Area Code 5346 – Karlovka, Poltava

Geographic Overview and Jurisdiction

The +380 5346 dialing prefix is a geographic National Destination Code (NDC) assigned to the city of Karlovka and its surrounding administrative district within the Poltava Oblast of central Ukraine. This code falls under the broader Poltava regional numbering plan (534x), which is managed by the Ukrainian State Enterprise of Communications (Ukrposhta) under the authority of the National Commission for State Regulation of Communications and Informatization. The Karlovka district is an agricultural and light-industrial area, with the city itself serving as the administrative center. The numbering area encompasses the urban population of Karlovka as well as adjacent rural communities, all of which share the same local exchange infrastructure.

Dialing Formats and Call Routing

For domestic callers within Ukraine, the number is dialed in the format 0 5346 XX-XX-XX, where the leading '0' is the trunk prefix used to access the national long-distance network. The complete national significant number (NSN) consists of 9 digits: the NDC '5346' followed by a 5-digit subscriber number. Internationally, callers must replace the trunk prefix with Ukraine's country code, resulting in +380 5346 XX-XX-XX. This format is compliant with ITU-T E.164 recommendations.

Local calls within the Karlovka exchange area may be possible by dialing only the 5-digit subscriber number, depending on the specific operator's local dialing plan. However, for clarity and to avoid misrouting, it is recommended to always use the full national or international format when dialing from a mobile phone or from outside the immediate local area.

Geographic vs. Non-Geographic Nature

As a geographic code, 5346 is tied to a physical location. This has implications for tariffing: calls to this number are typically charged based on the distance from the caller's location, although many modern mobile tariffs treat all national calls equally. The code is not portable outside the Karlovka district; if a subscriber moves to another region, they must obtain a new local number. This is in contrast to mobile prefixes (e.g., +380 50, +380 67), which are non-geographic and allow number portability across the entire country.

Caller Instructions

For callers within Ukraine: dial 0 5346 [subscriber number] from any fixed or mobile phone. For international callers: dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 380 5346 [subscriber number]. Ensure you omit the leading '0' of the national trunk prefix when calling from abroad. For example, to reach a subscriber whose local number is 12345, an international caller would dial +380 5346 12345.

No overlay codes are currently active in the Karlovka area, so the 5346 code is the sole geographic prefix for the district. As with all fixed-line services in Ukraine, calls to this number are routed over the PSTN, and VoIP services may also terminate to this number, but the geographic association remains unchanged.
