Just in case you didn’t know, 906 is the only area code for the entire Upper Peninsula of Michigan. In addition, 906 is the largest area code in Michigan.
On March 19th, 1961, area code 906 was created as a split from what was then area code 616. Currently, according to Wikipedia, the area code is not expected to be exhausted until 2023.
Area code 906 is the 6th largest area code east of the Mississippi River. Although it is one of the largest area codes by land area, it is one of the smallest area codes in terms of population. Here are the five area codes with a larger land area than 906 east of the Mississippi…
- 207 – The entire state of Maine
- 304 – The entire state of West Virginia
- 662 – The northern half of Mississippi
- 217 – Central Illinois
- 715 – The northern half of our neighbor, Wisconsin
Though one of the biggest in the East, 906 doesn’t stand a chance in size when competing against the area codes of the Western United States. The states of North Dakota, South Dakota, Montana, Wyoming, Idaho, and New Mexico all have just a single area code for the entire state. To add to that list, the largest area code of all, is area code 907, of the great state of Alaska. Ironically, it’s just one digit area from our area code of 906.
In addition, nearly every state west of the Mississippi has an area code that’s larger than 906.
Hawaii, Delaware, Rhode Island, New Hampshire and Vermont also have their own area codes, though not as big as 906. That makes a total of 14 states to have a single area code.
