The rollout of 564 does not strip away anyone's 206 number. The Washington Utilities and Transportation Commission structured the rollout so that residential and commercial subscribers retain their active lines. There is no automated reassignment, no mandatory trade-in, and no phase-out deadline for existing numbers.

The friction occurs during account modifications. When a business opens an additional branch in Ballard or adds virtual lines to an existing PBX system, telecom carriers pull from the active pool. In many central wire centers, that available pool consists primarily of 564 assignments. Retaining 206 for a newly established connection often requires buying pre-owned numbers from brokerages or paying carriers for secondary warehousing. The underlying service, whether residential fiber, corporate SIP trunks, or wireless carriers, operates identically across both codes.
