The area code 475 is located in Bridgeport, Connecticut.
Area code 475 serves Bridgeport, Connecticut, and the wider southwestern shoreline, sharing the same geographic footprint as area code 203. This overlay covers a dense, coastal region along Long Island Sound, where Bridgeport anchors a busy metro area known for shipping, higher education, and arts. The overlay was activated in December 2009, which introduced mandatory 10‑digit dialing for all local calls in the 203/475 area. New phone numbers in this region may be assigned the 475 area code, while existing 203 numbers stay the same.
Major cities and communities in the 203/475 area include:
From Bridgeport’s working harbor and ferry link to Long Island to New Haven’s Yale University and Stamford’s corporate centers, the 475/203 region blends history, education, and commerce. Key landmarks include the Port Jefferson Ferry in Bridgeport, Beardsley Zoo, Seaside Park, the New Haven Green, and the Long Island Sound shoreline. Because 475 is an overlay, both 203 and 475 numbers appear on caller ID in the same neighborhoods, which helps meet demand without changing boundaries. For anyone dialing, remember: 10-digit dialing is required across the entire 203/475 service area.
“Bridgeport is Connecticut’s largest city.” — U.S. Census Bureau
Interesting note: Connecticut first launched 203 in 1947 and later split 860 in 1995; 475 was then added as an all-service overlay to relieve 203 in 2009. Today, area code 475 connects callers across a compact, high-traffic corridor that includes major highways (I‑95, Route 15/Merritt Parkway) and busy rail lines, making it central to life and business in coastal Connecticut.
