Understanding the 206/564 Overlay System

Seattle's telecommunications landscape changed significantly on June 10, 2025, with the implementation of the 564 area code overlay. This modern solution addresses number scarcity while preserving the iconic 206 designation.

How the Overlay Works:

Unlike traditional area code "splits" that divide regions geographically, an overlay serves the same territory with multiple area codes. This means:

• Same Geographic Coverage – Both 206 and 564 cover identical Seattle-area territories
• No Address Changes – Your location determines coverage, not your area code
• Equal Status – Neither area code is "better" or more prestigious than the other
• Seamless Integration – All local services work identically regardless of your area code

Practical Implications for Users:

Benefits of the Overlay Approach:

1. Preserves Local Identity – Historic 206 numbers maintain their significance
2. Eliminates Disruption – No forced number changes or service interruptions
3. Supports Growth – Ensures adequate numbering resources for Seattle's expansion
4. Cost-Effective – Avoids expensive geographic restructuring

Timeline and Implementation:

The overlay became fully operational on June 10, 2025, following an 18-month planning period that included public input and carrier coordination. The Washington Utilities and Transportation Commission approved the overlay expansion on June 15, 2023, responding to NANPA's October 2022 forecast that projected 206 exhaustion by Q4 2025.
