How to Search Craigslist postings
Craigslist has added a mapping feature that plots the location and displays a popup box of the listings you’ve searched. Query terms that appear within Craigslist housing offerings and view the location on a map. You can search by any term that appears in the ad, or by town, street or zip code to identify all the housing in the area.
This image shows the listing I searched by telephone number. The mapping feature was also displayed in New York for items for sale, personals and community.
