Prince William County - Vendor Registration/Login
The Prince William County Purchasing Regulations require that all firms register with the County prior to receiving a contract award. An approved vendor may receive notice of solicitations that fall within the selected capabilities.
Due to legal and security issues, each vendor must complete his/her own online registration at our secure website. Each vendor will create an User ID and Password and make any future changes to their information in our database.
If you have any questions/problems, please contact the Prince William County Purchasing Office at (703)-792-6770.
The Public School System and Service Authority each have their own independent Purchasing Departments. Specific information can be obtained by contacting the following:
