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).
Improve efficiency, guarantee accuracy and reduce costs. With OS Match & Cleanse API, you’ll have instant, reliable search results to make deduping and cleansing address data easier for your business.
For customer data managers, the address matching and cleansing tools in OS Match & Cleanse API let you build trust in your information. They make it simple to correct errors from misheard phone calls, for example, so you get fewer duplicate records.
Use postcodes and UPRNs or text strings to identify and match your targets – get information about residential and commercial properties quickly and easily.
OS Match and Cleanse 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 Match and Cleanse 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.
OS Match and Cleanse is a RESTful API, returning queries in either XML or JSON. The ‘match’ tool is for granular matching and cleansing of existing address databases. There’s no need for any database management of AddressBase Premium itself.
The OS Match and Cleanse 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.
