Half the valley's addresses say Las Vegas and sit in unincorporated Clark County
Your Business Profile, your citations and your service pages should follow the jurisdiction lines the valley actually uses, not the one word printed on your envelope.
Much of the developed valley, including the Strip corridor, sits in unincorporated Clark County rather than in the City of Las Vegas. Paradise, Spring Valley and Enterprise are names people use in conversation and type into a search bar. Where your own office falls is worth confirming with the county or your landlord before you publish anything.
The practical work is dull and it matters. One address format everywhere. A primary Business Profile category that matches the work you want, not the widest one available. Service areas set to the places you will actually take a call from, and hours that reflect when a human answers.
Henderson and North Las Vegas deserve their own pages only if you can say something true about serving them: an office, a regular appearance, a staff member who works from that side. A page that swaps a city name into the same paragraph is a page a searcher can smell.
Do not rent a mailbox and call it an office. Profile suspensions are a slow, expensive problem to unwind, and a firm whose credibility is its whole product should not be gambling that one.
