605 Area Code

Introduction To Area Code 605

Area code 605 is one of the original area codes established in 1947. It covers the western two-thirds of South Dakota. 605 is a relatively small area code, and it has remained largely unchanged since its inception. However, with the growth of the Internet and cell phones, it is becoming increasingly difficult to assign new phone numbers that fall within 605's coverage area.

If you're looking for a new phone number and you live in the western part of South Dakota, you may want to check to see if it's available in area code 605. Otherwise, you may have to go with a new area code.
