Geospatial Technology Services

The Geospatial Technology Services (GTS) Office for Prince William County is responsible for assigning and maintaining addresses, including suites, apartments, and buildings, in Prince William County (with the exception of the City of Manassas Park and the City of Manassas). PWC GTS retains limited information in the Towns of Dumfries, Haymarket, Occoquan and Quantico. 

An address assigned by the GTS Office is the official address. Self-addressing is not accepted in Prince William County. Any spaces that are self-addressed are subject to being reassigned by the GTS Office at the expense of the owner and/or tenants impacted.

Most new addresses are assigned as development occurs by the GTS Office during site plan review prior to the final approved plan or during the address validation portion of the permitting process. 

If your project does not require you to go through site plan review or address validation, we encourage you to contact our office at [email protected] for the official address assignment prior to finalizing any legal documentation or recorded documents. 

It is important that all occupied buildings and spaces use the official address assigned by the PWC GTS Office and post your address clearly and visibly in compliance with the Code of Ordinances. 

More information can be found in the County Code of Ordinances, Section 24, Article II.
