📍 Geographic Location of Gdańsk
Geographic Coverage and Administrative Jurisdiction
The +48 58 country-code prefix is the National Destination Code (NDC) assigned to the Tricity metropolitan area on Poland's Baltic coast. Its primary administrative center is Gdańsk, the capital of Pomeranian Voivodeship, with the numbering area extending to the neighboring cities of Gdynia and Sopot, as well as the surrounding counties (powiats) of Gdańsk, Gdynia, and Wejherowo. This geographic code covers a densely populated economic hub, including the Port of Gdańsk, the Lech Wałęsa Airport, and numerous business districts.
Dialing Formats and Caller Instructions
For domestic callers within Poland, the number is dialed in the national format: 58 XXX XX XX (where X represents the subscriber's seven-digit line number). The leading '0' trunk prefix is not required when dialing from a Polish mobile or fixed line, as the country uses closed numbering plan. International callers must dial +48 58 XXX XX XX or 0048 58 XXX XX XX (the latter using the international access code from most countries). When dialing locally within the 58 area, the full national number (including the area code) is still required, as Poland does not use local dialing without the area code.
Numbering Plan and Overlay Considerations
The 58 area code is a geographic NDC under the ITU-T E.164 standard. It is not overlaid with another code; the numbering capacity is sufficient for the region's demand. Subscriber numbers within the 58 area are seven digits long, and the total number length for international format is 11 digits (including the country code). The prefix is administered by the Polish Office of Electronic Communications (UKE), which allocates number ranges to fixed-line operators such as Orange Polska, T-Mobile Polska, and Netia, as well as alternative local carriers.
Usage and Practical Information
Numbers with the 58 prefix are primarily used for fixed-line PSTN and VoIP services. They are commonly associated with businesses, public institutions, and residential subscribers in the Tricity area. When calling from abroad, the cost is determined by the caller's international tariff, while domestic calls are typically included in flat-rate plans. For foreign callers, it is important to note that the plus sign (+) must be used when dialing from mobile phones to ensure proper international routing. Additionally, some businesses may use 58 numbers for fax lines or alarm systems, so callers should be aware of potential non-human responses.
