Introduction To Area Code 520
520 is a geographic area code for Tucson, Arizona and its suburbs.The 520 area code was created on October 7, 1997, as a split from area code 602. It originally covered the southeastern corner of the state, from the New Mexico border to the town of Marana, just north of Tucson.
In 2001,520 was extended to cover most of the Tucson metropolitan area, including the city of Oro Valley.

Regions That Use 520 As Area Code
There are many different area codes in use throughout the United States, and each one has its own unique set of quirks and characteristics. One of the most interesting area codes is 520, which is used in a number of different regions throughout the country.520 is a unique area code in a few ways. Firstly, it is one of the few area codes that is split between multiple states. Specifically, 520 is used in Arizona and New Mexico. This can lead to some confusion, as people in different states may not be familiar with the other state's 520 area code.
Additionally, 520 is one of the few area codes that is not assigned to a specific city. Instead, it is used in a number of different rural areas. This can be both good and bad, as it means that there is more flexibility in terms of where you can use the 520 area code, but it also means that there is less certainty about what specific area you are calling.
Overall, the 520 area code is a fascinating example of how different regions in the United States use different area codes to reflect their unique character.
