W-9 Form

When a department or school is selling a good or service to another company, the company may ask for the Northwestern University W-9 form and direct billing information so that NU can be added to their system. 

Please forward the request to Accounting Services at accounting@northwestern.edu or at ext. 1-5337.  In your request, please include:

  • Vendor Name
  • Name of the person who requested the certificate
  • Vendor e-mail address or fax number
  • Your name and contact information

Accounting Services will send the W-9 form directly to the vendor and e-mail confirm once it has been sent.
