Denmark’s Address Register (DAR)

Denmark’s Address Register (DAR) is the authoritative Basic Data Register for addresses and road names. The aim is to provide fair addresses and road names to authorities, businesses and citizens. Public registers such as CPR, CVR and BBR are obliged to use only authoritative addresses from DAR. Addresses and road names are determined by the municipal address authorities in the DAR. Approximately 3.9 million addresses have been registered in DAR and around 111,000 road names. Address data is continuously updated, with approximately 230,000 changes in address data per year. Road names data, including the geometry of the road name, are continuously updated, with approximately 16,000 changes mainly in the geometry of the road name. An address is a composite term which designates and denotes a specific access road to an unbuilt area, a building, part of a building, a technical plant or the like. The compound name of an address consists of the road name, the house number, any floor name and door name, any additional town name and the postcode with the name of the postcode area in which the address is located. The address names of all addresses are unique at national level. Road names are represented by a geometry and are described as a total traffic area, regardless of the boundaries of the municipality for which a single road name has been determined. Road names are unique within a radius of 15 km and within a postal code. This ensures that identical or identical road names are not confused.丹麦地址注册簿（Denmark’s Address Register，DAR）是地址与道路名称领域的权威基础数据登记册。其设立目标是为官方机构、企业及公民提供合规的地址与道路名称服务。CPR、CVR、BBR等公共登记系统仅可使用源自DAR的权威地址，地址与道路名称的审定工作由各市政地址管理机构在DAR框架内完成。 目前DAR已登记约390万个地址与11.1万个道路名称。地址数据持续更新，每年约产生23万条变更记录。道路名称数据（含道路几何形状信息）同样处于持续更新状态，每年约产生1.6万条变更，其中多数为道路几何形状相关调整。 地址属于复合术语，用于指定并标识通往未开发区域、建筑物、建筑物局部、技术设施等的特定通行道路。地址的完整复合名称由道路名称、门牌号、可选楼层名称、可选户室名称、附加城镇名称，以及标注地址所在邮编区域名称的邮编组成。全国范围内所有地址的名称均具有唯一性。 道路名称以几何形状进行表征，并被界定为完整的交通通行区域，不受该道路名称所属的市政管辖边界限制。道路名称在15公里半径范围及邮编区域内均具有唯一性，以此避免同名或完全相同的道路产生混淆。
