Request for SSN of AU
I keep getting letters and emails about providing the SSN for an AU on a business card. I have not provided it since I can not see any advantage to giving it to them. I do not want the AU to be listed on any credit report that other banks would see or in AMEX's decisions to approve the AU for any future cards as the primary applicant.
Are there any advantages/disadvantages to providing/not providing the SSN?
