Area Code 24 – Zanjan province

Overview of Area Code +98 24

The international dialing code +98 24 is the geographic area code for the Zanjan province in northwestern Iran. This code is part of the national numbering plan administered under the ITU-T E.164 standard, and it is used for fixed-line (PSTN) services within the province. The province's administrative center, Zanjan city, along with its surrounding counties and rural districts, falls under this code.

Geographic Coverage and Administrative Jurisdiction

Area code 24 serves the entire province of Zanjan, which is bordered by East Azerbaijan, Gilan, Kurdistan, Hamadan, and Qazvin provinces. Key cities and towns within this code include Zanjan (the capital), Abhar, Khorramdarreh, Ijrud, Tarom, and Mahneshan. The code is exclusively assigned to fixed-line services; mobile numbers in Iran use separate non-geographic prefixes (e.g., 0910, 0935) and are not affected by this area code.

Dialing Formats

For callers within Iran, the national trunk prefix 0 is dialed before the area code. Therefore, a local number in Zanjan is dialed as 024-XXX XXXX (where X represents the subscriber digits). For international callers, the country code +98 is used, and the leading trunk prefix is omitted. The international format becomes +98 24-XXX XXXX. For example, a typical fixed-line number in Zanjan city might be +98 24 3312 4567.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Zanjan province; the 24 code is the sole geographic code for the region. However, as demand for fixed-line services evolves, the telecommunications regulator may introduce additional digits or overlay codes in the future. Subscriber numbers within this code are typically 8 digits long, making the total national significant number (NSN) 10 digits when including the area code.

Caller Instructions

Local callers within Zanjan can often dial the 8-digit subscriber number directly without the area code, depending on the local exchange configuration. However, it is always safe to dial the full national format (024-XXX XXXX) to avoid misrouting. Callers from other provinces must dial 024 followed by the subscriber number. International callers should replace the trunk prefix with the +98 country code, resulting in +98 24 XXX XXXX.

For VoIP and mobile users, the same dialing rules apply, but ensure that your service provider supports calls to Iranian geographic numbers. Rates for calling this code vary by carrier and destination, so check with your operator for applicable charges.
