Vendor Information

Vendor Information for Financial Transactions

To be paid or have any other financial transaction with the City, such as receiving a Purchase Order or Contract, each vendor must have a vendor number. For the City to assign a vendor number, we must have an updated W-9 Form, your current address, telephone, and e-mail information.

The City must have your most current contact information in the financial information system database. Otherwise, you might not receive purchase orders, contracts, payment checks, or other official business correspondence from the City. It is your responsibility as a vendor to ensure that the City has your up-to-date contact and business information.

This information should be provided on the Vendor Application Form. The Vendor Application Form can be submitted electronically by clicking the "Submit" button or by simply pressing the "Enter" key. Your information will be transmitted to the City over a secure SSL connection. A blank W-9 Form can be found:

Form W-9

The completed, signed, and dated Form W-9 can be scanned and e-mailed to: vendors@cityofrochester.gov or mailed to the City of Rochester, Bureau of Purchasing, Attn: W-9 Processing, City Hall, Rm. 105-A, 30 Church St., Rochester, NY, 14614. Once your application and/or W-9 has been accepted, the City will e-mail a confirmation verifying the information has been entered into the finance system. If the City has issued a new vendor number to your company, this number will be included in your confirmation e-mail.
