Area Code 84 – Siofok

Overview of Hungary's +36 84 Geographic Area Code

The +36 84 area code is a geographic National Destination Code (NDC) within the Hungarian numbering plan, administered by the National Media and Infocommunications Authority (NMHH). It serves the Balaton region's southeastern shore, with Siófok as its primary city. This code covers Siófok and the surrounding settlements, including Balatonföldvár, Zamárdi, Balatonszárszó, and Balatonvilágos, along the southern shore of Lake Balaton. The region is a major domestic and international tourist destination, known for its beaches, festivals, and wine regions.

Geographic Coverage and Administrative Jurisdiction

The 84 code is assigned to the geographic area of Somogy County, specifically the Siófok district. It encompasses both the urban center of Siófok and the adjacent lakeside communities. As a geographic code, it is tied to a physical location, and calls are routed based on the fixed-line network infrastructure. The area is served by Magyar Telekom, Digi, and other licensed fixed-line operators, with number portability allowing subscribers to retain their numbers when changing providers within the same geographic area.

Dialing Formats and Usage

When calling a fixed-line number in the Siófok area from within Hungary, subscribers must dial the national trunk prefix 06, followed by the area code 84 and the subscriber's 6- or 7-digit local number. For example, a local Siófok number might be dialed as 06 84 123 456. From abroad, callers dial the international access prefix (e.g., 00 from most countries), then Hungary's country code +36, followed by the area code without the leading zero, and the local number: +36 84 123 456. It is important to note that the area code is an integral part of the national significant number (NSN), which is 8 or 9 digits long when including the area code.

Overlay and Numbering Considerations

Currently, the 84 area code does not have an overlay code; it is a standalone geographic code. However, as with all Hungarian geographic codes, number portability is available, meaning that a subscriber can switch from one fixed-line operator to another while retaining their geographic number. This does not change the geographic significance of the code. For callers, it is essential to always include the area code when dialing from a mobile phone, even if the call is local, as mobile networks require the full national number.

Practical Guidance for Callers

For local callers within the 84 area, dialing the 6-digit subscriber number alone may work for calls within the same exchange, but it is safer to use the full national format. For international callers, always drop the leading zero of the area code. For example, a tourist calling a hotel in Siófok from the United States would dial 011 36 84 123 456. When receiving calls from abroad, Hungarian numbers are typically displayed in international format, starting with +36 84.

Understanding the correct dialing procedures ensures seamless connectivity to businesses and residents in this vibrant Hungarian lakeside region.
