Area Code 0733 – Macerata

Geographic Coverage and Administrative Jurisdiction

The Italian country code +39, prefix 0733 is a geographic National Destination Code (NDC) assigned to the province of Macerata, in the Marche region of central Italy. The numbering area includes the city of Macerata (the provincial capital) and the surrounding municipalities, such as Corridonia, Pollenza, Tolentino, Treia, and others within the province's boundaries. The prefix is administered under the national numbering plan supervised by the Autorità per le Garanzie nelle Comunicazioni (AGCOM).

Dialing Formats and Usage

When calling a fixed-line number in Macerata from within Italy, subscribers must dial the full national significant number, which includes the trunk prefix '0' followed by the area code and the subscriber's local number. For example, a local number in Macerata might be dialed as 0733 123456 from a domestic landline or mobile phone. The '0' is an integral part of the national dialing sequence and must not be omitted when calling from within Italy.

For international callers, the Italian country code +39 is used, and the leading '0' of the area code is dropped. Thus, the same number would be dialed as +39 733 123456 from abroad. This format follows the ITU-T E.164 international numbering standard.

Numbering Plan and Overlay Considerations

Italian fixed-line numbers are typically 10 digits long (including the leading '0'), but the total length can vary. The Macerata area code 0733 is a geographic code, meaning that the tariff and routing are based on the physical location of the line. There are no overlay codes in this area; the prefix 0733 is exclusively used for the Macerata province. However, number portability allows subscribers to retain their numbers when switching operators, even if they move outside the geographic area, though the number's geographic association remains for administrative purposes.

Caller Instructions

For local callers within the Macerata area, it is still necessary to dial the full number, including the area code, because Italian dialing procedures require the entire national significant number for all calls, even within the same local area. This is a common practice in Italy, unlike some other countries where local calls may be dialed with only the subscriber number.

For foreign callers, it is essential to use the international prefix of their country (e.g., 00 from most European countries, 011 from North America) followed by Italy's country code 39 and then the area code without the leading zero. For example, a caller from the United States would dial 011 39 733 123456.

Service and Usage Notes

The 0733 prefix is used for PSTN (Public Switched Telephone Network) lines, as well as VoIP services that are assigned geographic numbers. As with all Italian geographic codes, calls to these numbers are typically charged at standard national rates, which may vary depending on the caller's operator and subscription plan. Emergency services are reached via 112 (single European emergency number) or 113 (Police), which are free and do not require an area code.
