Illinois Department of Transportation Subcontractor Registration
Federal law requires that the Department maintain a list of all contractors and subcontractors performing work on Department projects.
Subcontractors interested in participating on contracts will be required to register with the Department.
Prequalified contractors are automatically included in the list and are NOT required to register.
Material suppliers, trucking companies, and companies providing professional services (Consultants) are NOT included in this definition of subcontractor and are not required to register.
Subcontractors can register electronically by submitting the Subcontractor Registration Form.
The registration form requires minimal information and can be completed in minutes.
Confirmation, along with a registration number, will be received via e-mail in 1-2 days. Registration is valid for one year and will require renewal. Effective May 1, 2000, only registered subcontractors will be approved for Department projects.
Approximately one month prior to expiration, a notice to renew registration and instructions will be sent via email. If a Subcontractor does not have a valid email address, a notice will be sent via postal mail. Beginning June 1, 2005, Subcontractors will be able to renew their registration electronically by submitting the Subcontractor Renewal Form.
If a revision is required at any time do not register again. Revisions can be made by submitting a renewal online or by calling the Prequalification Section. Questions or comments may be addressed to the Prequalification Section, Bureau of Construction at (217) 782-3413.
