Vatican telephone numbers are in the form of "+3906698xxxxx", "+39" being the country code for Italy and "06" the area code for Rome (the city surrounding Vatican City). Dialling the country code for calls within Vatican City or between Italy and Vatican City is not required, but the area code must always be dialed, as for any other call within Italy, since Italy is under a closed telephone dialing plan.
