Area Code 79 – Hyesan

Overview of Area Code 79 (Hyesan)

Area code 79 is a geographic National Destination Code (NDC) assigned to the city of Hyesan and its surrounding administrative region in Ryanggang Province, North Korea. Hyesan is the provincial capital and a key economic hub near the Chinese border. The code is used for fixed-line (PSTN) services within this designated numbering area.

Dialing Formats

When calling a landline in Hyesan from abroad, the international dialing format is:

• International: +850 79 XXXX XXX (replace X with the subscriber's local number)
• Domestic (within North Korea): 079 XXXX XXX (if calling from another province) or 79 XXXX XXX (if calling within the same province, depending on local routing rules)

For example, a typical international call to a Hyesan landline would be dialed as +850 79 123 4567 (fictional number). It is essential to omit the leading '0' from the area code when dialing from outside the country, as per ITU-T E.164 standards.

Geographic Coverage and Administration

The 79 area code covers Hyesan city and its adjacent counties within Ryanggang Province. This includes the urban center of Hyesan, which is the largest city in the province, and several smaller towns and rural communities. The numbering plan is administered by the Post and Telecommunications Corporation of the Democratic People's Republic of Korea (DPRK), the state-owned operator responsible for all fixed-line services in the country.

Caller Instructions

For international callers: Dial your country's international access code (e.g., 00 from most countries, or 011 from the United States), then the North Korea country code 850, followed by the area code 79 and the local subscriber number. Ensure you do not include any leading zeros.

For domestic callers: If you are calling from another province, you must dial the trunk prefix 0 followed by the area code 79 and the local number. If you are calling from within the same province, you may be able to dial the area code and number without the trunk prefix, but this depends on the specific local dialing procedures.

Overlay and Numbering Considerations

As of current numbering plan data, there are no overlay codes for the Hyesan area. The 79 code is exclusively assigned to this geographic region. However, due to the limited availability of public information about North Korea's telecommunications infrastructure, some details may vary. It is always recommended to verify the exact number length and dialing procedures with your telecommunications provider or the local operator.
