Area Code 0183 – Imperia

Geographic Overview

The area code 0183 is a geographic National Destination Code (NDC) assigned to the province of Imperia, located in the Liguria region of northwestern Italy. This code covers the westernmost part of the Italian Riviera, bordering France to the west. The principal city served is Imperia, which is the provincial capital. Other notable municipalities within this numbering area include Sanremo, Ventimiglia, Bordighera, and Taggia. The area is known for its tourism, flower industry, and coastal towns.

Dialing Formats

When calling a landline in the Imperia area from within Italy, subscribers must dial the full national significant number, which includes the trunk prefix 0 followed by the area code 183 and the subscriber number. The local subscriber numbers typically consist of 6 to 7 digits, making the complete national number 10 or 11 digits long (excluding the initial trunk prefix). For example, a local number might be formatted as 0183 123456 when dialed domestically.

For international callers, the Italian country code +39 is used, followed by the area code without the leading zero. Thus, the same number would be dialed as +39 183 123456 from outside Italy. It is important to note that Italy uses an open dialing plan; the leading zero is part of the national significant number and must always be included when dialing from within Italy, even for local calls. There are no separate local dialing prefixes; callers within the same area code must still dial the full number.

Overlays and Numbering

As of the latest ITU-T recommendations, no overlay codes have been introduced for the 0183 area. The numbering capacity is managed by the Italian Communications Regulatory Authority (AGCOM). Subscriber numbers within this area are allocated to fixed-line operators, and number portability is available, allowing users to retain their numbers when switching providers.

Caller Instructions

For local callers within the Imperia province, simply dial the full national number starting with 0183. For callers from other Italian regions, dial 0183 followed by the subscriber number. For international callers, replace the leading zero with the international access code (e.g., 00 from most European countries) and then dial 39 183 followed by the subscriber number. For example, a call from the United States would be made by dialing 011 39 183 123456.

It is also worth noting that mobile numbers in Italy always begin with 3 and are not affected by geographic area codes. Therefore, when calling a mobile phone in the Imperia area, you must dial the mobile number directly without the 0183 prefix.
