About Connecticut’s ZIP codes

Of Connecticut’s ZIPs, 271 are standard ZIP codes for street delivery, while 111 serve PO Boxes only and 40 belong to a single organization such as a university, a hospital, a large company or a government office. On the map 288 ZIPs have outlines; the other 134 are drawn as dots, because they cover no area of their own, and they have no residents counted in the Census.

The ZIPs are spread over 8 counties and 269 postal city names. Hartford County has the most, 108 (26% of the state’s), followed by New Haven County with 78 and Fairfield County with 77. Tolland County has the fewest, 20 ZIPs.

The postal city with the most ZIP codes is Hartford, with 36. The most populous is Bridgeport, with 148,646 people across its 10 ZIPs. 26 of its postal cities are among the 2,000 most populous in the country, from Bridgeport down to Torrington.

The most populous is 06902 in Stamford, with 69,192 residents, followed by 06010 in Bristol with 60,748. Half of the 288 ZIPs with residents have more than 8,298 people and half fewer. 5 ZIPs have 50,000 residents or more, while 34 have fewer than 1,000.

Largest first by 2020 population; “–” marks ZIPs with no residents of their own.

About these numbers

Population is the 2020 Census count for each ZIP Code Tabulation Area, the Census Bureau’s outline of the area a ZIP code delivers to. ZIP codes for PO Boxes and single organizations have no area of their own, so they count as zero. City names are postal city names (the name the Postal Service prefers on mail), not city limits, so a suburb with its own post office is counted as its own city.

Each ZIP is counted in the one county that holds most of its outline; ZIP codes do not follow county lines, so a few reach partly into a neighbor.

The map above opens with all 422 selected and framed. Click or tap a ZIP to drop it or add a neighbor, draw a circle or lasso to add more, then press Copy list or Download in the list panel to take the ZIP codes of Connecticut into a spreadsheet, an ad platform or a mailing tool.
