This was not my original though, but I have found it useful (and mentioned in a sprinkling of places) to think of ZIP codes as a sort of routing algorithm meant to facilitate the efficient movement of mail through the USPS infrastructure. Their history is quite interesting and supports this interpretation, especially with automation and the extensions to 9- and 11-digit codes. > Now I have to wonder if ZCTAs are still around and if they are mapped.

Considering how OSM wants to (and to some decent extent, does) denote census areas as quite distinct from the "OSM-usual" key:value pairs for conurbations, and ZCTAs blend ZIP codes and census boundaries, you'd muddy a lot of water by using ZCTAs, especially as you use OSM data. I, too, (like Clifford) wish you good luck and hope you have fruitful results you might share with us here at the completion of your project.

Ray, As you learned from Spencer Alves, postal codes are not areas. As far as I know there are no zip code areas in OSM. I would recommend using QGIS and Postgis to construct your queries using OSM and TIGER zip code boundaries. Are you looking for any broadband connectivity, just cellular, DSL, fiber, satellite, or a combination of all of them? My experience is that cellular maps often overstate their reach. Satellite internet service isn't really that great because of the lag time involved. (Upcoming low earth orbit communications satellites promise break thoughts ) Your project is interesting. I hope to read about your conclusions. BTW - I do have friends that only get internet service via their cell phones. Another even used to live off the grid on purpose. When we went looking for a place in rural Washington, we definitely had to exclude places that either didn't have internet service or the cell service was non-existent.

Zip Codes are Not Areas http://www.georeference.org/doc/zip_codes_are_not_areas.htm Specifically for Zip codes, the best you could do is query for addr:postcode. > On Jun 24, 2020, at 2:33 PM, Ray Kiddy wrote: > > Hello - > > I am interested in where people in the US lack internet connectivity and I > keep thinking that I should be able to use OSM for some part of this. > > I am recalling (perhaps not accurately) that connectivity information is > published by the FCC and I think that at least some of the information is per > zipcode. > > This led me into a bit of a rat hole as I sought to find out if there are > relations for zipcodes in the US.

Wow. Bizarre, but good to know. Yes, I _always_ have thought that zipcodes partition land areas. Now I have to wonder if ZCTAs are still around and if they are mapped. I expect not. much thanx - ray On 6/24/20 2:39 PM, Spencer Alves wrote: Zip Codes are Not Areas http://www.georeference.org/doc/zip_codes_are_not_areas.htm Specifically for Zip codes, the best you could do is query for addr:postcode.
