Area Code 18 – Nowy Sącz

Geographic Coverage and Administrative Jurisdiction

The +48 18 country and area code combination designates a specific geographic numbering area within the Republic of Poland, aligned with the ITU-T E.164 international public telecommunication numbering plan. The area code 18 is assigned to the Nowy Sącz region, which is part of the Lesser Poland Voivodeship (województwo małopolskie) in southern Poland. This code covers the city of Nowy Sącz itself, as well as the surrounding counties (powiaty) of Nowy Sącz and Gorlice, and includes towns such as Krynica-Zdrój, Muszyna, Piwniczna-Zdrój, and Stary Sącz. The administrative jurisdiction is the Nowy Sącz delegation of the Office of Electronic Communications (UKE), which oversees local numbering resources.

Primary Cities and Local Dialing Format

The primary urban center served by this code is Nowy Sącz, a city with a population of approximately 84,000, situated at the confluence of the Dunajec and Kamienica rivers. Other significant localities within the 18 code area include Gorlice, a town known for its oil industry heritage, and the popular spa towns of Krynica-Zdrój and Muszyna. For local calls within the same area code, subscribers dial the seven-digit subscriber number directly, omitting the trunk prefix and area code. For example, to call a landline in Nowy Sącz from another landline within the same code, one would dial 123 45 67 (without the leading 0).

International and National Dialing Formats

For callers outside Poland, the international format is +48 18 followed by the seven-digit subscriber number, e.g., +48 18 123 45 67. When calling from a Polish mobile phone or from another area code within Poland, the national format requires the trunk prefix 0, so the number becomes 0 18 123 45 67. It is important to note that the leading 0 is not part of the country code and is only used domestically. The area code 18 is a geographic code, meaning that the tariff for calls to these numbers is typically based on the geographic location of the called party, although many Polish operators now offer flat-rate national calling plans.

Overlay Considerations and Numbering Plan

Currently, there is no overlay code for the Nowy Sącz area; the 18 code is the sole geographic area code for this region. Subscriber numbers within this code are seven digits long, and the total number of assignable numbers is limited by the capacity of the local exchange. The Polish numbering plan follows the closed numbering system, meaning that the full national significant number (NSN) consists of nine digits, including the area code (without the trunk prefix 0). Thus, the NSN for a Nowy Sącz number is 18 123 45 67, which is used for international dialing after the +48 country code.

Caller Instructions

For local callers within the Nowy Sącz area, simply dial the seven-digit subscriber number. For callers from other parts of Poland, dial 0 18 followed by the subscriber number. For international callers, dial the international access prefix (e.g., 00 from most countries, or + from mobile phones), then 48, then 18, and the subscriber number. It is advisable to check with your service provider for any specific dialing requirements, especially when using VoIP or mobile services.
