W-9 Requirements

The University is required to have an IRS form W-9 (Request for Taxpayer Identification) or W-8BEN (international vendors/individuals) or an acceptable substitute form on file for each vendor receiving payments from the University.   The data on the form contains the employer FEIN or, in the case of a sole proprietorship, the Social Security number of the vendor.   This number is used as the vendor identification number in all University-related transactions.  Please note that sole proprietors are assigned a UIN to conform to University policy.

The University uses the Substitute IRS Form W-9 or W-8BEN (international vendors/ individuals) that must be on file prior to invoice receipt from a vendor.
