Most properties in the City of Hillsboro have an address based on the City grid, which originates at 1st Avenue and Main Street in Downtown Hillsboro. However, some property addresses are based on the Washington County grid.

Back in 2000, Hillsboro community members voiced their desire for a uniform addressing system in the Hillsboro 2020 Vision & Action Plan, since updated as the Hillsboro 2035 Community Plan. The Plan calls for a Hillsboro-based address for every home and business within City boundaries. Additionally, emergency responders have cited potential confusion and delays caused by the mix of City-based and County-based street addresses.

First, you do not need to file a change of address form with the U.S. Postal Service (USPS) — the City notified USPS on the effective date of your address change.

However, you do need to call the Washington County Assessment & Taxation office at 503-846-8741 to update your mailing address. In addition, you'll want to notify anyone who sends you mail, just like when you move.

Here are a few examples:

• Oregon Department of Motor Vehicles
• Oregon Voter Registration
• Northwest Natural
• Portland General Electric
• Tualatin Valley Water District
• Frontier Communications

The updates may take some time, so please follow up with your service providers after a few months to make sure they have your new address.

The City of Hillsboro sends address updates to online map services, like Google Maps and Garmin, every quarter. Organizations that manage those map services implement the updates on their own schedules, so it may take several months for you to see a new address in an online map.

The City will support residents and businesses in several ways.

1. Both old and new addresses will be valid during a "transition period" of one year for residential addresses and two years for commercial and industrial addresses.
2. The City will install and maintain dual street signs — with both the old and new street names — during this transition period.
3. The City will send address-change notification letters to affected Hillsboro residents and businesses. The letters will serve as official documentation of the effective date of the change, which some utilities and services may require from account holders.

Start using your new address soon after the effective date, which is listed in your notification letter. We recommend using up any existing address labels, letterhead, business cards, etc., during the one- or two-year transition period, and ordering supplies with your new address.

Finally, if your house or building number changes, we recommend installing the new numbers shortly after you receive your notification letter.

If you have questions about using your new address, please call the City of Hillsboro Planning Department at 503-681-6153.

Property owners assign numbers to apartments and suites, with support and direction from the City. Your apartment or suite number will stay the same unless the property owner chooses to change it.

Apartment managers or homeowners' associations are responsible for maintaining street signs on private streets. Therefore, they would need to replace the existing signs with signs that show the new street name.

The City will install new street signs for private streets where they intersect with public streets (for example, when NW Overlook Drive intersects NW John Olsen Avenue, or when NW Venetian Drive intersects with NW Evergreen Parkway).

USPS recognizes both Beaverton and Hillsboro within the 97006 ZIP code. If you live within Hillsboro city limits, then Hillsboro is the preferred city to use in your mailing address. However, because of the way USPS coordinates mail delivery for the 97006 ZIP code, you may still receive mail that lists your new address with Beaverton as the city.

If you are having issues with receiving mail in the 97006 ZIP code, please contact the post office on NE Aloclek Drive at 503-614-9516.

Emergency responders have cited potential confusion and delays caused by the mix of City-based and County-based street addresses. The Connecting Hillsboro Address Project helps improve emergency response times by making addresses more consistent.

As of the effective date of the new address, 911 call takers will see your new address if you call from a landline in your home. If you use a VoIP service like Vonage, you will need to contact your service provider to update your address.

Both old and new residential addresses will be included on the 911 map for one year (two years for nonresidential addresses) after your new address becomes effective. However, use your new address when calling 911, and for consistency, adopt your new address as soon as it becomes effective.

Generally, north-south streets that are numbered, such as NW 215th Avenue, are changing to numbers that align with the distance from 1st Avenue in Downtown Hillsboro. East-west named streets, such as NW Evergreen Parkway, will retain their names; however, the streets' directionals may change (e.g., NW Evergreen Parkway may become NE Evergreen Parkway).

However, some address numbers will switch from a County address to a City of Hillsboro address. Also, in a few instances, streets will be renamed in anticipation of future road connections and/or realignments.

The City of Hillsboro’s population is projected to increase by 2035 to 116,000 residents, and employment is projected to grow to 103,000. Taking action now, rather than delaying, will help to ensure that the change affects as few residents and businesses as possible.
