The sales tax exempt number assigned to NC State from the Department of Revenue is 400021.
However, most suppliers will also issue an internal tax exempt number for cardholders to use once the tax exempt form has been provided to them.
A list of tax exempt numbers for a selection of company suppliers (Food Lion, Staples, Dollar General, Lowe’s Hardware, Home Depot, Office Depot/Office Max, Wal-Mart), and states’ exemptions for sales and use tax can be found on the University Controller’s Office, Sales and Use Tax website.
