Area Code 66 – Lorestan

Overview of Area Code +98 66

Area code +98 66 is the geographic National Destination Code (NDC) assigned to the province of Lorestan in the Islamic Republic of Iran. This code is part of the national numbering plan administered under ITU-T E.164, and it routes calls to fixed-line (PSTN) subscribers within the province. The province is located in the western part of Iran, and its administrative capital is Khorramabad. Other major cities and towns served by this code include Borujerd, Aligudarz, Dorud, Kuhdasht, Azna, and Nurabad.

Geographic Coverage and Jurisdiction

The +98 66 area code covers the entire province of Lorestan, which is divided into several counties. The code is used for all fixed-line telephone numbers in the province, regardless of the specific city or district. The province is bordered by Hamadan to the north, Isfahan to the east, Khuzestan to the south, and Kermanshah and Ilam to the west. The region is known for its mountainous terrain and historical sites, and it has a significant population that relies on both landline and mobile services.

Dialing Formats

When dialing a fixed-line number in Lorestan from within Iran, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The full national format is: 0 66 XXXX XXXX. For example, a local number in Khorramabad might be 0 66 3312 4567.

For international callers, the Iranian country code +98 is used, followed by the area code without the leading zero. The international format is: +98 66 XXXX XXXX. For instance, the same number would be dialed as +98 66 3312 4567 from outside Iran.

When calling within the same area code, local dialing may allow omitting the area code, but this depends on the specific telecom operator and the current numbering plan. However, for clarity and to avoid misdialing, it is recommended to always use the full national or international format.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Lorestan; the area code +98 66 is the sole geographic code for the province. Subscriber numbers are typically 8 digits long, making the total length of a national significant number (NSN) 10 digits (including the leading 0). The numbering plan is closed, meaning that the area code must always be dialed for calls from outside the local area.

Caller Instructions

• Local callers (within Lorestan): If your telephone service provider requires 10-digit dialing, dial 0 66 XXXX XXXX. Otherwise, you may dial only the 8-digit subscriber number for local calls, but this is not guaranteed across all operators.
• National callers (from other provinces in Iran): Dial 0 66 XXXX XXXX.
• International callers: Dial your country's exit code (e.g., 00 or +), then 98 66 XXXX XXXX.
