For the second piece of identification I would need when applying for a driver’s license, I planned to dummy up a W-2 form, which would require me to supply the Employer Identification Number (EIN) of the W-2 issuer. It’s a simple matter to find that number for almost any company you pick at random. I called Accounts Receivable at Microsoft and asked for its EIN "so we can submit our payment." The lady on the other end of the line gave it to me without even asking what company I was calling from.
