Obtaining a New York State Vendor Identification Number
If your company is not currently registered with the New York State Vendor File administered by the Office of the State Comptroller (OSC), please visit: (http://www.osc.state.ny.us/vendor_management/) for instructions on how to register.

Complete the OSC Substitute W-9 form (http://www.osc.state.ny.us/vendors/forms/ac3237_fe.pdf) and submit the form to OGS with your bid.

If your company is required to submit a Vendor Responsibility Questionnaire, OGS recommends completing the questionnaire online using the New York State VendRep System. In this case, your company must be assigned a Vendor ID to enroll in the VendRep System. To request assignment of a Vendor ID to access the VendRep System in advance of submitting your bid, contact the Office of the State Comptroller's Help Desk at 866-370-4672 or 518-408-4672 or by email at ciohelpdesk@osc.state.ny.us

Once the process is initiated, registrants will receive an e-mail identifying their unique ten-digit Vendor ID and instructions on how to enroll in the online Vendor Self-Service application.
