History of the 203 Area Code
The 203 area code was established in 1947 as one of the original codes introduced under the NANP. Initially, it covered the entire state of Connecticut.
Key Milestones
- 1995: Rapid population growth and increasing demand for phone numbers led to the introduction of the 860 area code, which split off to serve the northern and eastern parts of Connecticut.
- 2009: The 475 overlay was added to the 203 area code region, ensuring a continuous supply of new phone numbers without disrupting existing ones.
These changes allowed the 203 area code to continue serving the southwestern region of Connecticut while accommodating modern communication needs.
