📍 Geographic Location of Keszthely
Geographic Overview
The +36 83 area code is a geographic National Destination Code (NDC) assigned to the Keszthely telephone exchange area in Hungary. Keszthely is a historic town located on the western shore of Lake Balaton, within Zala County. The area code serves Keszthely itself and the surrounding settlements, including Hévíz, Gyenesdiás, Vonyarcvashegy, and Balatongyörök. These localities form part of the Balaton tourism region, which influences the demand for both fixed-line and VoIP services.
Dialing Formats
When calling a fixed-line number in the Keszthely area from within Hungary, subscribers must dial the national trunk prefix 06, followed by the area code 83 and the subscriber's 6-digit number. For example, a local number might be dialed as 06 83 123 456. From abroad, callers must use the international prefix (typically + or 00), followed by Hungary's country code 36, the area code 83 (without the leading zero), and the 6-digit subscriber number. Thus, the same number would be dialed as +36 83 123 456.
Geographic Significance
The Keszthely area code is part of Hungary's geographic numbering plan, which means that the tariff for calls to this number is typically based on the distance from the caller's location, although many operators now offer flat-rate national calling plans. The area code is administered by the National Media and Infocommunications Authority (NMHH). As with all Hungarian geographic codes, number portability is available, allowing subscribers to retain their numbers when switching between fixed-line operators, but the geographic significance of the code remains tied to the Keszthely region.
Caller Instructions
For local callers within the Keszthely area, it is possible to dial the subscriber number directly without the area code, depending on the local dialing plan. However, for clarity and to avoid errors, it is recommended to always use the full national format.

For example, a caller from the United States would dial 011 36 83 123 456, while a caller from the United Kingdom would dial 00 36 83 123 456.
Businesses and residents in the Keszthely area often use these numbers for customer service and administrative lines. When contacting such numbers from abroad, be aware of time zone differences (Central European Time, UTC+1, with daylight saving time in summer).
