Important Announcement: Change to New Messaging System

Prince William County will start using a more robust alert notification system starting March 1, 2019. If you would like to continue to receive County Address Changes from Prince William County government, you must sign up for a new account and register your devices at by February 28, 2019. The old system will not work after February 28, 2019.  You can find County Address Changes under the Planning & Development Category.   The new system is much more dynamic and allows you to customize how you prefer to receive information by text, email, voice and/or mobile app.  The system will first send a message to what you designate as your primary means of notification. If it doesn't reach you that way, it will try another method. The system also allows you to create a "do not disturb" timeframe, so that you only receive notifications during the times you designate. 


Who is the Addressing Authority in Prince William County?

The GIS (Geographic Information Systems) Office for Prince William County is responsible for assigning and maintaining addresses for every parcel and premise in Prince William County (with the exception of Manassas Park and the City of Manassas). PWC GIS retains limited information in the Towns of Dumfries, Haymarket, Occoquan and Quantico.

Per the County Code of Ordinances, Article II, an address assigned by the GIS Office is the official address of record. This article also establishes that the GIS Office interprets, administers and enforces the addressing of Prince William County, including issuance of violations to ensure compliance to the Code.

Prince William County has three (3) different types of addresses: 

  • Parcel addresses are assigned to a single piece of land. 
  • Premise addresses are assigned to buildings and/or units that are located on a parcel of land. 
  • Unoccupied Structure addresses are assigned to freestanding or attached structures that are not meant to be occupied as residential or commercial space but require permits or a phone. Examples are retaining walls, cell towers, signs, meters and many more.

 In cases where the parcel of land contains a single structure that is owner-occupied, the parcel address and premise address are the same. In cases where many structures are located on the same parcel (such as apartment complexes or business parks), the premise address will be different than the parcel address.

Buildings with multiple units will have one address for the main entrance with a unit, apartment or suite number to identify each separate unit. Houses or single tenant buildings have one address for the entire structure.
