I still must be doing it wrong, because all I'm getting are the points within the SWIS code boundary and not the points outside the SWIS code area with the SWIS code (wrong GPS coordinates). I get what you're saying now, but I'm sure there's a attribute error with my shapefiles that's messing it up. Regardless, this way is still time consuming because I would have to go through each city/town/village to get it completed. My boss really just wants it simple: Plug in a code, and it spits out all the errors. Only way I could do that is if I had GIS programming knowledge which I don't...
Another issue I'm having is that my points are NAD27 and the shapefiles are NAD83 but yet they're projecting together which makes no sense, but that's for another time haha
