It works - we did it when Verizon said we were outside of their service area for FiOS even though our next door neighbors were all getting it. Two weeks later we got a call from the assistant for the dude who ran thing for our region, explaining that Verizon hired a third party company to map areas for service - and the third party company placed us in a town 5 miles away. It was fixed right then and there, and we got a good discount on our service for 2 years.
