History
Italy introduced complete selection for geographic numbers in the late 1990s. The reform made the district code, including its initial 0, part of the number dialled for every fixed-line call. AGCOM’s service-based plan continues to reserve numbers beginning with 0 for geographic services and lists district indicators of two to four digits.
The official NDC is 040 and includes its leading 0.
