Telephone numbers in Finland


All of Finland, including the Åland Islands, has the same country code, +358.
Finland's numbering plan was reorganised in 1996, with the number of area codes being reduced, and the trunk code being changed from 9 to 0. This meant that the area code for Helsinki also changed:
Within FinlandOutside Finland
Before 199690 xxx xxx+358 0 xxx xxx
After 199609 xxx xxx+358 9 xxx xxx

The default international access code became 00, although other prefixes such as 99 can be also used.

Mobile numbers

Finnish mobile numbers start with 04x, 0457 or 050. The format for mobile telephone numbers is 04x 123 45 67 or 0457 123 45 67 or 050 123 45 67. When called from a different country, the format is + 358 4x 123 45 67 or + 358 50 123 45 67. Most commonly 7 digits are used for subscriber number, with normal range being from 4 to 8 digits.
The first three digits previously indicated the mobile operator but mobile number portability has been implemented and any prefix can now be associated with any operator, 040 and 050 are most common prefixes. 042 and 045 0 were also owned by TeliaSonera, whereas 046 was owned by Elisa. Other major networks are DNA Finland and Saunalahti. Former operator codes include 043, which was used in DCS "city phones". Some of these may still be in use. The former NMT network numbers used operator code 049. Most NMT numbers were transferred to GSM numbers with format 04x0 123 456 or 0500 123 456, as there were only 6 subscriber numbers in NMT numbers.
The area code for fixed landline subscriptions in Kymi is 05, and should not be confused with mobile numbers starting with 050.
