Area Code 232 – Izmir

Overview of Area Code +90 232

Area code 232 is the geographic National Destination Code (NDC) assigned to the province of İzmir in the Republic of Türkiye. As part of the Turkish numbering plan, which follows ITU-T E.164 recommendations, the code is used for fixed-line (PSTN) services within the province. The complete international dialing format for a number in İzmir is +90 232 XXX XX XX, where the subscriber number is 7 digits long, resulting in a total national significant number length of 10 digits (excluding the leading trunk prefix '0').

Geographic Coverage and Administrative Jurisdiction

The 232 area code covers the entire İzmir Province, including its metropolitan municipality and all surrounding districts. Key cities and towns served by this code include the provincial capital İzmir (often referred to as Smyrna historically), along with major districts such as Karşıyaka, Bornova, Buca, Konak, Çiğli, Gaziemir, and Menemen. The code is administered by the Information and Communication Technologies Authority (BTK) of Türkiye and is allocated exclusively for geographic fixed-line services. Mobile services in the region use separate non-geographic prefixes (e.g., 501, 532, 541) and are not associated with the 232 code.

Dialing Formats and Instructions

For callers within Türkiye, dialing a fixed-line number in İzmir requires the national trunk prefix 0 followed by the area code and subscriber number: 0 232 XXX XX XX. For example, to call a number in İzmir from Istanbul, you would dial 0 232 456 78 90. For international callers, the format is +90 232 XXX XX XX (or 00 90 232 ... from most countries). For example, a caller from the United States would dial 011 90 232 456 78 90, while a caller from the United Kingdom would dial 00 90 232 456 78 90. It is important to note that the leading '0' is not used when dialing from abroad.

Overlay and Numbering Considerations

As of the latest BTK updates, there is no overlay code for the 232 area; the province is served solely by this single geographic code. However, due to increasing demand for fixed-line services, the BTK has implemented number conservation measures, but the 7-digit subscriber number format remains standard. Callers should always verify the complete number, as some businesses may use non-geographic numbers (e.g., 444 or 850) for customer service, which are not tied to the İzmir area.

Practical Information for Callers

When calling İzmir from abroad, be mindful of time zone differences (Türkiye is UTC+3 year-round). Also, ensure you have the correct country code (+90) and omit any leading zero from the area code. For local calls within İzmir, the area code is often omitted when dialing between fixed-line numbers in the same province, but with the current numbering plan, it is recommended to always include the area code to avoid misdialing, especially for mobile-to-fixed calls. For assistance, international operators can help with any dialing uncertainties.
