Overview of Italy's +39 35 Mobile Prefix
The Italian national dialing plan, governed by the Autorità per le Garanzie nelle Comunicazioni (AGCOM) and following ITU-T E.164 recommendations, assigns non-geographic numbering ranges to mobile services. The prefix 35, when dialed as +39 35 from abroad or 035 domestically, is a mobile network prefix. It is important to note that the leading '0' is part of the national significant number (NSN) and is not a trunk prefix as in some countries; it is always dialed within Italy. This prefix is not tied to a specific geographic region, but is allocated to mobile network operators (MNOs) and mobile virtual network operators (MVNOs) operating on national networks.
Dialing Format and Number Structure
Italian mobile numbers, including those starting with 35, consist of 10 or 11 digits after the country code, depending on the operator and the specific number block. The format is: +39 35 XXXXXXX (where X represents the subscriber number). For example, a complete international dialing sequence would be +39 351 234 5678. When calling from a landline or mobile within Italy, you must dial the full national number including the leading zero: 0351 234 5678. The prefix 35 is used by several operators, including Iliad and other MVNOs, and numbers are portable across networks, meaning the original operator may not be the current provider.
Technical and Routing Considerations
Mobile numbers in Italy are non-geographic, meaning they are not associated with a fixed location. This allows users to keep their number when moving across the country. For international callers, the routing is handled by the Italian signaling network, which uses the prefix to identify the mobile network and route the call accordingly. SMS and MMS messages to +39 35 numbers are also routed via the mobile network. When dialing from abroad, the international access code (e.g., 00 from most European countries, or 011 from North America) is used, followed by Italy's country code 39, then the full national number without any additional trunk prefix. For example, from the US, you would dial 011 39 351 234 5678.
Number Portability and Cost Implications
Number portability is mandatory in Italy, allowing subscribers to switch operators while retaining their number. Therefore, a number starting with 35 may be serviced by any operator, and the original prefix does not determine the current provider. This affects routing and billing, as the network must query the number portability database to determine the correct destination. For callers, the cost of calling a 35 number is typically the same as calling any other Italian mobile number, but it is advisable to check with your service provider for international rates. For businesses, using a 35 number can be a strategic choice for mobile marketing campaigns, as it is recognized as a mobile service, but it is not a toll-free or premium rate number.
