This is a Substitute Form W-9 issued by the County of Greenville, South Carolina, designed to collect taxpayer identification information from vendors and contractors conducting business with the county. The form requires submission of legal business name, taxpayer identification number (either SSN or EIN/FIN), legal address, and entity tax classification. Vendors must specify the type of service or product being provided, selecting from categories including medical/veterinarian services, legal/attorney services, rental of real property, or products/services. The form also requires payment remittance information including a contact name, telephone number, fax number, and email address. The document explicitly states that the IRS Form W-9 will not be accepted as a substitute and that failure to provide the required information in a timely manner could prevent or delay payment.

The vendor must certify under penalties of perjury that the taxpayer identification number provided is correct, that they are not subject to backup withholding by the Internal Revenue Service, and that they are a U.S. citizen or other U.S. person. This form was revised in October 2022 and serves as a mandatory requirement for any entity seeking to contract with Greenville County. The form is directly associated with a procurement solicitation for geosynthetic materials (GCL, 60-mil HDPE, and geocomposite) for landfill base liner construction at the Twin Chimneys Landfill, with materials required for delivery and storage by October-November 2026. Qualified vendors must be approved geosynthetics installers or material manufacturers capable of procuring, storing, and delivering the specified materials within the required timeframe.
