OS AddressBase Islands

OS AddressBase Premium Islands includes full address life cycle information, including current addresses, provisional addresses (proposed planning developments), and historic information (demolished properties) where available.
Data Enrichment with UPRN
OS AddressBase Islands can be used in any application which requires the precise location of an address in Northern Ireland, Channel Islands or Isle of Man. It can also be used to enrich records in your data with the Unique Property Reference Number (UPRN). UPRNs allows different databases to be connected based on a unique frame of reference – location.
Adding the UPRN to databases can help make deeper sense of data once it’s all linked together. Every property in Northern Ireland, Channel Islands and Isle of Man has a UPRN, and OS AddressBase Islands adds a precise location. This accurate and consistent reference system links people across multiple services, enabling data analytics and unlocking predictive insights that can underpin policy making.
