Massachusetts Zip Codes



Massachusetts Massachusetts, officially the Commonwealth of Massachusetts, is a U.S. state in the New England region of the northeastern United States of America. It is bordered by Rhode Island and Connecticut to the south, New York to the west, and Vermont and New Hampshire to the north; at its east lies the Atlantic Ocean. Massachusetts is the 7th least extensive, but the 14th most populous and the 3rd most densely populated of the 50 United States. The commonwealth features two separate metropolitan areas: Greater Boston in the east and the Springfield metropolitan area in the west.

Approximately two thirds of the commonwealth s population lives in Greater Boston, most of which is either urban or suburban. Western Massachusetts features one urban area – the Knowledge Corridor along the Connecticut River – and a mix of college towns and rural areas. Many of Massachusetts towns, cities, and counties have names identical to ones in England. Massachusetts is the most populous of the six New England states and has the US s sixth highest GDP per capita.

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.
