I'm looking for a service that converts Postal Code of Major European Cities to Geo Shapes (List of Lat/Lng) pairs like when you go to Google Maps and type for examples 10557 Berlin, and it draws boundaries around the are for that Geo-Code.
I found some Hacky ways to use the official Maps for this, But I don't wanna rely on that. is there a paid service or downloadable files that has such data.
Given that I don't want Postal Code to (1 Center Point Lat/Lng) but instead to a lit of points to form the shape for that Postal Code.
