📍 Geographic Location of Hamadan province

Geographic Overview

The +98 81 area code is the National Destination Code (NDC) for the province of Hamadan in western Iran. This geographic code is assigned to the province's capital, Hamadan, and its surrounding counties, including Malayer, Nahavand, Tuyserkan, Asadabad, and Bahar. The region is known for its historical significance, with sites like the ancient Ecbatana, and its thriving agricultural and industrial sectors.

Dialing Formats

To call a fixed-line number in Hamadan from within Iran, subscribers must dial the trunk prefix '0' followed by the area code '81' and the local subscriber number. For example, a local number might be dialed as 081-3XXX-XXXX (where '3' is the central office code). The complete national format is 0813XXXXXXX (10 digits including the leading '0').

For international callers, the leading '0' is omitted, and the country code for Iran (+98) is used. Thus, the same number would be dialed as +98 813XXXXXXX from abroad. It is crucial to drop the trunk prefix '0' when dialing internationally.

Caller Instructions

Local callers within Hamadan: When calling another fixed line within the same area code, you may need to dial the full national number (including the area code) depending on the current dialing plan. As of recent years, Iran has moved towards mandatory 10-digit dialing for all fixed-line calls, so always dial 081 followed by the subscriber number.
National callers from other provinces: Dial 081 followed by the local number.
International callers: Dial your country's exit code (e.g., 00 from most countries), then 98 (Iran's country code), then 81, and then the local subscriber number. Do not include the '0' before '81'.

Number Structure and Overlays

Fixed-line numbers in Hamadan are typically 8 digits long (excluding the leading '0'). The first digit of the subscriber number often indicates the central office or district. Currently, there are no overlay codes in Hamadan; the 81 code is exclusively for the province. However, due to increasing demand, the Telecommunications Company of Iran (TCI) may introduce additional numbering resources in the future.

Technical Notes

Calls to Hamadan from mobile phones within Iran are routed via the PSTN and may incur standard national long-distance charges. VoIP services may also use this code, but users should verify the exact dialing format with their service provider.
