Why I am asking these questions is because What I would like to do is franchise or sell the domain names with different addresses but keep the phone number for administrative and billing purposes so I can control or charge for phone calls or leads. Also, if one of the owners/franchisees are away on vacation or busy, I can move or pull another one out of their territory and have them do work outside their region. So to review: different domains different name different address but same phone number.

Just wanting to know if it is beneficial to use a different phone # for each related business but not exactly the same region.

handyman business for each quadrant - different domain like:

cityNWhandyman.com cityNEhandyman.com citySWhandyman.com citySEhandyman.com

So 4 related domains but using 1 phone number. 888-555-1212 or should there be a different phone number for each different domain?

Looking forward to seeing your answer

Thank you.
