📍 Geographic Location of Jaszbereny
Geographic Overview
The +36 57 country-code prefix is a geographic National Destination Code (NDC) assigned to the Jászberény telephone exchange area in Hungary. This numbering area covers the city of Jászberény and its surrounding settlements within Jász-Nagykun-Szolnok County, located in the Northern Great Plain region of central Hungary. The area is part of Hungary's public switched telephone network (PSTN) and is administered by the National Media and Infocommunications Authority (NMHH).
Dialing Formats
When calling a landline in the Jászberény area from within Hungary, subscribers dial the national trunk prefix 06, followed by the area code 57 and the subscriber's six-digit local number. For example, a local number 123 456 would be dialed as 06 57 123 456 from any other Hungarian fixed or mobile line. From abroad, callers must use the international access prefix (typically 00 or +), followed by Hungary's country code 36, the area code 57 (without the leading trunk prefix), and the six-digit local number. Thus, the international format becomes +36 57 123 456.
Geographic Coverage
The Jászberény exchange area primarily serves the city of Jászberény, which is the administrative and economic center of the Jászság region. The numbering area may also include nearby towns and villages that are part of the local calling area, such as Jászárokszállás, Jászfényszaru, and Jászjákóhalma. These localities share the same NDC and are considered local calls when dialed between them, often at reduced tariffs compared to national calls.
Regulatory and Technical Notes
As a geographic number, the 57 prefix is tied to a physical location, but number portability allows subscribers to retain their numbers when moving to a different service provider within Hungary, provided the service address remains within the same geographic area. The Hungarian numbering plan follows ITU-T E.164 recommendations, and the maximum number length for geographic numbers is nine digits (including the leading zero for national dialing).
For international callers, it is important to omit the leading zero of the area code when dialing from abroad. Additionally, some VoIP and mobile services may route calls to geographic numbers at different rates, so users should consult their service provider for specific tariffs. The Hungarian telecommunications market is liberalized, and multiple operators offer fixed-line services in the Jászberény area, including Magyar Telekom, Digi, and Invitel, among others.
