Hi,
I am trying to merge polygons with the same feature (postal code) into a single polygon, so that in the end all polygons will have a unique postal code. However there are 50,000 unique postal codes so I am unable to do this manually by going into the attribute table and selecting all polygons with the same postal code and then merging them. There must be someway to go about this without doing it manually.
Also, polygons with the same postal code are not necessarily adjacent to each other.
Any advice would be helpful.
Thanks
