Area Code 313

Where Is Area Code 313?

Updated: January 20th 2021

Area code 313 is found in Michigan and primarily serves the city of Detroit and most of its closest suburbs in Wayne County. Brought into effect on January 1, 1947, area code 313 was one of the original area codes in Michigan. Due to the demand for new telephone service, area code 810 was formed as a split from area code 313 in 1993. Just a few years later, area code 313 was again split to form area code 734 in 1997. Area code 679 has been reserved as a future overlay for when area code 313 becomes exhausted.

Detroit is a city in area code 313 and is the most populous city in Michigan. It is the fourth largest city in the Midwest and is the county seat of Wayne County. Detroit’s metropolitan area, Metro Detroit, is home to about one-half of Michigan’s population. The city is a major port on the Detroit River while the Detroit Metropolitan Airport is one of the most important hubs in the United States. Detroit has three international border crossings linking the city to Windsor, Ontario; they are known as the Ambassador Bridge, the Michigan Central Railway Tunnel, and the Detroit-Windsor Tunnel.

Looking back in time, Detroit had a very rich history. French colonists founded Detroit on July 24, 1701. During the 19th century, Detroit was a major port and transportation hub at the center of the Great Lakes region. In 1903, Henry Ford established the Ford Motor Company; other automotive pioneers included Walter Chrysler and the Dodge Brothers. As a result, Detroit became the world’s automotive capital in the early 20th century, allowing Detroit to become a significant metropolitan region. In the 1950s and 1960s, suburbanization continued with construction of an extensive highway and freeway system. However, from the late 20th century to the present, Detroit suffered a long economic decline, resulting in a significant decrease in the population. In 2013, a financial emergency was declared and then Detroit became the largest U.S. city to file bankruptcy. Today Detroit has an estimated population of 713,777 (2010 Census). Since 1950, the population has continuously been dropping, which in turn has led to many abandoned homes and commercial buildings. Detroit has high rates of poverty due to the loss of industrial and working class jobs; the mean income of the city is below the overall U.S. average. Unfortunately Detroit has one of the highest violent crime rates in the United States. In 2015, almost half of the murders in Michigan occurred in Detroit.

The racial makeup of the city is 82.7% Black, 10.6% White, 6.8% Hispanic, and 1.1% Asian. It is interesting to see that Blacks make up 82% of Detroit’s population but yet only make up 13% of Michigan’s population.

Detroit is known for its variety of architectural styles, including postmodern Neo-Gothic spires and Art Deco skyscrapers. While the majority of the city is made up of of low-rise structures and single-family homes, the Downtown and New Center areas consist of high-rise buildings. There are many neighborhoods and districts in Detroit that were constructed prior to World War II. Architecturally significant cathedrals and churches in Detroit include the Sweetest Heart of Mary and the Cathedral of the Most Blessed Sacrament. Recently the city has redeveloped the downtown area to revitalize parts of the city.
