Geographic Overview
The Hungarian area code +36 42 is a geographic National Destination Code (NDC) assigned to the city of Nyíregyháza and its surrounding administrative district in Szabolcs-Szatmár-Bereg County, located in the Northern Great Plain region of Hungary. Nyíregyháza is the county seat and the seventh-largest city in Hungary, serving as a major economic, cultural, and transportation hub for the northeastern part of the country. The code covers the urban area of Nyíregyháza, including its agglomeration and several nearby settlements within the local catchment area defined by the National Media and Infocommunications Authority (NMHH).
Dialing Formats
When calling a fixed-line subscriber in Nyíregyháza from within Hungary, you must use the national trunk prefix 0 followed by the area code and the subscriber's six-digit local number. The national format is: 0 42 XXX XXX.
For international callers, the Hungarian country code (+36) replaces the trunk prefix, and the leading zero of the area code is dropped. The international format is: +36 42 XXX XXX.

Caller Instructions
- Local callers within the Nyíregyháza area may often dial the six-digit subscriber number directly without the area code, depending on their service provider and the exact tariff zone. However, for clarity and to avoid misdialing, it is recommended to always use the full national format.
- National callers from other Hungarian cities must dial the trunk prefix 0 before the area code: 0 42 XXX XXX.
- International callers should dial the international access prefix of their country (e.g., 00 from most European countries, 011 from North America), followed by Hungary's country code 36, then the area code 42 without the leading zero, and the local six-digit number.
Overlay and Numbering Plan Considerations
As of the current NMHH numbering plan, there is no overlay code for the Nyíregyháza area. The area code 42 is exclusively assigned to this geographic region. Subscriber numbers are six digits long, and the total length of a national significant number (NSN) is eight digits (excluding the trunk prefix). The Hungarian numbering plan is closed, meaning that the trunk prefix is always required for national calls to geographic numbers, even for local calls if dialing from a mobile phone.
For businesses and residents, it is essential to use the correct format to ensure proper routing through the PSTN and VoIP networks. When porting a fixed-line number to a VoIP provider, the geographic significance may be retained for emergency services and regulatory purposes, but the number remains associated with the Nyíregyháza area.
