How to call Italy from the US (+39 dialing guide)

Formula

From the US: 011 (or +) → 39 → Italian NSN (keep geographic leading 0; mobiles as 3XX…).

X characters are placeholders, not a private callable number. Save +39 in contacts; use 011 only for all-digit US access.

Dial it step by step

1. 1

   Exit the US network. On a mobile or modern contact book, start with +. On a US landline, PBX, or digit-only service, dial 011.

2. 2

   Add the Italy country calling code: 39.

3. 3

   Add the NSN. Keep the leading 0 on geographic numbers such as 06. For mobiles, use the digits beginning with 3 and do not add a 0.

Mobile and landline rules

• Geographic landline: keep the 0 after +39.
• Mobile: use +39 followed by the digits beginning with 3; add no trunk 0.
• Italy is an explicit exception to the common drop-the-zero rule.

See the Italy calling-code reference and the international dialing format guide.

Worked examples

Domestic → portable international → digits-only from United States. All subscriber digits shown as X are placeholders.

Common mistakes on this route

• Removing the 0 from an Italian geographic number.
• Adding a leading 0 before an Italian mobile.
• Saving 011 in the contact instead of +39.

Time difference (practical)

Italy is typically about six hours ahead of US Eastern. DST schedules differ, so the gap can shift by an hour around transitions.

How the international format is built

Under ITU-T E.164, the international number is the country code plus national significant number, with a maximum of 15 digits. The + symbol and spacing are access/display notation rather than E.164 digits.
