FAQs

How is this data supplied and what do I need to use it?

OS Open Names is available to download as a single file covering the whole of Great Britain. It’s available in two formats, CSV and GML3. You can also get it on DVD or access the data via OS Names API. You’ll need geographic information system (GIS) software to use the data.

Does OS Open Names give the locations of houses?

No, it doesn’t go down to the level of individual houses, but it does show the location of roads. It also tells your GIS how far to zoom out to show the full length of your street. For property locations, you would need one of our AddressBase products.
