In 2009, area code 475 was introduced in Connecticut, overlapping with the existing area code 203. This overlay system allowed for a greater number of telephone numbers to be assigned within the same geographic area. Consequently, individuals in the same vicinity might have phone numbers with different area codes - one person might have a 475 area code, while their neighbor could have a 203. Cities such as Bridgeport, Danbury, New Haven, Norwalk, Stamford, and Waterbury all fall within the coverage of area code 475.
When it comes to zip codes, numerous codes exist within the area covered by code 475, reflecting the diversity and complexity of Connecticut's geography. Notable zip codes within this area include:
- 06501-06540 (New Haven)
- 06601-06699 (Bridgeport)
- 06701-06798 (Waterbury)
- 06801-06828 (Danbury)
- 06850-06860 (Norwalk)
- 06901-06928 (Stamford)
It's important to note that these zip codes may correspond to both area codes 475 and 203, resulting in an interesting overlap of numbers.
As of the 2021 census, the population of Connecticut is approximately 3.59 million people. The region within area code 475 is particularly populous, including major cities such as New Haven and Bridgeport. However, because of the area code overlay, it's not clear what proportion of residents have a phone number with area code 475.
The economy of the 475 area code region is diverse and robust, with key sectors including healthcare, education, manufacturing, finance, and insurance. Residents also have access to top educational institutions such as Yale University, University of New Haven, Southern Connecticut State University, and Fairfield University.
In addition to its economic advantages, the region offers a high quality of life, with numerous cultural and recreational opportunities. Residents can enjoy a range of activities, from exploring galleries, museums, and theaters, to outdoor activities such as hiking, kayaking, and golfing.
Overall, the introduction of area code 475 has expanded the telecommunication capacity of Connecticut, helping to accommodate the state's growing population. As the state continues to thrive, this dual area code system – 475 and 203 – ensures a rich diversity of telephone numbers for its residents.
