Service-area businesses—are defined as businesses that serve customers at their locations—should have one page for the central office OR location and designate a service area from that point. Service-area businesses can't list a "virtual" office unless that office is staffed during business hours.
According to GMB support, one address (unique address and phone number) for one GMB page is allowed even if its the same business name as long as service areas do not overlap.
Not all businesses serve customers from a brick-and-mortar location or storefront. Some businesses operate from a home office or unlisted business address because they perform services at a client's home or location.
