I used to work for a university in Australia, our solution to mononymous students was to put their single name in both first name and surname fields. So if your name was just Mayawati, we'd put you down as Mayawati Mayawati.

Some US bureaucrats seem to like FNU (First Name Unknown) or LNU (Last Name Unknown). So one encounters mononymous Americans whose first name is Fnu or last name is Lnu. A while back I had a coworker whose surname was Fnu – I believe her legal paperwork had Fnu as her first name, but she got IT to swap her firstname and lastname in our corporate systems, because she didn't want people addressing her as Fnu.
