The USDA issued a new zone map!

I was checking Stark Bros and they did change my zone from 5b to 6a. That being said my zip code is shared with part of Genese Colorado. My dad had the same zip as my mother and those two places are far different

Instead of searching by zip code you can just zoom in on the map and keep zooming in until you can see your immediate area:
