Understanding the 203 Area Code: Everything You Need to Know

The 203 area code is one of the original area codes introduced in 1947 under the North American Numbering Plan (NANP). Covering parts of Connecticut, it has long been a hub for business, residential growth, and vibrant cultural exchanges. This blog delves into the specifics of the 203 area code, its business relevance, and highlights influential executives in the region.


Where Is the 203 Area Code Located?

The 203 area code serves southwestern Connecticut, including prominent cities like Bridgeport, Stamford, New Haven, and Waterbury. It encompasses bustling urban centers and suburban neighborhoods, making it a versatile area for commerce and residency.

In 1995, to accommodate growing demand, the 475 area code was introduced as an overlay. Both codes now serve the same geographic region.
