What credit cards allow you to add an Authorized User WITHOUT requiring their social security number?
Both personal and small business credit cards would be helpful. Thanks!
I know through personal experience that American Express DOES require a SS# when adding additional cardholders (at least for personal cards), and that Advanta does NOT require a SS# when adding additional cardholders.
Personal experience with additional issuers would be helpful.
Please provide specific credit card issuers. Thanks!

I think all credit cards allow you. I know Bank of America does for sure.
I don’t know about business, but I listed my daughter as an authorized user without giving her social security number on a personal card
As far as I know, most credit cards allow you to add an authorized user without a social security number.
