How to read a number

+393471234567

+39Country code: Italy.
347Mobile range: Italy has no trunk prefix — dial the number exactly as written, with no leading 0. Numbers starting with 3 are mobile.
1234567Remaining 7 digits: Subscriber number. AGCOM allocates numbers in blocks of 100, and numbers can be ported, so 3xx only tells you it’s a mobile — not which operator.

Dialled domestically as 347 123 4567 — usually 9 or 10 digits, with no leading 0.

Number ranges & quality

Range	Type	Notes
`3xx (e.g. 3xx-xxxxxxx, 9–10 digits)`	Mobile carrier	Italian mobile numbers start with 3; MVNOs use the same range and numbers can be ported, so the prefix doesn’t identify the operator.

Virtual-number riskLow

ID requiredRegistration before activation is mandatory (D.Lgs. 259/2003 art. 98-undetricies, eSIM included); foreigners can use a passport, and codice fiscale requirements vary by operator.

Physical SIMs can sign up without issues. WhatsApp and Telegram are widely used in Italy.

Carriers & prefixes

Mobile prefixes by carrier.

Number portability applies — a prefix only shows the original carrier. AGCOM: porting is free and normally completed within 2 business days. Since 2022, to curb SIM-swap fraud, only the number’s own holder can request it, with identity confirmed by SMS code.

SIM cards & keeping a number

Italian SIMs (prepaid and eSIM included) must be registered before activation: art. 98-undetricies of the Electronic Communications Code (D.Lgs. 259/2003) requires operators to check ID at delivery, record the document type and number and keep a copy. Foreigners can use a passport; codice fiscale (tax code) requirements vary by operator — TIM can generate a provisional one for tourists from a passport.

Keeping a prepaid number is easy: use or top up roughly once a year. Iliad officially says 12 months; TIM’s service charter says 12 + 1 months. After deactivation there is still a window to reclaim the number for free.
