Central Annexation Tracking System

This annexation tracking site provides a convenient location where federal and state agencies, local governments, organizations, and members of the public can obtain information about annexations. State agencies that use this site include WSDOT Geographic Services, DOR Tax Payer Account Administration, and DOR Property Tax Division.

Materials are posted when they are received by OFM and updated as appropriate. They may not be accurate until an OFM File Number is assigned. See the certificate to view the current status of an annexation.
