Having the additional context of knowing the country means you have a better chance of deciphering the data to get some information. Jan,

I do not see the problem, when you know which country number belongs to and in case you do not know which country it belongs to i find it impossible To check if the number is right i find the best way to count digits in international format. As you mentioned Hungary and its open dialing plan. You can come accross numbers in clasifieds in three format 062xxx, +362xxx or 2xxx. Which is the most confusing I have ever come across :-) Thats very interesting question.
