Connecting Hillsboro Address Project

Hillsboro residents and businesses will enjoy better service delivery and a stronger community identity through the Connecting Hillsboro Address Project. Some residents' and businesses' addresses have changed as the program has replaced County road numbers and addresses with City street numbers and addresses.

Until recently, locations in the City have used City of Hillsboro and Washington County addressing systems, plus two non-Hillsboro ZIP codes. The Project establishes a consistent addressing system by reconciling the City of Hillsboro and Washington County address grids.

Address Change Notification Letters

The City is implementing the project in phases. Using the phase number from your notification letter, check below to confirm the date when your transition period will end. Your new address must be in full use by the end of the transition period.

If you don't know your phase number, please call the City of Hillsboro Planning Department at 503-681-6153 or view the Connecting Hillsboro Address Implementation Schedule
