Bridgeport, CT Area Codes

Area codes serving Bridgeport

Bridgeport sits in Connecticut, part of the Northeast region and the Eastern Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 203, 475.

The original code is 203 (in service since 1947). As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.

How to pick an area code for a new number

When you activate a new line in Bridgeport, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 203), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.

Dialing in Bridgeport

Because Bridgeport is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in Connecticut, visit the Connecticut area codes page.
