History of the 206 Area Code

The 206 area code was one of the original area codes established in 1947. It initially covered the entire state of Washington. Over time, as the demand for telephone numbers increased, the area code underwent several changes:

  • In 1957, area code 509 was created to serve the eastern part of Washington.
  • In 1995, area code 360 was introduced to serve areas outside the Seattle metropolitan area.
  • In 1997, area code 425 was split from 206 to serve the northern and eastern suburbs of Seattle.
  • In 1997, area code 253 was also split from 206 to serve the southern suburbs of Seattle.

These changes were implemented to accommodate the growing population and the increasing need for telephone numbers. For more historical details, visit the North American Numbering Plan Administrator (NANPA).
