206 Area Code: Seattle Phone Numbers and the 564 Overlay
The 206 area code is the telephone code for Seattle in Washington State, in the northwest corner of the United States. If a missed call on your phone starts with +1 206, it came from a number registered in or around Seattle. The code has a long history, and in 2025 it went through its biggest change in decades when a second code, 564, began to be handed out in the same area.
This guide explains where the 206 area code reaches, how it came about, what the overlay means for people who live there, and what Indian readers should know when calling Seattle or receiving a call from it.

Where the 206 Area Code Reaches
Today 206 is a compact area code. It covers the city of Seattle and a handful of neighbouring places on the eastern shore of Puget Sound:
- Seattle itself, from downtown and Capitol Hill to Ballard, the University District and West Seattle
- Shoreline and Lake Forest Park to the north
- Woodway, the northern edge of the area
- Burien, Tukwila and parts of south King County down to Des Moines
- Mercer Island in Lake Washington
- Bainbridge Island and Vashon Island across the water
The boundaries follow old telephone exchange areas, called rate centres, rather than city limits. That is why a few streets near the edges use a neighbouring code instead.
Nearby codes cover the rest of the region. 425 serves the eastern suburbs such as Bellevue, Redmond and Everett. 253 covers Tacoma and the area to the south. 360 takes in much of western Washington outside the metro core, and 509 covers the eastern half of the state.
How the 206 Area Code Came About
In 1947 the American telephone system created the North American Numbering Plan, a set of three digit area codes that let operators route long distance calls. Washington State received a single code, 206, for the whole state.
As population and phone lines grew, the state was split again and again:
| Year | Change |
|---|---|
| 1947 | 206 created for all of Washington |
| 1957 | 509 split off for eastern Washington |
| January 1995 | 360 split off for much of western Washington |
| 25 April 1997 | 253 and 425 split off around Tacoma and the eastern suburbs |
| 2017 | Ten digit local dialing required in western Washington |
| 15 June 2023 | State regulator approves the 564 overlay for 206 |
| 10 June 2025 | New 564 numbers begin to be assigned in the 206 area |
Each split meant some people had to change the code on their letterheads and shop signs. By the late 1990s, 206 had shrunk to Seattle and its closest neighbours, and in Seattle culture the number became something of a local badge. Musicians, cafes and sports fans still use 206 as shorthand for the city.
The 564 Overlay Explained
Seattle’s growth as a home for large technology firms, hospitals and universities meant more phones, tablets, smart watches and business lines. The pool of available 206 numbers started to run low.
Rather than split the area again, the Washington Utilities and Transportation Commission chose an overlay. That means a second code, 564, now covers the same ground as 206. Nobody had to change an existing number. Instead, some new lines issued since 10 June 2025 begin with 564 even though the person lives in central Seattle.
The 564 code was already in use as an overlay for the 360 area, so the change mostly extended an arrangement people in the region knew. For callers the key point is simple: always dial all ten digits, the area code plus the seven digit number, even for a call across the street.
How a 206 Number Is Written
A full American number has ten digits. A Seattle number looks like this when written in plain groups: 206 555 0123. The first three digits are the area code, the next three are the exchange and the last four are the line.
Inside the United States you dial 1 and then all ten digits for a long distance call, or just the ten digits for a local one. From India you dial 00 or press plus, then the country code 1, then the ten digits. So the example becomes +1 206 555 0123.
Calling Seattle From India
Seattle has a large Indian community, many of them working in software, health care and research, so calls between India and the 206 area code are common. A few practical points:
- Time difference. Seattle is on Pacific Time. Since US daylight saving ended on 1 November 2026, Seattle is thirteen and a half hours behind India. From March, when clocks move forward, the gap becomes twelve and a half hours. Evening in India is early morning in Seattle.
- Cost. Ordinary international calls from Indian mobile plans can be expensive. Many families use internet calling apps instead, which only need data on both sides.
- Phone choice. Internet calling needs a smartphone. Our guide to choosing between smartphones and feature phones can help older relatives decide.
Getting a 206 Number Today
People moving to Seattle often ask whether they can still get a 206 number. The answer is yes in many cases, but it is no longer guaranteed. When a carrier issues a new line it draws from the blocks of numbers it holds, and some of those blocks now start with 564. Some residents ask the shop for a 206 number because the code feels local, and carriers will help if they have spare 206 numbers in stock. Businesses that want a familiar code sometimes buy numbers through their telephone provider rather than accept the first one offered. Either code reaches the same phones at the same local rates.
Unknown Calls From a 206 Number
Not every call that shows +1 206 is genuine. Caller ID can be faked, a trick called spoofing, so a scammer anywhere in the world can make a call appear to come from Seattle.
Common patterns include:
- A single ring that stops, hoping you will call back at a high international rate
- A caller claiming to be from a bank, a courier, an immigration office or a technology company
- A message saying a relative abroad is in trouble and needs money urgently
The safe response is the same for any number. Do not call back numbers you do not recognise. Do not share one time passwords, bank details or Aadhaar numbers over the phone. If a call claims to be from a relative, hang up and call them on the number you already have. Caller ID apps can flag many known scam numbers, as we explained in our article on Truecaller’s spam folders. In India suspicious calls can be reported on the Chakshu facility of the Sanchar Saathi portal run by the Department of Telecommunications.
How Area Codes Fit the Global System
The 206 code sits inside country code 1, which the United States shares with Canada and several Caribbean nations. Country codes themselves are assigned by the International Telecommunication Union, the United Nations agency for telecoms that is marked each year on World Telecommunication Day. India’s country code is 91, and within India there are STD codes such as 22 for Mumbai and 11 for Delhi that work in a similar way to American area codes.
Emergency calls in Seattle use 911, and the national mental health crisis line is 988, just as in the rest of the United States.
Toll free numbers in the United States start with codes such as 800 or 888 rather than a city code.
Mobile numbers in the United States keep their area code when the owner moves, so a 206 caller may live elsewhere.
Businesses in Seattle often print the full ten digit number on signs, since local calls need the code too.
Text messages from a 206 number follow the same rules as calls: do not click links from senders you do not know.
