Quick answer

Bridgeport ZIP code footprint
How Bridgeport's ZIP footprint compares with national norms.
7 ZIP codes are listed for Bridgeport, covering a population of 148,654. They span 9 numbers, 06604 through 06612. The median covered metro on this site lists 12 codes; Bridgeport ranks 78 of 94 by count. Large metros carry more codes because USPS splits a delivery area once carrier volume outgrows one route cluster, not because the city is geographically bigger.
All 7 codes share the 066 prefix. That first trio is the sectional center facility — the USPS plant that sorts mail for the region — so every piece addressed to Bridgeport passes through one facility. The range runs 06604 to 06612.
ZIP boundaries are carrier routes, not city limits. USPS redraws them when delivery volume shifts; Connecticut redraws tax and municipal lines on a different schedule entirely. A Bridgeport mailing address does not prove an address sits inside Bridgeport city limits, and a single code can straddle the boundary.

Why ZIP-based rate lookup is unreliable
USPS redraws ZIP codes when carrier routes change. Tax jurisdictions move with annexations, county lines and voter-approved districts. The two never line up. In Connecticut, even without local add-ons, remote sellers should validate the full delivery address against the Connecticut Department of Revenue Services lookup at the time of sale.
