technically, there is an upper limit of digits. Therefore Vienna, Austria,
has a national prefix (0222) and an international prefix (+43-1).
I fear that about every European country has its own convention of grouping
the digits. Here in Germany, it is even more complicated:
- There is the international prefix for Germany (+49)
- Phone numbers are nearly exclusively shown with the local prefix,
which always starts with the digit 0. This local prefix can have
anything between 3 and 5 digits, is put in brackets and grouped
in pairs as below.
- Finally you have the local numbers that can be anything from 3 to
8 digits, followed by any private exchange number and are grouped
in pairs from the back. Within a local calling area there might
even be numbers with different digit counts. If there is a private
exchange, the phone book shows -0 or so for the manual exchange.
On my letter head my phone number is (09 11) 40 39 03. Internationally I use
+49-911-403903 (this is what my footer should show :-).
If you wish to call the City of Frankfurt with no extension number, you find
(0 69) 2 12-01. The City of Frankfurt library has the Fax number (0 69)
2 12-3 79 49.
OK, let's face it: The phone number format is something you have to localize
- like many other things. E.g. in the US a car goes some miles per gallon,
over here it consumes some liters per 100 km.
