Connecticut Zip Codes



Connecticut Connecticut is a state in the New England region of the northeastern United States. It is bordered by Rhode Island to the east, Massachusetts to the north, and the state of New York to the west and the south (with which it shares a water boundary in Long Island Sound).

Connecticut is named for the Connecticut River, the major U.S. river that approximately bisects the state. Its capital city is Hartford. Much of southern and western Connecticut (along with the majority of the state s population) is part of the New York metropolitan area; three of Connecticut s eight counties are statistically included in the New York City combined statistical area, the same area is widely referred to as the Tri-State area. Connecticut s center of population is in Cheshire, New Haven County, which is also located within the Tri-State area.

Connecticut is the 3rd least extensive, the 29th most populous, and 4th most densely populated of the 50 United States. Called the Constitution State, Nutmeg State, and "The Land of Steady Habits", Connecticut was influential in the development of the federal government of the United States.

ZIP codes are a system of postal codes used by the United States Postal Service (USPS) since 1963. The term ZIP, an acronym for Zone Improvement Plan, is properly written in capital letters and was chosen to suggest that the mail travels more efficiently, and therefore more quickly, when senders use the code in the postal address. The basic format consists of five decimal numerical digits. An extended ZIP+4 code, introduced in the 1980s, includes the five digits of the ZIP code, a hyphen, and four more digits that determine a more precise location than the ZIP code alone. The term ZIP code was originally registered as a servicemark (a type of trademark) by the U.S. Postal Service, but its registration has since expired.


ZIP codes designate only delivery points within the United States and its dependencies, as well as locations of its armed forces. There are no ZIP codes reserved for designating mail bound for foreign destinations (with the exception of U.S. military units stationed outside of the United States), and therefore, international outbound mail should not include a ZIP code in the delivery address. The last line of a foreign address must only show the name of the country of destination.
