Area Code 44 – Sisak-Moslavina

Overview

The +385 44 country calling code and area code combination corresponds to the Sisak-Moslavina County in central Croatia. This geographic prefix is part of the national numbering plan administered by the Croatian Regulatory Authority for Network Industries (HAKOM) under the ITU-T E.164 standard. The area code 44 is assigned to the region encompassing the city of Sisak, the county seat, and its surrounding municipalities, including Petrinja, Kutina, Novska, and Glina. The numbering area is classified as a geographic destination, meaning that the prefix is tied to a specific physical territory and is used for fixed-line (PSTN) services.

Geographic Coverage and Administrative Jurisdiction

The Sisak-Moslavina County is one of Croatia's 21 counties, located southeast of the capital Zagreb, along the Sava and Kupa rivers. The area code 44 covers the entire county, which is subdivided into several local administrative units. The primary cities served by this prefix include:

• Sisak – the county capital and largest urban center, known for its historical significance and industrial base.
• Petrinja – a town near Sisak, notable for its baroque architecture and recent post-earthquake reconstruction.
• Kutina – an industrial town in the eastern part of the county.
• Novska – a town located at the crossroads of major transport routes.
• Glina – a town in the southern part of the county.

All fixed-line telephone numbers within this region share the 44 area code, and no overlay codes have been implemented. Therefore, the area code is mandatory for all calls, even within the same locality.

Dialing Formats and Caller Instructions

For domestic callers within Croatia, the national significant number (NSN) for a Sisak-Moslavina fixed-line subscriber is 10 digits long, beginning with the trunk prefix '0' followed by the area code '44' and the subscriber number (typically 6 digits). The local number format is 0 44 XXX XXX. When dialing from a foreign country, the international format is +385 44 XXX XXX, where the leading '0' is omitted.

Example: A local number in Sisak might be 044 123 456. To call this number from abroad, you would dial +385 44 123 456.

For callers within the same area code, it is still necessary to dial the full national number, including the area code, as per Croatian numbering regulations. No local dialing without the area code is permitted.

Technical Considerations

Geographic numbers in Croatia are primarily associated with traditional PSTN lines, but they may also be used for VoIP services provided by licensed operators. Number portability allows subscribers to retain their geographic number when switching providers, but the number remains tied to the geographic location for routing purposes. Emergency services (112) and other short codes are accessed without the area code.

For international callers, it is essential to use the correct country code (+385) and to replace the leading '0' of the area code with the international access prefix. This ensures proper routing through the international gateway to the Croatian PSTN.
