The City offers a Vendor Self-Serve module to help vendors do business with the City. In order to become a vendor, or to create a User ID if you are an existing vendor, please use the Vendor Self-Serve.

Existing vendors will need their vendor number and their Federal Tax ID number in order to register for online access. Please do not register as a new vendor if you are already registered as a vendor with the City.

Sign up to be notified about bidding opportunities.

Here are links to the IRS W-9 form and the IRS W-8 form series.

Please contact the Procurement Division at (520) 458-3315 with any questions. Thank you for your interest!
