Find any 425- phone number in Washington
The 425 area code is associated with the state of Washington in the United States. It is one of the original area codes created on January 1, 1947 as part of the North American Numbering Plan and was assigned to the entire state of Washington. The plan is a uniform system for assigning telephone numbers across the state, with each number made up of a three-digit area code and a seven-digit subscriber number. The 425 area code service area covers the east side of the state and includes most of the suburbs of Seattle. It is currently overlaid by a second area code in the 206/360/564 overlay, with the second area code assigned to areas of the state east of Interstate 5.
The North American Numbering Plan is an integrated telephone numbering system that is regulated by the Federal Communications Commission. It requires telephone numbers originating in the United States to have a three-digit area code followed by a seven-digit subscriber number. The area codes are organized geographically, with each one representing a particular area of the country. This allows carriers to efficiently route calls to the appropriate area. The 425 area code is also associated with local exchange carriers such as AT&T, Frontier Communications, and Windstream.
