How to call Washington from abroad
Every Washington phone number is part of the +1 North American calling zone. To reach one from outside the United States, dial three parts in order:
- 1. Your exit code, then +1 — the US country code.
- 2. The three-digit area code — for example 206 for the Seattle area.
- 3. The seven-digit local number.
Example, full international format:
+1 (206) 555-0100
With Phonecall you skip the exit codes entirely. Enter the number in international format and we connect the call from your browser, billed by the second from $0.03/min, with no SIM, no app, and no monthly fee.
Why Washington has multiple area codes
Western Washington uses the 564 overlay, requiring ten-digit dialing.
When a region runs low on available numbers, the phone system adds capacity in one of two ways. A split divides the old region geographically and gives part of it a brand-new area code. An overlay keeps the existing code and layers a second one on top of the same area, which is why a single city can have several area codes and why ten-digit dialing becomes the norm. Either way, the number you dial always stays the same length: +1, the area code, then seven digits.
