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.Updated GeographiesUpdates to Parishes (E04) (name change), Wards (E05) (name change), NMD (E07) (name change), Clinical Commissioning Groups in England (E38), NHS (Region, Local Office) (E39) and NHS England Regions (E40)Updates to Council Areas (S13) and Wards (S13)
