Zip Code - County

[tsykes]

The zip code to county matching in broadband_data_zipcode.csv seems a bit erroneous. There are duplicates of zip code by county which initially seems ok because zip codes don't follow county boundaries. But, for example, 56318 shows to be in 27153 (Todd County) and 27111 (also Todd County but should be Otter Tail County) but in reality it is in 27153 (Todd County) and 27097 (Morrison County). Perhaps your lookup is coming from a kind of geoip location but sometimes the county seems to be wrong for a zip code. Perhaps you meant this to be a distinct list of postal codes and the duplicates are unintended. They only exist in AK, MN, and SD.
