Overview of Area Code +36 25
Area code 25 is a geographic National Destination Code (NDC) assigned to the city of Dunaújváros and its surrounding administrative district in central Hungary. This code is part of the Hungarian public switched telephone network (PSTN) and is used for fixed-line services within the designated numbering area. The region is located along the Danube River, approximately 70 kilometers south of Budapest, and serves as an important industrial and commercial hub.
Geographic Coverage and Administrative Jurisdiction
The +36 25 area code covers Dunaújváros itself, as well as several nearby towns and villages within Fejér County. Key localities served include Dunaújváros, Rácalmás, Kulcs, Baracs, and Nagyvenyim, among others. The numbering area is defined by the National Media and Infocommunications Authority (NMHH) and is aligned with the administrative boundaries of the local government districts.
Dialing Formats and Instructions
For callers within Hungary, the national trunk prefix is 06. To call a fixed-line number in Dunaújváros from another Hungarian city, you would dial 06 25 followed by the local subscriber number. For example, a local number might be 123 4567, so the full national dialing format would be 06 25 123 4567.
For international callers, the Hungarian country code is +36. Thus, the same number would be dialed as +36 25 123 4567 from abroad. It is important to omit the leading zero of the national prefix when dialing internationally.
Number Structure and Length
Geographic numbers in Hungary typically consist of the NDC (area code) plus a subscriber number. For area code 25, subscriber numbers are generally 7 digits in length, resulting in a total national significant number (NSN) of 9 digits (excluding the leading national trunk prefix). This structure complies with ITU-T E.164 recommendations.
Overlays and Numbering Changes
As of the current numbering plan, there are no overlay codes or recent changes affecting area code 25. The code remains exclusively assigned to the Dunaújváros geographic area. However, subscribers should be aware that number portability allows fixed-line numbers to be moved to other operators, but the geographic significance of the code is retained for routing purposes.
Practical Guidance for Callers
When calling from a mobile phone within Hungary, it is common to use the national format (06 25 ...) or the international format (+36 25 ...), both of which are valid. For local callers within the same area code, it may be possible to dial only the subscriber number (7 digits) without the area code, depending on the operator's dialing plan. However, for clarity and consistency, it is recommended to always include the area code when dialing from any other location.
