I put in my zip code on their web site to see if they had coverage. They force you to enter your email address as well and they make sure it's a valid domain.

After I entered my zip code and (fake) email address it told me that they needed my physical address to determine if they had coverage for me at my exact address. Thinking they had coverage in my zip code, I entered a real (but not my) address. Then they immediately said that coverage was not available at my address and to look at their map for more coverage details.

Looking at their map, it looks like coverage is not within 500 miles of any part of my zip code. I guess this is just another part of their gathering of personal information for making a simple inquiry.
