German Non-Geographical Numbers

Please correct me if I'm wrong, but according to wikipedia, calls to 0180 numbers cost more than to regular land lines, is there any other ranges that I should be aware of as well, other than the 090x premium rate numbers?

The reason I ask is e164.org has a Non-Geographical feature which can list tel: URIs against more expensive numbers so you get your calls cheaper.

So far we have Australia, France, Spain and the UK listed, although I'll try and get time to add the information for German numbers tomorrow.

Sorry for the delay, got caught up doing other things, however I've made the changes necessary to add 0180x or 090x numbers to the system and then using enum lookups you can get a cheaper alternative number to call if one exists in the system.

I don't know what mobile charges are like in Germany, however we have a wap interface for this search available as well:
