📍 Geographic Location of Turku/Pori
Geographic Allocation and Coverage
The Finnish national destination code (NDC) 28 is a geographic area code assigned to the Turku/Pori region in southwestern Finland. This area encompasses the city of Turku (Åbo in Swedish), the regional capital of Southwest Finland (Varsinais-Suomi), as well as the historical province of Satakunta, including the city of Pori. The code covers a substantial portion of Finland's southwestern coast and inland areas, serving both urban centers and rural municipalities.
Dialing Formats and Usage
Within Finland, calls to numbers in the 28 area require the trunk prefix 0 followed by the area code and the subscriber number. For example, a local call to a subscriber number 1234567 in Turku would be dialed as 02 8123 4567 (note that the area code is often written with a leading zero for domestic use). Internationally, callers must use Finland's country calling code +358 and drop the leading zero, resulting in the format +358 28 123 4567. It is important to note that the subscriber number length within the 28 area is typically 7 digits, but some older allocations may have shorter numbers.
Overlay and Numbering Plan Considerations
Finland's numbering plan is regulated by the Finnish Transport and Communications Agency (Traficom). The 28 area code is part of the original geographic numbering scheme, and no overlay codes have been introduced for this region. However, number portability allows subscribers to retain their geographic numbers when changing operators, even if they move to a different area, which can lead to non-geographic usage of these numbers in practice. Callers should be aware that the called party may be physically located outside the Turku/Pori region despite having a 28 number.
Caller Instructions
For local callers within Finland, simply dial the 8-digit subscriber number if calling from within the same area code, or dial 02 8 followed by the subscriber number if calling from other parts of Finland. For international callers, always use the full international format: +358 28 XXX XXXX. Charges for calls to geographic numbers are typically lower than those to mobile or premium services, and many Finnish operators include such calls in domestic bundles.
