📍 Geographic Location of Palermo
Geographic Coverage and Administrative Jurisdiction
The Italian country code +39, combined with the geographic prefix 091, routes calls to the Metropolitan City of Palermo, the capital of the autonomous region of Sicily. This numbering area encompasses the city of Palermo and its surrounding municipalities, including Monreale, Bagheria, Ficarazzi, Villabate, Misilmeri, and Partinico. The prefix is assigned under the national numbering plan administered by the Autorità per le Garanzie nelle Comunicazioni (AGCOM) and is classified as a geographic National Destination Code (NDC).
Dialing Formats and Number Structure
Within Italy, calls to Palermo require the full national significant number: the trunk prefix 0 followed by the area code 091 and the subscriber number, which typically consists of 6 to 7 digits. Thus, a local call is dialed as 091 XXX XXXX or 091 XXX XXX depending on the specific line. For international callers, the Italian country code +39 is used without the leading 0, so the format becomes +39 091 XXX XXXX. Note that Italian mobile numbers are not prefixed with 0, but geographic numbers always retain the 0 when dialed domestically.
Overlay and Numbering Considerations
As of 2025, the 091 area code does not have an overlay; it remains the sole geographic code for the Palermo region. However, number portability allows subscribers to retain their 091 numbers when switching fixed-line operators, and in some cases, businesses may use non-geographic numbers for customer service lines. For callers, it is essential to include the 0 when dialing from within Italy, as omitting it will result in an invalid number.
Caller Instructions
- Local callers (within Palermo): Dial the full number including the area code, e.g., 091 123 4567.
- Domestic callers from other Italian cities: Dial 091 followed by the subscriber number, e.g., 091 123 4567.
- International callers: Dial your country's exit code, then 39, then 091 and the subscriber number, e.g., +39 091 123 4567.
This prefix is exclusively for fixed-line services; mobile numbers in Italy begin with 3 and are non-geographic. When calling a Palermo landline from abroad, always drop the leading 0 of the area code after entering +39.
