📍 Geographic Location of Krosno
Geographic Overview
The +48 13 area code is a geographic National Destination Code (NDC) assigned to the Krosno region in southeastern Poland. This area is part of the Subcarpathian Voivodeship (województwo podkarpackie) and encompasses the city of Krosno along with several surrounding counties, including Krosno County, Brzozów County, and parts of Jasło County. The region is known for its historical significance, the Bieszczady Mountains to the south, and its role as a center of the aviation and glass industries.
Dialing Formats
When dialing a number within the Krosno area code, the national subscriber number consists of the trunk prefix '0', the area code '13', followed by a 7-digit local number. For example, a local Krosno number might be formatted as 0 13 4xx xx xx when dialed domestically. However, the leading '0' is only used within Poland. For international callers, the country code +48 replaces the trunk prefix, so the same number would be dialed as +48 13 4xx xx xx.
Local calls within the same area code can often be made using only the 7-digit subscriber number, depending on the operator's dialing plan. However, for clarity and consistency, it is recommended to always use the full national or international format.
Geographic Coverage and Administration
The +48 13 code is administered by the Polish Office of Electronic Communications (UKE) and is allocated to fixed-line services. It serves not only the city of Krosno but also smaller towns and rural communities within the designated area. Key towns served by this code include Brzozów, Dukla, Jedlicze, and Rymanów. The area is well-connected via the DK28 and DK19 national roads, and the nearest major city is Rzeszów, which uses a different area code (+48 17).
Caller Instructions
For local callers (within Poland): To call a number in the Krosno area from another region, dial the trunk prefix '0', then '13', followed by the 7-digit subscriber number. For example, to call a number in Krosno from Warsaw, you would dial 0 13 4xx xx xx.
For international callers: Dial your country's international access code (e.g., 011 from the US/Canada, 00 from most European countries), then Poland's country code '48', then the area code '13' (without the leading '0'), followed by the 7-digit subscriber number. For instance, from the UK, you would dial 00 48 13 4xx xx xx.
As of 2025, there are no overlay codes in this region, meaning the +48 13 code is unique to the Krosno area. However, number portability allows subscribers to retain their numbers when changing operators, so a number with this prefix may not always be physically located in the Krosno region.
