Your business's phone number is how customers, both existing and new, will contact you. You do not want to change it for any reason because it can be difficult to contact all of your customers to have them update your phone number. The Federal Communication Commission has "local number portability" rules that allow you to take your phone number with you when you change addresses or phone providers, as long as you are in the same area.
