SAP Leonardo Center, New York

New York has 222 engineering services listings on SiteCity, spread from Midtown zip codes down to Brooklyn's 11201. That's too many to scroll through one by one, so most people narrow by zip first, then check which listings have working contact info before picking up the phone.

Zip 10018 alone carries 31 of these listings, with clusters also sitting in 10001 and 10017. Most entries include a phone number, and most list a website too, so you can usually check a firm's site before calling. None of these listings are labeled Sponsored, since paid placement hasn't launched for this category in New York, so the order you're browsing is unpromoted directory data, not a ranked lineup. If you run one of these firms and the listing is missing a website or shows a wrong number, you can claim it and update the details, which helps a client in your zip actually find you instead of giving up.
