@Juan_Felipe_Devia_Ro Thank you for inquiring. The .csv file available on the portal has string indications for the geographical limits of the polygons that define each postal code. To reference that information in order to obtain a GIS data set with geographical limits, post codes and address is not a trivial process at all. By the contrary, it can be extremely time consuming and furthermore, due to processing errors one might not even get the exact same file that I can see on the portal. If along side the available .csv, there would be a shapefile or whatever GIS data format, it would be a different thing.
Regarding the license, thank you very much for pointing that out! I agree. Please let me know if there is a possibility of obtaining the data as is on the portal, with the geometries of the postal codes. Cheers!
