Sometimes there are obscure codes on bus stops (eg in Oxford), so that humans can text them to a Real Time Passenger Info service (called OxonTime here). Eg the ref tag on this node:
http://www.openstreetmap.org/browse/node/533877725 For which you can get a departures list: http://www.oxontime.com/pip/stop_simulator.asp?naptan=69345648 I make that three different stop ids, plus some other stuff that could probably be combined to make one. If you haven't got unique ids yet, then it's quite likely that someone will introduce them soon. You know, you wait ages for a unique id then three come along at once...
