Should I put my social for Uber?

[Opus 17]

As a self-employed person, you can use your SSN as your tax number for your small business.

You have the option of getting a federal tax number to use instead.  Its free, and it saves you having to give your personal SSN to people you do business with, but it's not required unless you pay employees.
