I have a one-word name. It's my "legal," wallet-name. The only corporation/government/monoliths that address me with that one name is the department of licensing (my drivers license) and the State Department (my passport), both of which just show my one name.
I have to just make things up for one or the other field (first, last). Usually I go with my initial as my first name, and my name as my last name. Or my one name in both fields. I once signed up to some web service that I didn't care about with a last name of IHaveNoLastNameAndThisFieldIsTotallyMadeUp.
