Register of Geographic Codes (December 2023) for the UK

The Register of Geographic Codes (RGC) is a key product that contains the definitive list of UK statistical geographies. ONS maintains the definitive set of statistical geographies, coordinates the issue of new codes, and maintains the relationship between active and archived code ranges on behalf of the Government Statistical Service. The RGC should be used in conjunction with the Code History Database, available to download separately.地理代码登记册（Register of Geographic Codes, RGC）是一款核心产品，收录了英国统计地理区域的权威名录。英国国家统计局（Office for National Statistics, ONS）负责维护这套权威统计地理区域集合，协调新代码的发布工作，并代表政府统计服务处维护有效代码区间与已归档代码区间之间的关联关系。地理代码登记册（RGC）需与可单独下载的代码历史数据库（Code History Database）配合使用。
