I called my doctor to schedule an appointment. They prompted me for who I wanted to see, and my date of birth, and that was it.

A date is easier to say (in many cases) and understand than a name; once they have a date, they can easily narrow the search space with another piece of relatively uninteresting (but uniquely identifying, as a pair) information; in my case, it was a unique birthday, so they didn’t need any additional information, beyond confirming it was me with my first name.
