Yes, but remember that the initial '0' is not really counted - that is just put on to tell the system that you are dialling an area or country code rather than a local number. Also, there are mobiles, fax machines, office numbers, computer networks, numbers for advertising etc etc, so it's not just for people. I personally use three numbers myself so it's not out of the way.
