📍 Geographic Location of Warsaw
Overview of Area Code +48 22
Area code 22 is the geographic National Destination Code (NDC) for Warsaw, the capital of Poland, within the international dialing prefix +48. It serves the city proper and its immediate suburban areas, covering an administrative region that is home to over 1.8 million inhabitants. As a geographic code, it is allocated to fixed-line (PSTN) services and is also used by some VoIP providers that offer location-based numbers. The code is not portable to mobile networks, meaning that a number with the 22 prefix is permanently associated with the Warsaw area for routing purposes.
Geographic Coverage and Administrative Jurisdiction
The 22 code covers the entire capital city of Warsaw (Warszawa) and its surrounding counties within the Masovian Voivodeship. Key districts and towns served include Śródmieście (city center), Mokotów, Wola, Praga, Ursynów, and the suburban municipalities of Piaseczno, Pruszków, and Legionowo. The code is administered by the Polish Office of Electronic Communications (UKE), which oversees the national numbering plan in accordance with ITU-T E.164 recommendations.
Dialing Formats and Instructions
For callers within Poland, the local format is 22 XXX XX XX (8 digits after the trunk prefix). When dialing from a Polish mobile or landline, you must include the trunk prefix 0 before the area code: 0-22 XXX XX XX. For international callers, the format is +48 22 XXX XX XX (drop the leading 0). Example: A Warsaw landline number might be +48 22 123 45 67.
Since 2005, Poland uses closed dialing plan, meaning that the trunk prefix '0' is only used for domestic calls, and the area code is always required even for local calls. There are no overlay codes in Warsaw; the 22 code is the sole geographic code for the capital, and no additional area codes have been introduced.
Caller Instructions
- Local callers (within Warsaw): Dial the 8-digit subscriber number directly (e.g., 123 45 67).
- National callers (outside Warsaw): Dial 0, then 22, then the 8-digit number (e.g., 0-22 123 45 67).
- International callers: Dial your country's exit code, then 48, then 22, then the 8-digit number (e.g., from the US: 011 48 22 123 45 67).
When dialing from a mobile phone in Poland, you can use either the full national format (0-22...) or the international format (+48 22...), as both are supported.
Numbering and Routing Considerations
Numbers with the 22 prefix are 9 digits long in international format (including the country code but excluding the leading zero). The subscriber number length is fixed at 8 digits. Geographic numbers are often used by businesses and residents, and they are not subject to mobile number portability (MNP) between geographic and mobile codes. However, fixed-line numbers can be ported between operators within the same geographic area, but the geographic significance remains.
For VoIP services, users may obtain a 22 number to establish a virtual presence in Warsaw, but the service is still considered geographic and subject to the same dialing rules.
