Find any 206- phone number in Washington
The 206 area code is part of the North American Numbering Plan (NANP) system, and is one of the original 86 area codes created in 1947. It is the area code for Seattle and the rest of western Washington state, as well as parts of Shoreline, Burien, Vashon, and Maury Islands. All phone numbers within the 206 area code have 10 digits, with a three-digit prefix followed by a seven-digit line number.
The North American Numbering Plan is a standardized system used to identify telephone numbers in the United States, Canada, and many Caribbean and Pacific Island nations. The system assigns each area a three-digit area code, which is then further divided into seven-digit local numbers. This allows each phone number to be identified as belonging to a particular geographic region, making it easier for long-distance calls to be routed correctly. The NANP is managed by the North American Numbering Plan Administration (NANPA), providing individual area codes to local usage entities like phone companies.
