|List of Italy dialing codes|
Telephone numbers in Italy are managed by the Autorità per le Garanzie nelle Comunicazioni (AGCOM), a national regulatory authority for the communication industry located in Rome.
Telephone numbers are defined by an open telephone numbering plan that assigns subscriber telephone numbers of six to eleven digits. In addition, other short codes are used for special services. The plan is organized by types of services,indicated by the first digit. Geographic landline numbers start with the digit 0, while mobile telephone numbers start with 3. Four types of emergency services use three-digit telephone numbers in the group 11X, including 112 for the Carabinieri. Other initial digits denote other services, such as toll-free numbers.
The dialing procedures for callers mandate that the full telephone number is always dialed, including the area code, which is called prefix (prefisso in Italian). Since 1998, the leading 0 of landline numbers has to be included also when calling in from abroad, in contrast with the practice in many other countries. (See Historical number formats below for an example.)
The country code for calling Italy from abroad is 39.For calling foreign destinations from Italy, the international call prefix is 00, as is standard in most European countries.
The regulations for Italian telephone numbers prescribe no fixed rules for grouping the digits for printing or display. Various grouping schemes are commonly used and a telephone number is likely to be written or pronounced differently by different people. Commonly used formatting or punctuation characters include the space character, the dot, full stop, and the hyphen.
The minimum length of telephone numbers is three digits and the maximum is twelve.
Landline numbers start with the digit 0 and are 6 to 11 digits long, although they are rarely shorter than 9. They are composed of a variable length prefix followed by a variable length subscriber number.
Prefixes are assigned on a geographical basis, starting from the north of the country; for example: Rome has prefix "06", Milan has "02", Naples has "081", and Turin has "011".
Mobile telephone numbers start with the digit 3 and are generally ten digits long. It is still possible, but rare, to find nine-digit numbers, which were the first to be assigned.
The group of the first three digits of a mobile telephone number (prefix) identifies the mobile network operator that assigned the number, but since 2002, mobile number portability is possible and thus any number can end up being managed by any carrier.
Some network operators allow the caller to insert additional digits for redirecting calls to voice mail. For example, dialing, "36 339 7550176" might connect to the voice mail service of the telephone number "881 7550176". The extra digits vary based on the network operator managing the service.
Emergency and service numbers start with the digit 1. Four emergency numbers are currently in use, but a process has been started to consolidate them with 112, previously assigned to the gendarmerie, already the unique emergency number in some areas.Calls to 112 are answered within seconds and in multiple languages.
The complete list of emergency numbers is:
Other service numbers are:
Special-rate numbers start with 8 and include toll-free numbers (called green numbers, numeri verdi in Italian, starting with "80..."), shared-rate numbers ("84...") and premium-rate services ("89...").
Numbers starting with 4 are used for network-specific phone services like voice mailbox and various information services; they can be free, non-premium or premium.
Included in this category are, among others:
The digit 5 has been reserved for VoIP numbers.
Finally 7 is used for internet services such as virtual fax numbers and dial up internet access ("70...").
Numbers starting with the digits 2, 6 and 9 are currently unassigned and reserved for future purposes.
In the past it was possible to omit the prefix when calling from a landline to another landline in the same area. The digit "0" was the trunk code and it had to be removed when calling from abroad.
This changed in 1998, with a transition period lasting from 19 June to 31 December. The new dialing procedures require dialing the full number for all calls. The main advantage is the availability of millions of previously reserved phone numbers.The change was widely advertised with a campaign named "Fissa il prefisso" ("Attach the prefix").
It was originally intended to replace the leading 0 with 4 for landlines. This was scheduled for implementation commencing 29 December 2000, but never happened. Instead, 4 was assigned to identify network services.
Example for calling the landline subscriber number xxxxxxxx in Rome:
Until 2001 a leading "0" was part of any mobile phone number, but it has been removed.
Example for calling the mobile phone number 3xxxxxxxxx:
Several other smaller changes occurred during the years: for example the prefix for toll free numbers changed from "167" to "800" in 1999.
The Italian municipality Campione d'Italia, an exclave within the Swiss canton of Ticino, uses the Swiss telephone network and is part of the Swiss numbering plan, with local numbers using the +41 91 numbering range, although some Italian numbers are in use by the municipal council, which use the same +39 031 numbering range as the town of Como.
The Italian enclave San Marino has its own country code 378, but landline numbers can be reached using the Italian country code as well: the prefix "0549" is assigned to San Marino. Dialing either "+378 xxxxxx" or "+39 0549 xxxxxx" will reach the same number. Mobile phone customers are sometimes assigned Italian phone numbers.
The country code 379 is assigned to Vatican City, but it is not used: telephone numbers in Vatican City are integrated into the Italian numbering plan. Vatican landline telephone numbers are in the form "+39 06 698xxxxx", "+39" being the country code for Italy and "06" the prefix for Rome.
A toll-free telephone number or freephone number is a telephone number that is billed for all arriving calls instead of incurring charges to the originating telephone subscriber. For the calling party, a call to a toll-free number from a landline is free of charge.
A telephone numbering plan is a type of numbering scheme used in telecommunication to assign telephone numbers to subscriber telephones or other telephony endpoints. Telephone numbers are the addresses of participants in a telephone network, reachable by a system of destination code routing. Telephone numbering plans are defined in each of administrative regions of the public switched telephone network (PSTN) and they are also present in private telephone networks. For public number systems, geographic location plays a role in the sequence of numbers assigned to each telephone subscriber.
The Australian telephone numbering plan describes the allocation of phone numbers in Australia. It has changed many times, the most recent major reorganisation by the Australian Communications and Media Authority taking place between 1994 and 1998.
Telephone numbers in Hong Kong are mostly eight-digit. Fixed land line numbers start with 2 or 3, mobile (cellular) phone numbers with 5, 6, 7 or 9, pager numbers with 7 and forwarding service with 8. Since the end of 1989, there have been no area codes within Hong Kong.
Numbers on the Irish telephone numbering plan are regulated and assigned to operators by ComReg.
Telephone numbers in Cyprus follow a closed telephone numbering plan which was adopted on 1 December 2001. As a result, for landline phone numbers the digit 2 followed by the old area code was affixed to the subscriber number and for mobile phones 9 was affixed to the phone number. The plan is also used in Akrotiri and Dhekelia.
The dialling plan for mobile networks and new landline operators is closed; all subscriber numbers must be dialled in full. For landline numbers starting with 02, the dialling plan used to be open; the trunk digit and area code could be omitted if the caller was in the same area code as the callee. However, starting May 3, 2008, all landline numbers must be dialled in full.
The Brazilian telephone numbering plan uses a two-digit area code plus eight-digit local phone numbers for landlines and nine digits for mobile lines. Public utility services use short phone numbers, always starting with 1.
The New Zealand telephone numbering plan describes the allocation of telephone numbers in New Zealand and the Pitcairn Islands.
Telephone numbers in Malaysia are regulated by the Malaysian Communications and Multimedia Commission (MCMC).

Lithuania uses an open telephone numbering plan with all phone numbers having nine digits, including the prefix "8", a 1-3 digit area code and 5-7 digit subscriber telephone number. The current plan was introduced in stages in 2001-2003, replacing Soviet-legacy area codes and altering some subscriber numbers.
Telephone numbers in Israel consist of an area code and a subscriber number. The dial plan type in Israel is closed, and "0" is the internal Trunk prefix in Israel. Israel's country calling code is +972.

Telephone numbers in Pakistan are ten digits long. Landline numbers and mobile numbers have different structures. Geographically fixed landline are prefixed by an area code which varies in length depending on the significance of the place. Mobile numbers are prefixed (03) followed by a code indicating the telephone operator.The international country code for Pakistan is '+92'.
The national conventions for writing telephone numbers vary by country. While international standards exist in the form of the International Telecommunication Union sector ITU-T issued recommendation E.123, national telephone numbering plans define the format and length of telephone numbers assigned to telephones.
The Gibraltar telephone numbering plan is the system used for assigning telephone numbers in the British Overseas Territory of Gibraltar. It is regulated by the Gibraltar Regulatory Authority (GRA), which holds responsibility for telecommunications. Gibraltar does not have the same code, +44 as the United Kingdom.
