In the US, is it possible for the same 9 digits to exist as a valid SSN, and also as a valid EIN?

For example, Person One is 123-45-6789, and Business Two, Inc is 12-3456789.

  • Yes, it happens. I have no proof to show you though.

Apparently, it can happen.

On Reddit’s r/personalfinance subreddit, a user posted their story about this happening to them:

My SSN has the same integers as someone's EIN

A couple of people in the comments also claimed to have discovered this firsthand as well.
