Hi Jennifer,
Thank you for reaching out to the Microsoft Advertising Learn Q&A Platform! My name is Jefferson, and I will be assisting you with this query.
I understand that you're in need of a copy of Microsoft’s W-9 form for your company. I've sent you a private message with the W9 form.
If you have any more questions or need further assistance, feel free to ask!
Thank you so much.
