When you subscribe to a 1 state or 3 state plan you get the choice to pick states, regions, or a combination.
Regions are 125 mile radiuses around specific cities throughout the US. Most subscribers pick states because you usually get more territory.
Regions, however, are your best choice when you live in a city or area that is on the border of multiple states and you don’t want a 3 state plan.
For example, if you work in Omaha you might be better off with the Omaha Region which includes parts of 5 states within 125 miles, South Dakota, Iowa, Nebraska, Missouri, and Kansas! When you work near Dallas you might prefer the entire state of Texas compared to the Dallas Region which is only 125 radius around Dallas.
When you work in the northeast, a region might be your best option because most 125 mile radius regions in the northeast overlap multiple states. You can mix states and regions with a 3 state plan and when you choose nationwide you get everything!
