Postcodes to Latitude and Longitude

Privacy

We think privacy is very important. If your file contains postcodes that constitute personal data, you might be worried about using a web-based tool like this. However, we have designed this tool to minimise the privacy implications. None of the raw data you enter here gets uploaded to our server; it stays in your web browser. Obviously, we have to do a postcode lookup so we do that by requesting an entire postcode block e.g. all of LS (Leeds) or all of BD (Bradford) at a time. That way we can find the coordinates for the postcode in your browser without our server knowing anything other than the broad area. You can also download a copy of this project to run entirely offline if that makes you feel more comfortable. You can also look at the source code to check what it is doing.

Alternative tools

• Add fields to CSV

  David Kane (Find that Postcode) has created a more comprehensive tool that can also add names and codes for other UK geographies such as LSOAs, Clinical Commissioning Groups, Parliamentary Constituencies and more.
