Finding fax number of local businesses

Question

I would like to fax to all the chiropractors in my neighbourhood. However, I am not able to easily find the fax numbers to those businesses. I tried phonebook, google search, etc. Is there a way to find the fax number of all the people in my neighbourhood? I am not trying to spam them, just reach them for a non-profit purpose.

Thanks. Your response is appreciated.

Answer 1

What city and state are you in?  Try a search for "fax directory" for your location.
