Finding fresh Zenless Zone Zero codes remains a smart way for players to stock up on polychromes, dennies, and growth materials without spending extra time on the grind. HoYoverse releases these codes in waves, usually during version update livestreams, seasonal events, anniversary celebrations, and platform-specific milestones. Some codes linger for a few weeks, while others disappear quickly, so players should redeem them as soon as possible. In 2026, the active code pool offers several useful bundles that cover signal searches, agent upgrades, and W-Engine enhancements.

🎁 What Players Can Earn

Zenless Zone Zero codes commonly grant four major types of resources. Polychromes are the premium currency used for signal searches, making them especially valuable for players who want to expand their agent roster. Dennies act as the standard currency for many upgrade tasks, while Senior Investigator Logs provide a large amount of experience for agents. W-Engine Energy Modules and Bangboo Algorithm Modules support equipment and companion progression. Some codes also include Official Investigator Logs, power supplies, and plating agents for additional tuning.

🕒 Expired Codes and Rotation Patterns

Codes are often tied to specific events, so many older entries are no longer redeemable. Trying an expired code will simply fail without granting rewards. Some notable expired codes include:
