I'm not aware of any surcharged numbers other than the well-known
(within the NANP, at least) 900 and 976 numbers.

Some of the Caribbean countries have caller pays mobile, and calls
to mobiles cost more. My VoIP carrier publishes the list of number
ranges it surcharges:

For the NANP countries that do this, it's generally a random set of prefixes
which I agree is pretty user hostile.
