📍 Geographic Location of Hun
Geographic Overview
The area code 57 is a geographic National Destination Code (NDC) within the Libyan telephone numbering plan, assigned to the city of Hun and its surrounding administrative district in the Al Jufrah Governorate. Hun serves as the capital of the Al Jufrah region and is a key oasis town in central Libya, situated along the historic trade routes connecting the coastal cities to the Fezzan region. The code covers the urban center of Hun as well as nearby settlements and rural areas that rely on the same fixed-line infrastructure.
Dialing Formats
When calling a fixed-line subscriber in Hun from within Libya, the national trunk prefix 0 is used before the area code. The complete national format is:
- 0 57 XXX XXX (where X denotes the subscriber number digits)
For international callers, the Libyan country code +218 is used, and the leading trunk prefix 0 is omitted. The international dialing format becomes:
- +218 57 XXX XXX
For example, a local call to a Hun number might be dialed as 057 123 456, while an international caller would dial +218 57 123 456.
Caller Instructions
Local callers within Libya should always include the trunk prefix 0 when dialing any fixed-line number outside their own local area. Even when calling from another city within Libya, the format 057 XXX XXX is required. International callers must replace the leading 0 with the country code +218 and then dial the area code without the trunk prefix. It is important to note that the Libyan numbering plan does not currently use area code overlays; each geographic region has a unique code, and no additional digit is required for local calls within the same exchange.
Technical Considerations
The 57 code is allocated exclusively to fixed-line PSTN services. As with other Libyan geographic codes, calls to these numbers are typically routed over the traditional circuit-switched network, although some operators have migrated to VoIP backhaul. Subscriber numbers in Hun are seven digits long, including the area code, which is consistent with the national fixed-line numbering scheme. When storing Libyan numbers in international format, it is recommended to use the plus sign (+) and country code to ensure proper global routing. For travelers or businesses, it is essential to verify the current dialing procedures with the local telecom operator, as network changes may occasionally affect routing.
