Washington area code questions
How many area codes does Washington have?
Washington has 6 active geographic area codes in this directory: 206, 253, 360, 425, 509 and 564.
Which area code should I choose in Washington?
Start with the first three digits after +1 on the number you want to check. The codes in this directory are associated with places including Seattle, Tacoma, Vancouver, Bellevue, and Spokane. The listed places are examples, not a complete map of each code’s boundaries.
Which Washington area codes share coverage?
NANPA groups these codes in shared numbering complexes: 206 / 564; 360 / 564; 206 / 360 / 564. Members can serve overlapping areas; being in the same complex does not necessarily mean identical geographic boundaries.
How do I dial a number in Washington?
Open the individual area code to check its local dialing rule. For a phone lookup, enter +1 followed by the three-digit area code and the seven-digit number. A state or area code alone is not enough to look up a particular number.
Does an area code from Washington show where the caller is?
No. An area code describes a number’s assigned region. People can keep numbers after moving, use them while traveling, or place internet-based calls. Caller ID can also be spoofed, so the code does not confirm the caller’s location or identity.
