SCW are you looking for a paid or free source for global postcodes? –  Mapperz Apr 12 '11 at 19:07
    
A preference for free, but both are fine. –  scw Apr 12 '11 at 19:10

I asked a question recently, trying to achieve the opposite (had city, country wanted lat/long). I used this free database. It won't give you postcodes (so it's not really an answer), but it does give you city and country, if that is useful.
