How to Call Italy from the USA (2026 Guide): Country Code, Dialing Format, Costs, and Best Calling Methods

Communication between the United States and Italy remains one of the busiest transatlantic calling corridors in the world. Italy recorded about 185 million tourist arrivals in 2025, and the United States is home to over 16 million people of Italian ancestry, creating a constant need for affordable and reliable communication.

Although international communication is easier than ever, many callers still struggle with Italy's unique dialing system. Unlike most countries, Italy keeps the leading zero for landline numbers even when dialing internationally — a rule that often confuses first-time callers.

Italy Country Code and Dialing Format

Italy's international dialing code is +39. To call from the United States, dial 011 (or use + on smartphones), then 39, then the Italian phone number.

Complete format: 011 + 39 + Italian phone number

Italy's Unique Dialing Rule

Italy has one unusual rule compared with most countries. For landline numbers, the leading zero must remain even when calling internationally.

Domestic Rome number: 06 1234 5678

International dialing format: +39 06 1234 5678

This rule often causes confusion for callers used to removing the trunk prefix in other countries.
