📍 Geographic Location of Heart
Overview of Afghanistan Area Code 40
Area code 40 is the National Destination Code (NDC) assigned to the city of Herat (also spelled Heart) and its surrounding province in the Islamic Republic of Afghanistan. This geographic code is part of the country's public switched telephone network (PSTN) and is used for fixed-line (landline) services within the Herat region. The code follows the ITU-T E.164 international numbering standard, ensuring seamless global routing.
Geographic Coverage and Administrative Jurisdiction
The 40 code covers the entire Herat Province, which is one of the largest provinces in Afghanistan, located in the western part of the country. The primary city served is Herat, the third-largest city in Afghanistan and a major economic and cultural hub. The code also serves smaller districts and towns within the province, including Guzara, Injil, Karukh, and Kushk. The administrative jurisdiction for this code is the Afghan Telecommunication Regulatory Authority (ATRA), which oversees the allocation and management of all national numbering resources.
Dialing Formats and Caller Instructions
For callers within Afghanistan, the local dialing format for a landline number in Herat is: 040 XXXXXX (where XXXXXX is the six-digit subscriber number). Note that the leading '0' is the trunk prefix used for domestic calls. For international callers, the format is: +93 40 XXXXXX (or 0093 40 XXXXXX). The country code for Afghanistan is +93, and the leading '0' is dropped when dialing from abroad.
Example: A local call to a Herat landline would be dialed as 040 123456. An international caller from the United States would dial 011 93 40 123456 (using the US exit code), while a caller from the United Kingdom would dial 00 93 40 123456.
Overlay and Numbering Considerations
As of the latest ATRA guidelines, there is no overlay code for the Herat area. The 40 code is exclusively used for fixed-line services in the region. However, due to the growth of mobile and VoIP services, some businesses may use virtual numbers with the 40 code, but these are still routed to fixed-line infrastructure. Callers should be aware that mobile numbers in Afghanistan have distinct prefixes (e.g., 70, 74, 77) and are non-geographic, so they are not dialed with the 40 area code.
Practical Tips for Callers
When calling a Herat landline from a mobile phone within Afghanistan, it is essential to include the trunk prefix '0' (e.g., 040 XXXXXX). For international callers, always ensure you have the correct exit code for your country, followed by Afghanistan's country code (+93), then the area code without the leading '0', and finally the subscriber number. Due to potential network congestion or routing issues, it is advisable to verify the number with the recipient before making important calls.
