The 203 area code<\/strong> is one of the oldest and most recognizable telephone area codes in the United States. Serving southwestern Connecticut, it has played a key role in the region\u2019s communications infrastructure for decades.

Origins and History<\/h3>\n\n\n\n

The 203 area code was established in 1947<\/strong>, making it one of the original North American Numbering Plan (NANP) area codes.

As population growth and increased telephone usage expanded over the years, the state required additional area codes to meet demand.<\/p>\n\n\n\n

In 1995<\/strong>, Connecticut was split, and the 860 area code<\/strong> was introduced to serve the northern and eastern parts of the state.
