Why Choose a 203 Area Code?
The 203 area code covers Southwestern Connecticut, including major cities like Stamford, New Haven, Bridgeport, Norwalk, and Danbury. It was one of the original area codes created in 1947 and is deeply associated with the state's financial, academic, and healthcare centers.
Due to the limited availability of 203 numbers, 475 was introduced as an overlay. Both codes now serve the same area, so whether you get a 203 or 475 number, your business will have strong local recognition in Southern Connecticut.
