On this page you'll find product supply information for OS Open UPRN, including available formats, the supply mechanism and the currency.
The OS Open UPRN product is available as either a comma-separated values (CSV) file or GeoPackage (GPKG) file.
OS Open UPRN is supplied for the whole of Great Britain as a single CSV file containing all records.
CSV files are a delimited text file that uses commas or other characters to separate individual elements of a feature. It is used to store data, often in the form of a table. These tables can be freely loaded into databases and programs, allowing for the easy loading and updating of data holdings.
The CSV format of OS Open UPRN means:
Column headers will be included in the file.
There will be one record per line in each file.
Fields will be separated by commas.
No comma will be placed at the end of each row in the file.
Records will be terminated by Carriage Return / Line Feed.
OS Open UPRN is supplied as a single GeoPackage for the whole of Great Britain.
GeoPackage (GPKG) is an open standard data format as defined by the Open Geospatial Consortium (OGC). GeoPackage is designed to be a lightweight format that can contain large amounts of varied and complex data in a single, easy-to-distribute and ready-to-use file.
Please be advised that older versions of GIS software may need updating before being able to display and interact with GeoPackage files.
GeoPackage offers users the following benefits:
The single file is easy to transfer and offers the end-user a rich experience.
Attribute names are not limited in length, making it user-friendly.
The file size limit is very large at 140TB, so lots of data can be easily accommodated (please note that a file size limit may be imposed by the file system to which the file is written).
It supports raster, vector and database formats, making it a highly versatile solution.
It is an OGC standard.
In most cases, it is a plug and play format.
For information on how to open, use and understand a GeoPackage dataset, please refer to our ‘Getting Started with GeoPackage’ guide. Further detailed information on GeoPackage can be taken from the GeoPackage website.
OS Open UPRN is supplied as a free online download and is available without registration from the OS Data Hub. You can select a data format during the download process; depending on which format you choose, you will receive a single file containing either all records with headers already included (CSV) or the structure already defined (GeoPackage).
