📍 Geographic Location of Tatabanya
Geographic Overview
The Hungarian national destination code (NDC) 34 is a geographic area code assigned to the city of Tatabánya and its surrounding administrative district in Komárom-Esztergom County, northwestern Hungary. Tatabánya serves as the county seat and is a major industrial and transportation hub, located roughly 55 kilometers west of Budapest. The code covers the city itself and nearby settlements within the local calling area, including but not limited to Tata, Oroszlány, and Környe.
Dialing Formats
When calling a landline in Tatabánya from within Hungary, subscribers use the national trunk prefix 0 followed by the area code 34 and the subscriber's 7-digit local number. For example, a local number such as 123-4567 would be dialed as 06 34 123 4567 from any other part of the country. From abroad, callers must use the international access prefix (typically 00 or +), followed by Hungary's country code 36, then the area code without the leading zero, and the local number: +36 34 123 4567.
Caller Instructions
For local callers within the Tatabánya area, it is possible to dial only the 7-digit subscriber number for calls within the same geographic charging group. However, for clarity and to avoid misdialing, it is recommended to always use the full national format. For international callers, ensure you omit the trunk prefix '0' when dialing from outside Hungary. If you are using a mobile phone, you can typically replace the international prefix with '+', so the number becomes +36 34 123 4567.
Numbering Plan Considerations
Hungary's geographic numbering plan follows ITU-T E.164 recommendations. The area code 34 is part of the closed numbering plan, meaning that the full national number (including the leading '0') is always 9 digits long (0 + area code + 7-digit subscriber number). There are no overlay codes in this area; the 34 code is exclusively used for Tatabánya and its environs. As of the latest updates, no major renumbering is planned, but subscribers should be aware that number portability allows users to retain their geographic number when moving to a different service provider, even if they switch to VoIP or mobile services, though the geographic association remains.
