Telephone mystery message box

I'm making a kind of scavenger hunt game (a bit like an alternative reality game, but for people I know), and I'd like a feature where someone has to call a phone number and enter a 4 (or so) digit code to hear a recorded message. I'd like to have this number be able to serve a few messages for a few different codes. I'd also like this to be a UK number if possible. I'm not sure how to Google for this; is anyone aware of a service like what I've described?
