📍 Geographic Location of Genoa
Geographic Coverage and Administrative Jurisdiction
The Italian country code +39, when paired with the geographic prefix 010, routes calls to the province of Genoa (Genova), the capital of the Liguria region in northwestern Italy. This numbering area encompasses the city of Genoa and its metropolitan hinterland, including municipalities such as Arenzano, Cogoleto, Rapallo, and Chiavari along the Ligurian Riviera. As a geographic National Destination Code (NDC), 010 is assigned exclusively to fixed-line PSTN and VoIP services physically located within this administrative area, in accordance with the Italian Communications Regulatory Authority (AGCOM) numbering plan.
Dialing Formats and Numbering Structure
In the international format, a Genoese fixed-line number is written as +39 010 XXXXXXX, where the total subscriber number length is typically 7 digits after the prefix, resulting in a complete national significant number (NSN) of 10 digits (including the leading 0). When dialing domestically from any other Italian region, callers must include the trunk prefix 0, so the full number is 010 XXXXXXX. However, within the Genoa area, local calls can often be made using only the 7-digit subscriber number, omitting the 010 prefix, though this practice is becoming less common with the proliferation of mobile and VoIP services. For international callers, the format is +39 010 XXXXXXX (or 0039 010 XXXXXXX from many countries).
Overlay and Numbering Plan Considerations
Unlike some Italian metropolitan areas, Genoa does not currently have an overlay code; the 010 prefix remains the sole geographic code for the province. This means that number exhaustion is managed by reallocating freed numbers rather than introducing an additional area code. The prefix is strictly geographic, so calls to 010 numbers are always charged as fixed-line tariffs, regardless of whether the called line is a traditional PSTN or a VoIP service that is registered to a Genoese address.
Caller Instructions and Practical Notes
For local callers within Genoa, dialing the 7-digit subscriber number directly may work, but to avoid confusion and ensure connectivity, it is recommended to always dial the full 10-digit number including the 0. For callers from other Italian provinces, the full 010 prefix is mandatory. International callers must replace the leading 0 with the +39 country code. It is important to note that numbers starting with 010 are not mobile or toll-free; they are fixed-line services, so call charges are typically lower than mobile rates. If you are calling a Genoese business, expect standard business hours (CET/CEST) and be aware that some companies may use VoIP lines that still appear as 010 numbers.
