Why Choose a 475 Area Code?
As the 203 area code began to exhaust its available numbers, the 475 overlay was introduced in 2009 to provide continued availability. Rather than splitting the region or changing existing numbers, the overlay allows both 475 and 203 to coexist in the same geographic area. Whether your number starts with 203 or 475, your business can operate across southwestern Connecticut with full local recognition and flexibility. Major cities in the 475/203 area code region include: Bridgeport, Stamford, New Haven, Norwalk, Danbury, Westport, and Greenwich. A 475 number helps your brand appear local, familiar, and ready to serve customers across a vibrant economic corridor.
