📍 Geographic Location of Kunduz
Overview of Area Code 51 (Kunduz, Afghanistan)
Area code 51 is the National Destination Code (NDC) assigned to the northern Afghan province of Kunduz under the ITU-T E.164 numbering plan for Afghanistan (Country Calling Code +93). This geographic code is used for fixed-line (PSTN) services within the province, covering the provincial capital Kunduz City and its surrounding districts, including Khanabad, Chahar Dara, Ali Abad, Dasht-e-Archi, and Imam Sahib. The code is administered by the Afghanistan Telecommunication Regulatory Authority (ATRA) and is allocated to fixed-line operators such as Afghan Telecom (Salam Network) and other licensed local carriers.
Dialing Formats and Usage
To call a fixed-line number in Kunduz from abroad, dial the international access prefix (e.g., 00 or +), followed by Afghanistan's country code 93, then the area code 51 (without the leading trunk prefix '0'), and finally the subscriber's 7-digit local number. For example, if the local number is 1234567, the international format is +93 51 1234567. Within Afghanistan, callers must dial the trunk prefix 0 before the area code: 0 51 1234567. The total number length after the country code is 9 digits (NDC + subscriber number), consistent with the national numbering plan.
Geographic Coverage and Administrative Significance
Kunduz Province is a major economic and agricultural hub in northern Afghanistan, bordering Tajikistan. The area code 51 serves not only the provincial capital but also key commercial and administrative centers. Due to the region's strategic location along the Kunduz River and its proximity to the Tajik border, the code is vital for trade, logistics, and humanitarian communications. Fixed-line penetration in the region remains limited compared to mobile services, but the code is essential for government offices, businesses, and international organizations operating in the province.
Caller Instructions and Considerations
For international callers, it is important to note that Afghan fixed-line numbers may experience routing delays or intermittent connectivity due to infrastructure challenges. Always verify the correct local number, as Afghan numbering can sometimes be presented with or without the leading '0'. For local callers, ensure you include the trunk prefix '0' when dialing from a mobile phone or another province. Overlay codes are not currently in use for Kunduz; the area code 51 is exclusive to this geographic region. If you are unsure about a number, contact the local operator or check with ATRA for the latest numbering updates.
