History of Area Code 959
Area code 959 was established as an overlay for area code 860. The Connecticut Public Utilities Regulatory Authority approved the overlay in 2013, and area code 959 entered service on August 30, 2014. New numbers in the region could then be assigned either 860 or 959.
Area code 860 itself was created in 1995 in a split from area code 203. The 959 overlay was added because the 860 region needed more phone numbers as wireless phones and other services increased demand. Since the overlay began, 10-digit dialing has been required for local calls in the 860 and 959 service area.
