40 Chapter 14 Numbering Section 98 Telecommunications areas The division of Finland into telecommunications areas is decided by Ficora. The division into telecommunications areas shall be appropriate. In establishing telecommunications areas, special attention shall be paid to the amount of telecommunications in different localities and its orientation, the technical structure of communications networks and the most efficient use of numbers. Section 99 Finnish Communications Regulatory Authority numbering regulations Numbers and identifiers shall be distributed taking into account: 1) clarity and efficiency of numbering; and 2) international obligations regarding numbers and identifiers. Ficora may issue further regulations on numbering. Ficora may order the type of numbers and identifiers that may be used in telecommunications and the purpose for which they are to be used. A Finnish Communications Regulatory Authority regulation on numbering may also specify the geographical area of use for the numbers and identifiers. Separate provisions shall be issued on Internet domain names. Section 100 Numbering decisions The numbers and identifiers to be issued for the use of telecommunications operators and other persons are decided by Ficora. Numbers and identifiers shall be distributed in a manner that treats telecommunications operators and other persons as fairly as possible taking into account the nature and extent of operations. Ficora shall decide on the issuing of a number or identifier (numbering decision) within three weeks of receipt of an application. However, if a number or identifier is of exceptional economic value, the numbering decision may be made within six weeks of receipt of the application. In a numbering decision, the holder of the right to use a number or identifier may be required to start using the number within a reasonable time. A numbering decision may remain in force until further notice or for a fixed period appropriate to the service being provided. In a numbering decision, Ficora may order that the number be used to offer a specified service and it may impose other conditions on the use of the number necessary to ensure the clarity and efficiency of numbering or the benefits of users.
