Area Code 35 – Balassagyarmat

Geographic Overview

The +36 35 country and area code combination corresponds to a geographic numbering area in Hungary, specifically assigned to the town of Balassagyarmat and its surrounding administrative district in Nógrád County, Northern Hungary. This region lies along the Ipoly River near the Slovak border and includes smaller settlements within the Balassagyarmati járás (district). The code is part of Hungary's closed numbering plan, where the full national significant number (NSN) consists of eight digits after the country code, including the leading area code digit.

Dialing Formats

For domestic calls within Hungary, subscribers must dial the area code without the international prefix. To reach a local number, the format is 35 XX XX XX (where X represents the subscriber's seven-digit local number). For example, a local Balassagyarmat number might be dialed as 35 123 4567 from any other part of Hungary. When calling from abroad, the international format is +36 35 123 4567 or 0036 35 123 4567 using the international prefix from your country. The leading '0' used in domestic dialing is omitted when adding the +36 country code.

Jurisdictional and Regulatory Notes

The area code 35 is allocated under the Hungarian National Media and Infocommunications Authority (NMHH) and follows ITU-T E.164 recommendations. It is a geographic code, meaning the tariff and routing are based on the physical location of the fixed-line subscriber. Calls to numbers with this code are typically charged as national fixed-line rates when dialed from other Hungarian networks. As with all Hungarian geographic codes, number portability allows subscribers to retain their numbers when changing service providers, but the code remains associated with the original geographic area.

Caller Instructions

Local callers within the Balassagyarmat area may be able to dial only the seven-digit subscriber number without the area code, depending on their local exchange configuration. However, for clarity and to ensure successful connection, it is recommended to always include the area code when dialing from mobile phones or from outside the immediate local area. International callers must replace the trunk prefix '0' with the country code +36, and then dial the area code 35 followed by the subscriber number. For example, to call a business in Balassagyarmat from the United States, you would dial 011 36 35 123 4567.

Overlays and Future Considerations

Currently, there is no overlay code for the 35 area, meaning the area code uniquely identifies the Balassagyarmat region. However, as Hungary's telecommunication landscape evolves, VoIP and mobile services may influence numbering usage, but the geographic significance of the code remains unchanged for fixed-line services. Users should always verify the current dialing procedures with their service provider, especially when using corporate VoIP systems that may require alternative dialing formats.
