[1] From 1963 to 1983, the MSA also included neighboring Susquehanna County in Pennsylvania,[3] part of which still falls in the Binghamton, NY–PA Urban Area.

[5] The Greater Binghamton name was adopted in the early 21st century to better identify the region with its most well-known city in efforts of marketing and external promotion.

While "triple cities" strictly covers only the three main municipalities, the term also refers broadly to the surrounding area of conurbation, including Endwell, West Corners, the Upper Front Street area (technically in the town of Dickinson), and the town of Vestal.

The core municipalities of Binghamton, Johnson City, and Endicott are connected together by the Southern Tier Expressway (NY 17, future Interstate 86).

Main Street (NY 17C) is connected as a single road through much of the urban core, beginning in downtown Binghamton and running through Johnson City, Endwell, and Endicott.

The Greater Binghamton Airport is located in the Town of Maine, just north of the Village of Johnson City.
