Montana Zip Codes



Montana Montana is a state in the Western United States. The western third of Montana contains numerous mountain ranges. Smaller "island ranges" are found in the central third of the state, for a total of 77 named ranges that are part of the Rocky Mountains. This geographical fact is reflected in the state s name, derived from the Spanish word montaña (mountain). Montana has several nicknames, none official, including: "Big Sky Country" and "The Treasure State", and slogans that include "Land of the Shining Mountains" and more recently, "The Last Best Place". Montana is the 4th-most extensive, but the 7th-least populous and the 3rd-least densely populated of the 50 United States. The economy is primarily based on services, with ranching, wheat farming, oil and coal mining in the east, and lumber, tourism, and hard rock mining in the west. Millions of tourists annually visit Glacier National Park, the Little Bighorn Battlefield National Monument, and three of the five entrances to Yellowstone National Park.

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.
