Manhattan Private Investigator

New York's business services category holds 3,060 listings, and the contact fields on them are close to full. A phone number sits on 2,966 of those records and a website on 2,801. That is worth knowing before you start, because for most of this list you can read a firm's own site first and call second, rather than ringing around to work out what a company actually does.

The spread is lopsided. ZIP 10001 holds 173 of these businesses, more than any other; 10018 follows with 133, then 10016 with 97. If you already know which part of the city you need, filtering by ZIP will cut this list down faster than scrolling it. SiteCity does not inspect or rate the businesses it lists, so the order here is not a recommendation, and sponsored placements are labeled Sponsored wherever they appear. Owners can claim a listing and correct the phone number or website on it.
