Area Code Breakdown & District Mapping
425 – Puget Sound Eastside Code
Area code 425 was created in 1997 when it split from 206, serving the Eastside and north Puget Sound suburbs including Bellevue, Redmond, Kirkland, and Everett. It is Bellevue’s primary code within King County.
564 – Washington Statewide Overlay
Area code 564 is Washington’s statewide overlay, introduced in 2017 to add numbering capacity across the entire state. In Bellevue it overlays 425, so new lines may be issued a 564 number that is fully local to existing 425 numbers.
Neighborhoods & Local Coverage
Bellevue’s 425 code covers a city anchored by a dense, fast-growing Downtown, where the luxury Bellevue Collection shopping district and a cluster of high-rise offices and condos have made it a rival to Seattle across Lake Washington. The Bel-Red corridor to the northeast is a booming tech and light-rail development zone.
Beyond downtown, the same codes reach the diverse Crossroads district, the Factoria and Eastgate areas to the south, and the leafy residential neighborhoods of Somerset, Newport, and Wilburton. The 425 and 564 codes also tie Bellevue to its Eastside neighbors like Redmond, Kirkland, and Issaquah.
Local Dialing Rules & the Statewide 564 Overlay
Bellevue and all of Washington have required 10-digit dialing for years — always dial the area code plus the 7-digit number. The Eastside uses 425, while the statewide 564 overlay adds new numbers across the same territory. Across the lake, Seattle uses 206.
Washington’s 564 code is unusual: rather than overlaying a single region, it is a statewide overlay introduced in 2017 to add capacity across every existing Washington area code. That means a 564 number can be based anywhere in the state, and 10-digit dialing is mandatory everywhere in Washington.
To call Bellevue from outside the United States, dial your country’s exit code, then the U.S. country code +1, followed by the 10-digit number (for example, +1 425 XXX-XXXX). From inside the U.S. and Canada, simply dial 1 before the 10-digit number for long-distance calls.
Major ZIP Codes Covered
The 425 service area spans many of Bellevue’s core ZIP codes, including 98004, 98005, 98006, 98007, and 98008.
Spam & Scam Call Warnings in Bellevue
Bellevue residents report neighbor-spoofing robocalls faking a local 425 prefix, plus tech-support and fake-investment scams targeting the area’s affluent, tech-heavy population. Fake utility-shutoff and delivery scams are also common.
| Scam Type | What to Watch For |
|---|---|
| Neighbor Spoofing | Calls that mimic a local 425 prefix to look familiar. |
| Utility / Toll Scams | Threats to shut off power or demand toll payment via gift cards. |
| IRS / Government | Robocalls claiming legal action — agencies never call to demand instant payment. |
Red flag: Any caller who pressures you to pay immediately with gift cards, wire transfers, or cryptocurrency is almost certainly running a scam. Hang up and verify through an official number.
