IDNR Procurement

All vendors wishing to do business with any agency, board, or commission of the State of Illinois must register for an IDHR Eligibility Bidder Number through IDHR by filing an Employer Report Form (PC-1) with the IDHR Public Contracts unit prior to pursuing a state contract. The IDHR Eligibility Number demonstrates to the contracting agency proof of registration with IDHR.

In addition, Public Act 95-971 contains Board of Elections registration requirements regarding bids and proposals submitted by vendors. Below is a link to the Business Entity Registration for Procurement (BEREP).
