Vendor Registration ProcessTo 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 listed below. Tell us about your company and the products or services you provide. The W-9 form must also be completed by clicking on the link below. (Please see specific instructions listed below.)
Select the category headings in which you wish to receive Bid and/or Request for Proposal (RFP) notifications by checking the appropriate lines and enter them on Line 10 of the vendor registration form. This form may be filled out online and saved in your files before attaching to an email to DOT.email@example.com.
W-9 Form: You will need your company's Federal Employer Identification Number (FEIN) in order to register with us. If your company does not have an FEIN, you must provide the owner's Social Security number according to the instructions included in the form. A signature is required for this form. The completed form may be faxed to the Iowa DOT's purchasing section at 515-239-1538. The W-9 form must be completed before the vendor registration form can be processed.
You may also download, complete, and mail these forms to:
