Attachment D - W-9 doc.docx

This is a W-9 documentation attachment issued by the Colorado School for the Deaf and the Blind (CSDB) as part of their Request for Documented Quotation (DQ) process. The W-9 form is a mandatory requirement for all vendors seeking payment for goods and/or services provided to CSDB. Vendors must complete and submit the W-9 form if they are new to CSDB and have never received payment from the organization or any other state agency, are updating existing vendor information, or have not received payment from CSDB or another state agency within the preceding 18 months. The form must be completed with precise information that matches the vendor's social security card or business registration documentation filed with the Colorado Secretary of State to ensure accurate payment processing and prevent delays.

The accuracy and completeness of W-9 information is critical to CSDB's vendor payment workflow. Vendors are required to provide information exactly as it appears on official documentation, as discrepancies between the W-9 submission and records on file may result in payment delays. Instructions for properly completing the W-9 form are provided within the vendor packet distributed with the DQ solicitation.
