To become a registered vendor with the Iowa DOT's Purchasing Section, both a Vendor Registration Form and a Federal Identification W-9 form must be completed. Begin the registration process by selecting the Vendor Registration Form below. Provide company name and the types of products or services available. A W-9 form must also be completed.
Vendor Registration Form: Select the category heading. Vendors will be added to a bidders list for the selected categories in the form to be considered for future opportunities to sell to the state.
W-9 Form: A Federal Employer Identification Number (FEIN) is required to register. A Social Security number must be provided if a FEIN number is not available according to the instructions included in the form. This form must be signed and returned by email, or by fax or standard mail.
Both forms can be submitted by:
Iowa Department of Transportation
800 Lincoln Way
Ames, Iowa 50010
Note: Vendors are responsible to notify the Iowa DOT Purchasing Section of any changes to company information.
