📍 Geographic Location of Humenne
Geographic Coverage and Administrative Jurisdiction
The +421 57 country and area code combination routes calls to the geographic region of Humenné, a district town in the Prešov Region of eastern Slovakia. The code serves the Humenné District (okres Humenné) and its surrounding municipalities, including the towns of Snina and Medzilaborce, as well as numerous villages within the Laborec and Cirocha river valleys. Administratively, this area falls under the Košice self-governing region for certain decentralized state functions, though it remains part of the Prešov Region for territorial administration. The numbering area is defined by the Slovak Telecommunication Office (Úrad pre reguláciu elektronických komunikácií a poštových služieb) under the national numbering plan, which follows ITU-T E.164 recommendations.
Dialing Formats and Caller Instructions
Within Slovakia, calls to Humenné landlines require dialing the national trunk prefix 0 followed by the area code 57 and the subscriber number. The full national format is 0 57 XXX XXXX (where X represents the local seven-digit subscriber number). For example, a local call from Bratislava would be dialed as 057 XXX XXXX.
For international callers, the country code +421 replaces the trunk prefix. Thus, from abroad, you would dial +421 57 XXX XXXX. Note that the leading zero is omitted when dialing from outside Slovakia. For instance, to reach a Humenné landline from the United States, you would dial 011 421 57 XXX XXXX (or +421 57 XXX XXXX on a mobile phone).
Overlays and Numbering Considerations
Currently, the 57 area code does not have an overlay code; it is the sole geographic code for the Humenné region. However, subscribers may have migrated to VoIP or alternative services, but the geographic significance remains for number portability. When dialing locally within the same area code, the national format with the trunk prefix is still required for calls from other regions, but local calls within Humenné may be dialed using only the subscriber number if your operator supports it, though this is not standard across all networks.
For callers using mobile phones, it is essential to include the area code even when calling from within the same region, as mobile numbers are non-geographic and require full national dialing.
