Telephone numbers in Italy

Country Code : +39
International Call Prefix: 00

Telephone numbers in Italy changed to a closed telephone numbering plan in 1998. The plan which had originally been advertised in early 1998 was to merge the trunk code '0' into subscribers' landline numbers effective June 19, 1998, and then to replace that leading '0' with a '4' starting from December 29, 2000. As a result of this change, all landline numbers would begin with a '4', and mobile phone numbers with a '3'. Other initial digits had been reserved for different special purposes. It was later decided that landline numbers should still begin with a '0', unlike in the closed numbering plans of many other countries. E.g. a land line number in Rome:

 06 xxxx xxxx (within Rome - after 1999)
 06 xxxx xxxx (within Italy)
 +39 06 xxxx xxxx (outside Italy - after 1998)

Calls to mobile phone numbers within Italy were also affected, deleting the previously used trunk code '0'. International calls to Italian mobile phone numbers were not affected. E.g. for former Omnitel, now Vodafone provider in Italy:

 0347 xxx xxxx (within Italy - before 1999)
 347 xxx xxxx (within Italy - after 1999)
 +39 347 xxx xxxx (outside Italy - both before and after 1999)

Landline numbers (area code+exchange+number) are generally 9 or 10 digits long, although they can be as little as 6 or as many as 11 digits. Mobile numbers are always 10 digits long, with the only exception of very old TIM numbers, which are 9 digits long (though those are now extremely rare).

[ Mobile Telephones

Mobile phone number in Italy: without a zero, started with a 3.

 3xx xxx xxxx (within Italy and San Marino)
 +39 3xx xxx xxxx (from the rest of the world)

[ San Marino

Until 1996, San Marino was part of the Italian numbering plan, using the Italian area code 0549 but in that year it adopted its own country code 378. However, instead of using international dialing codes, dialing arrangements between San Marino and Italy continued as before. In 1998, San Marino incorporated the 0549 area code into its subscribers' numbers, following the Italian format:

 0549 xxx xxx (San Marino from Italy)
 +378 0549 xxx xxx (San Marino from rest of the world)
 +39 0549 xxx xxx (San Marino via Italy)

[ Vatican City

Similarly, Vatican City is assigned country code 379. However, Vatican City is still reached via the Italian numbering plan. Telephone numbers in the Vatican City are similar to telephone numbers in Rome, with "698" following the "06" for Rome.

 06 698x xxxx (Vatican City from Italy)
 +39 06 698x xxxx (Vatican City from rest of the world)

It is to be noted that this numbering plan doesn't strictly follow the boundaries of the provinces and city areas in order to solve in a simple way some technical constraints. So, for example, the geographical province of Avellino has two main prefixes (0825 and 0827) but also some common land with other prefixes like 0824 for San Martino Valle Caudina and 081 as for Baiano.
