Numbering Policy

Numbers have a key role for the operation of telecommunication services. Numbers provide, like frequencies, access to these services (e.g. by the identification of terminals) and facilitate the management of these services for end-users as well as providers of the services. The policy objectives of the Ministry of Economic Affairs are to safeguard the availability of sufficient and adequate numbers used for telecommunication purposes, now and in the future.

The Authority for Consumers & Markets (ACM) assigns and withdraws numbers and supervises the usage of numbers. Information on number assignments can be found in the public registers of the ACM.

Numbering plans

The type and usage of numbers are regulated in numbering plans. Numbering plans have a wide public interest and fall under the responsibility of the Ministry of Economic Affairs. Numbering plans are focused on public telecommunication infrastructures but may also address non-public telecommunication infrastructures.

1.  Telephone and ISDN Services Numbering Plan

One important numbering plan is the Telephone and ISDN Services Numbering Plan. This numbering plan comprises amongst others geographical numbers and numbers for mobile telephony, information services and Machine-to-Machine (M2M) applications. The Telephone and ISDN Services Numbering Plan (as per 1-2-2016) is attached below as the first appendix. An important change to this plan was made in 2011 to accommodate M2M applications. The concerning Decree is attached below as the first appendix.

2. Decree change of Telephone and ISDN Services Numbering Plan for M2M applications

Important change to the Telephone and ISDN Services Numbering Plan (appendix 1), this plan was made in 2011 to accommodate M2M applications. The concerning Decree is attached below as the second appendix.

3. Numbering Plan for international mobile subscription identities (IMSIs)

The Numbering Plan for international mobile subscription identities (IMSIs) is the national implementation of Recommendation E.212 of the International Telecommunication Union (ITU). This recommendation describes the structure and use of international mobile subscription identities (IMSIs). An IMSI consists of three components: a mobile country code (MCC), a mobile network code (MNC), and a mobile subscription identity number (MSIN). IMSIs are used worldwide to identify mobile network equipment and subscribers.

A national Decree taken in 2014 expands the possibilities for using MNCs, and thus also those for using IMSIs. It created broader possibilities for using MNCs in the context of the increased use of local wireless private networks as well as the increased use of mobile networks for M2M applications. The Decree makes it possible to assign MNCs to holders of non-public electronic communication networks for the purposes of wireless communication.

Decree containing amendments to the Numbering Plan for international mobile subscription identities (IMSIs) relating to the use of IMSIs by private networks (3 March 2014) is also attached below, as the third appendix.
