I am new to GIS. I have a list of postcodes and I have to make a map, basically to show distance from a specific area. Concentric ring pull type of map. I don't know how to get my postcodes into a format where I can add them to a GIS map. I am using QGIS.
You can download Code-point Open from https://www.ordnancesurvey.co.uk/business-and-government/products/code-point-open.html to get a coordinate of each postcode unit that you can join to your existing postcodes.
