the Main Menu, tap More (the … button), choose Redemption Code, paste the code and confirm — you must be Inter-Knot Level 10 or higher. On the web: go to zenless.hoyoverse.com/redemption, log in with the HoYoverse account linked to your save, pick your server and character, then enter the code. Either way the rewards land in your in-game mailbox.

What do ZZZ codes give you?

Mostly Polychrome — the premium currency used for Signal Search pulls — plus Denny, Investigator Logs for agent EXP, W-Engine Power Supplies and Energy Modules for weapon EXP, and Bangboo Algorithm Modules. This page lists the exact contents and quantity of every code.

Why is my ZZZ code not working?

Four common reasons: the code expired (most are tied to a livestream or patch and last only a few days), you are below Inter-Knot Level 10, the code is region-locked to a specific server, or you already redeemed it — each code works once per account. Codes are also case-sensitive, so copy them rather than typing them by hand.

Do ZZZ redeem codes expire?

Yes. Livestream codes are the shortest-lived, usually lasting only 24 to 48 hours after the broadcast, which is why they should be redeemed immediately. Version and collaboration codes typically run for the length of a patch, and a small number of starter codes such as ZENLESSGIFT have no announced end date.

How often are new ZZZ codes released?

New codes drop with every version preview livestream — roughly every six weeks, at the start of each patch — plus anniversaries, collaborations and milestone celebrations. This page is re-tested and updated as new codes are announced.

Can I use the same ZZZ code twice?

No. Each code can be redeemed once per account, and entering an already-used code returns an error instead of a duplicate reward. Some codes with identical rewards are alternates of each other: redeeming one marks the others as used.
