I couldn't get the address finder tool to work after entering a dozen different versions of my address.
This website says it is available for my town, is it true?
The site states that it is potentially available, but I have never put a lot of faith into third party sites. Forums tend to be a better bet to find out where FiOS is if Verizon's website is not working right for you. Who is your local telephone company? If your telephone company isn't Verizon, but is another company such as AT&T you will not be able to get FiOS unless you live in an overbuild area, which are very rare and only appear where another telephone company controls a small section of lines in an area.
