Subcontractor/Supplier/Subconsultant Services
Resources and Information
To participate on any CDB project as a subcontractor, supplier or in any capacity you must have a CDB REGISTRATION #.
If you are currently or have ever been prequalified with CDB your firm has been assigned a registration number, therefore you do not need to register with CDB
If you are a subcontractor, material supplier, or a consultant (who is not required to be prequalified), then you must register.
Note: Prequalified firms who will perform at times as a subcontractor do not need to register.
To inquire about an existing registration # send an email to:
CDB.SubContractReg@illinois.gov
To apply for a new # use the attached link which will take you to Vendor Registration.
