📍 Geographic Location of Lódź
Geographic Overview
The +48 42 country and area code combination is the international dialing prefix for the city of Łódź and its immediate metropolitan area in central Poland. As a geographic number, it is assigned under Poland's National Numbering Plan, administered by the Office of Electronic Communications (UKE). The code covers the capital of the Łódź Voivodeship, including districts such as Polesie, Widzew, Śródmieście, and Bałuty, as well as adjacent municipalities like Pabianice, Zgierz, and Konstantynów Łódzki. Subscribers within this region share the 42 prefix, which is a National Destination Code (NDC) in E.164 format.
Dialing Formats
When calling a Łódź landline from abroad, dial the international access prefix (e.g., 00 from most countries, or + from mobile), followed by Poland's country code 48, then the area code 42 (without the leading trunk prefix '0'), and finally the 7-digit subscriber number. For example, a local number 1234567 would be dialed as +48 42 1234567 from outside Poland. Within Poland, callers must use the trunk prefix '0' before the area code: 0 42 1234567. For local calls within the Łódź area, the area code may be omitted, allowing direct dialing of the 7-digit number, though this practice is becoming less common with the rise of mobile and VoIP services.
Numbering and Overlays
Łódź numbers are 9 digits long when including the country code (or 8 digits nationally, including the area code). The area code 42 is a geographic code, meaning it is tied to a physical location, but number portability allows subscribers to retain their number when moving to a different operator. There is no overlay code in Łódź; the 42 prefix is exclusive to this region. However, due to the exhaustion of available numbers, UKE has implemented measures to optimize number allocation, but no overlay has been introduced as of 2024.
Caller Instructions
For international callers, always replace the leading '0' of the national trunk prefix with '+48' when dialing from a mobile phone. For example, to call a Łódź number 7654321, dial +48 42 7654321. If you are in Poland and calling from a mobile phone, you can also use the +48 format. For landline callers within Poland, remember to include the '0' trunk prefix before the area code when calling from outside the Łódź region. Calls to Łódź numbers are typically charged at standard national or international rates, depending on your carrier and plan.
