History of Area Code 203
When phone numbers became publicly available in 1947, the 203 area code was assigned to Connecticut.

After that, the area code 203 has been limited to southwestern cities of Connecticut, such as Bridgeport and New Haven.
The number of users surpassed again. So, in 2009, the 475 area code was added as an overlay to the existing 203 phone area code. This helped to address the new demand for telephone services for individuals and companies to establish better connections within different cities in Connecticut.
