You may be a large business, looking for APIs to integrate with your own GIS. Perhaps you’re an independent developer who wants to create a new web or mobile app. Either way, you’re welcome to trial all three features of the OS Places API free of charge. All we ask is that you don’t go over 10,000 transactions (combined, across all three features).
With this API, you’ll enable users to identify addresses accurately, quickly, and with reliable high levels of detail. OS Places API has the benefit of accessing historic data in the property’s lifecycle too, which should reduce ambiguity throughout. It opens up three essential, time and money-saving pieces of functionality:
-
Geosearch – enabling finds of addresses or reverse geocoding via radius search, or by drawing a boundary box.
-
Matching & Cleansing – integrating with existing systems to enable faster, more accurate postcode look-ups and autocompletion on websites and Enterprise customer service systems.
-
Capture & Verification – checking address data, quickly and reliably, to enable deduping of entries in already populated databases and provide verified uniformity.
OS Places API derives data from our AddressBase Premium dataset – Great Britain’s most detailed view of addresses and their life cycles, including everything from planning to creation to change of use and demolition.
AddressBase itself contains local authority, Ordnance Survey and Royal Mail addresses, current and alternative addresses, provisional addresses (still in the planning stage) and historic information too, where it’s available. It also includes Objects Without Postal Addresses (OWPAs) and cross references to the OS MasterMap TOIDs, as well as:
-
Up to date cross references to our large-scale data, such as OS MasterMap Topography Layer and Integrated Transport Network Layer via the TOID – but also references to objects that don’t have postal addresses, as well as coordinates that have been verified via our surveyors.
-
Data from the Local Land and Property Gazetteer and One Scotland Gazetteer, which includes information captured under statutory obligation through the SNN process.
-
The Royal Mail’s data, providing a Postcode Address File (PAF) containing the UDPRN and the delivery point address record.
-
The Valuation Office Agency, which provides cross references to council tax and non-domestic rates data.
OS Places API won’t find general areas (such as ‘forest’), or perform bulk address matches in its off-the-shelf form. However, if bulk matching could be useful to you, please let us know.
The geosearch resources – find the nearest, find within a specific radius, and find within a bounding box – all need X and Y coordinates entered in BNG (Eastings and Northings). However, postcode searches can be performed using only the area and district integers. For example:
-
SO16 0AS is the full postcode of our head office in Southampton. But searches for Ordnance Survey at SO16 will return details showing that our address is on Adanac Drive.
OS Places is a RESTful API, returning queries in either XML or JSON. The ‘find’ tool enables rapid searches of AddressBase Premium to discern ambiguous addresses, whereas the ‘match’ tool is for more granular matching and cleansing of existing address databases. There’s no need for any database management of AddressBase Premium itself.
The OS Places API accesses details of addresses in Northern Ireland, but these have a few unique characteristics due to not being derived from Address Base Premium. Addresses within Northern Ireland will not have a UPRN or status, and coordinates will be ‘0.0’ due to falling outside of the British National Grid.
At the OS APIs developer hub you'll find comprehensive guides, documentation and code snippets to help you start working with OS Places API as quickly as possible.
