中国正式推出房屋建筑统一代码制度，为每栋房子赋予唯一身份标识[1]。住房城乡建设部和国家数据局在2026年6月11日发布《关于全面建立房屋建筑统一代码制度的通知》[1]，规定至2027年底，全国新建房屋都将配备该统一代码，并完成赋码和落图的全覆盖[1]。
该制度的核心目标是通过"一码串联"实现水电气等相关部门的信息共享，大幅简化办理流程[1]。杭州已率先开展试点，购房人在"e房通"平台完成合同网签后，可以通过该统一代码实现水电气开户的一键授权[1]。到2030年底，将完成全国所有房屋的代码覆盖，并建成房屋建筑全生命周期的高质量数据集[1]。
China has launched a unified building identification code system designed to assign each residential structure a unique digital identity.[1] The initiative was formally announced on June 11, 2026, by the Ministry of Housing and Urban-Rural Development and the National Data Administration through an official notice establishing the comprehensive framework.[1]
The rollout follows a phased implementation schedule. By the end of 2027, all newly constructed buildings across the nation are required to be assigned and registered with the unified code system.[1] The codes enable seamless information sharing across utilities and government departments through a mechanism termed "one-code linkage," substantially reducing administrative procedures for residents.[1] Hangzhou has already piloted this functionality, allowing homebuyers to complete contract registration through the "e-Fang-Tong" platform and then use the code to authorize water, electricity, and gas connections with a single click.[1]
By the end of 2030, the system aims to achieve complete coverage of all buildings nationwide and establish a comprehensive, high-quality dataset documenting each structure's full lifecycle.[1]
