Area Code 58 – North Khorasan

Overview of Area Code +98 58

Area code 58 is the National Destination Code (NDC) for the North Khorasan Province in Iran. This geographic code is assigned under the country's national numbering plan, which follows ITU-T E.164 recommendations. The province, with its capital at Bojnord, is located in the northeastern part of the country, bordering Turkmenistan. The code covers all landline telephone services within the province's administrative boundaries.

Geographic Coverage and Major Cities

The +98 58 area code encompasses the entire province, including the following key cities and districts:

• Bojnord (provincial capital)
• Shirvan
• Esfarayen
• Faruj
• Garmeh
• Jajarm
• Maneh and Samalqan
• Raz and Jargalan

All fixed-line subscribers within these regions share the same NDC, and local calls between them do not require the area code.

Dialing Formats

For callers within Iran, the national trunk prefix 0 is used before the area code. The full national format is:

0 58 XXXX XXXX

For international callers, the Iranian country code +98 is used, and the leading zero of the national prefix is dropped. The international format is:

+98 58 XXXX XXXX

For example, a landline number in Bojnord might be +98 58 3222 1234. When dialing from abroad, you would enter the plus sign, the country code 98, the area code 58 (without the leading 0), and then the 8-digit subscriber number.

Local and International Call Instructions

To call a fixed line in North Khorasan from another province in Iran, dial 058 followed by the 8-digit local number. If you are calling from within the same area code, you can dial the 8-digit number directly without the area code. For international callers, the process is to dial the international access prefix (e.g., 00 or +), then 98, then 58, and finally the local number.

Overlay and Numbering Considerations

Currently, there is no overlay code for North Khorasan; the 58 code is exclusively used for the province. However, as with many regions, the number of fixed lines may expand, and the 8-digit subscriber number provides ample capacity. The numbering plan is closed, meaning that all national numbers have a fixed length of 10 digits (including the leading 0). This ensures uniformity and simplifies routing.

Technical Notes

Fixed-line services in Iran are provided by the Telecommunication Company of Iran (TCI) and other licensed operators. The network supports traditional PSTN services, and many lines are also enabled for ADSL and VoIP services. However, the area code remains geographic, meaning that the number is tied to a physical location. If a subscriber moves to another province, they must obtain a new number with the corresponding area code.
