📍 Geographic Location of Karlovac
Geographic Coverage and Administrative Jurisdiction
The +385 47 country-code prefix is the National Destination Code (NDC) assigned to the Karlovac geographic numbering area in Croatia. This area corresponds to the Karlovac County (Karlovačka županija), an administrative region in central Croatia. The primary city served is Karlovac, the county seat, located at the confluence of the Kupa and Korana rivers. The numbering area also encompasses surrounding towns and municipalities, including Duga Resa, Ogulin, Slunj, Ozalj, and Vojnić. The prefix is used for fixed-line (PSTN) services within this region, and calls to these numbers are routed via the Croatian public switched telephone network.
Dialing Formats and Number Structure
When dialing a Karlovac fixed-line number domestically, subscribers within Croatia use the trunk prefix '0' followed by the area code and the subscriber's local number. For example, a local Karlovac number might be dialed as 047 123 456. Internationally, callers must use the Croatian country code '+385', drop the leading '0', and dial +385 47 123 456. The national significant number (NSN) for Croatian fixed-line numbers is eight digits, including the NDC. Thus, the subscriber number after the area code is typically six digits long, though some legacy numbers may have fewer digits. Always verify the exact number length with your service provider or the Croatian regulatory authority (HAKOM).
Overlay and Numbering Plan Considerations
As of the current Croatian numbering plan, there is no overlay code for the Karlovac area; the 47 prefix remains the sole geographic NDC for this region. However, number portability allows subscribers to retain their 47 numbers when switching operators, even if they move outside the geographic area, provided the service is technically feasible. This means that a call to a 47 number may terminate at a location outside Karlovac County, but the caller is still charged according to the geographic rate for fixed-line calls.
Caller Instructions
For local callers within the Karlovac area, dialing the subscriber number alone (without the area code) may be possible for calls within the same exchange, but it is safer to always include the area code. For domestic callers outside the 47 area, dial 0 47 followed by the subscriber number. For international callers, dial +385 47 followed by the subscriber number. Ensure you have the correct international exit code if calling from a landline (e.g., 00 from most European countries).
