Almost every real estate agent SiteCity lists in New York can be reached straight from the listing. Of the 2,780 records here, 2,743 carry a phone number and 2,475 carry a website. The usual problem with this category is not finding contact details; it is working out which of 2,780 people to spend a call on.

One ZIP sits well ahead of the rest. 10022 holds 125 agents. The next busiest, 10011, has 73, and the counts fall to 55 in 11375 and 53 in 10023 after that. Read those as office addresses rather than territories: an agent listed in 10022 may work half of Manhattan, and one listed in 11215 may know four blocks of Brooklyn better than anybody. Ask where they closed their last few deals. SiteCity does not vet agents or rank them by results, and sponsored placements are labeled Sponsored wherever they appear. An agent or brokerage can claim a listing and correct the details on it.
