How to Get a 425 Phone Number
There are three ways to get a phone number with the 425 area code, each suited to a different need:
- Buy from a premium-number specialist. Companies that hold curated inventories of specific area codes can sell you a 425 number directly, often with a one-time fee and ownership transferred to you (no recurring carrier fees). This is the option for picking a specific memorable number, or for getting an area code that most carriers won’t let you request. Contact us about a 425 number.
- Sign up with a VoIP carrier. Voice-over-IP services (such as Google Voice, OpenPhone, Grasshopper, and many others) can typically provision a 425 number on request, especially for active overlay codes. You won’t usually get to pick the specific number, but you’ll get a working line in the area code. This is the cheapest option for anyone who doesn’t need a particular number.
- Port an existing 425 number. If you already have a 425 phone number with another carrier, you can transfer it (port it) to a new service provider while keeping the number. This works for landlines, cell phones, and VoIP services, though landlines outside of Washington sometimes can’t accept inbound ports of 425 numbers due to 911 routing rules.

On April 27, 1997, area code 206 was split three ways. Area code 425 was assigned to Seattle’s Eastside and southern Snohomish County; area code 253 went to the Tacoma area; and 206 was retained for Seattle proper.
