Subcontractors must register annually with IDOT in order to be approved for and participate on IDOT projects. Prequalified contractors are automatically included on the list of registered firms and are NOT required to register. Additionally, material suppliers, trucking companies, and companies that provide professional services (i.e. consultants) are NOT included in the definition of subcontractor and are not required to register.

HOW DO I GET REGISTERED?
Subcontractors can register electronically by submitting the Subcontractor Registration Form.
Approximately one month prior to expiration, a notice to renew registration and instructions will be sent via email.

If a revision is required at any time do not register again. Revisions can be made by submitting a
