A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of administrative regions of the public switched telephone network (PSTN) and they are also present in private telephone networks. For public number systems, geographic location plays a role in the sequence of numbers assigned to each telephone subscriber.
Michigan is a state in the Great Lakes and Midwestern regions of the United States. The state's name, Michigan, originates from the Ojibwe word mishigamaa, meaning "large water" or "large lake". With a population of about 10 million, Michigan is the tenth most populous of the 50 United States, with the 11th most extensive total area, and is the largest state by total area east of the Mississippi River. Its capital is Lansing, and its largest city is Detroit. Metro Detroit is among the nation's most populous and largest metropolitan economies.
The Lower Peninsula of Michigan is the southern of the two major landmasses of the U.S. state of Michigan, the other being the Upper Peninsula. It is surrounded by water on all sides except its southern border, which it shares with Indiana and Ohio. Although the Upper Peninsula is commonly referred to as "the U.P." it is fairly uncommon for the Lower Peninsula to be called "the L.P."
It was created in June 1999 as a split from area code 616. 231 is essentially the northern half of the old 616 area code. 616 previously covered the entire western half of the Lower Peninsula, extending west from the north-south line aligned with the Mackinac Bridge. Generally, 231 includes the western half of the territory generally defined as Northern Michigan. Muskegon is usually defined as being part of West Michigan, but now uses 231 rather than 616.
Area code 616 is the North American Numbering Plan (NANP) area code for the west-central portion of the Lower Peninsula of Michigan. The area code is centered around Grand Rapids, and also includes Holland, Greenville, and Grand Haven. It includes all of Kent and Ottawa counties, and parts of neighboring counties, including the western and central parts of Ionia County.
The Mackinac Bridge is a suspension bridge spanning the Straits of Mackinac to connect the Upper and Lower Peninsulas of the U.S. state of Michigan. Opened in 1957, the 26,372-foot-long bridge is the world's 20th-longest main span and the longest suspension bridge between anchorages in the Western Hemisphere. The Mackinac Bridge is part of Interstate 75 and the Lakes Michigan and Huron components of the Great Lakes Circle Tour across the straits; it is also a segment of the U.S. North Country National Scenic Trail. The bridge connects the city of St. Ignace on the north end with the village of Mackinaw City on the south.
Northern Michigan, also known as Northern Lower Michigan or Upper Michigan, is a region of the U.S. state of Michigan. A popular tourist destination, it is home to several small- to medium-sized cities, extensive state and national forests, lakes and rivers, and a large portion of Great Lakes shoreline. The region has a significant seasonal population much like other regions that depend on tourism as their main industry. Northern Lower Michigan is distinct from the more northerly Upper Peninsula and Isle Royale, which, obviously, are also located in "northern" Michigan. In the northern-most 21 counties in the Lower Peninsula of Michigan, the total population of the region is 506,658 people.

A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.

US Highway 31 (US 31) is a part of the United States Numbered Highway System that runs from Alabama to the Lower Peninsula of the US state of Michigan. In Michigan, it is a state trunkline highway that runs from the Indiana–Michigan state line at Bertrand Township north to its terminus at Interstate 75 (I-75) south of Mackinaw City.

Along its route, US 31 has been dedicated in memory of a few different organizations, and sections of it carry the Lake Michigan Circle Tour (LMCT) moniker. Four bridges used by the highway have been recognized for their historic character as well.
The Gogebic Range is an elongated area of iron ore deposits located within a range of hills in northern Michigan and Wisconsin just south of Lake Superior. It extends from Lake Namakagon in Wisconsin eastward to Lake Gogebic in Michigan, or almost 80 miles. Though long, it is only about a half mile wide and forms a crescent concave to the southeast. The Gogebic Range includes the communities of Ironwood in Michigan, plus Mellen and Hurley in Wisconsin.
Michigan consists of two peninsulas that lie between east longitude, and are separated by the Straits of Mackinac, and some nearby islands. With the exception of two small areas that are drained by the Mississippi River by way of the Wisconsin River in the Upper Peninsula and by way of the Kankakee-Illinois River in the Lower Peninsula, Michigan is drained by the Great Lakes-St. Lawrence watershed and is the only state with the majority of its land thus drained.
