Postcodes to Latitude and Longitude

Have you got a CSV file with Postcodes and want to add Latitudes and Longitudes? Let us help with that. Add a CSV file below with a column titled Postcode and we'll add in Latitude and Longitude columns for you (or update them if they are empty).

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.
