Where can I locate a franchise business directory where I can search by state to find headquarter locations?

Question

Searching for franchises that have their headquarters in the state of Minnesota

Answer 1

Have you tried these?
Another option is look at retailers or industries by state, like the Food Marketing Institute (FMI) or the National Retail Federation (NRF), or Retail Direct or Retail Industry. These will identify companies that operate, or want to operate, in various states and enterprises. That helps you narrow things down to what fits your interest or ability.
