Further information about number portability
Number portability in Denmark was introduced in two phases.
The first phase took effect from 15 October 1999, when it became possible for end-users to retain their subscriber numbers when changing between providers within the areas of telephony and ISDN, provided that there was no relocation at the same time beyond the geographical area that belongs under the exchange to which the end-user was connected.
The second phase is divided into two stages:
- On 1 January 2001, end-users got the option of retaining their subscriber numbers when changing between providers within the areas of telephony and ISDN.
- On 1 July 2001, end-users got the option of retaining their subscriber numbers when changing between providers within the area of public mobile communications.
Until December 2005, it was planned to provide facilities for
retaining subscriber numbers across fixed and mobile networks (known as
cross-portability). This should be seen in the light of a statutory
requirement existing since 1999 for cross-portability to be introduced.
However, the Minister for Science, Technology and Innovation has had to
postpone the introduction of cross-portability several times since
great technical problems have been encountered in establishing the
In 2005, the National IT and Telecom Agency commissioned a report examining the situation in this area in further detail. The report recommended to abolish the requirement for cross-portability, seeing that if cross-portability of numbers were to be enabled, this would result in a lower service level for end-users. Following this report and the National IT and Telecom Agency's recommendation to the Minister for Science, Technology and Innovation, the Minister proposed by Bill No. L97 that the requirement for cross-portability should be abolished as the underlying technical conditions are not present at the moment.
The Bill was passed by the Danish Parliament (the Folketing), and consequently the requirement for cross-portability has now been left out from the Act.
However, the Minister for Science, Technology and Innovation is following developments in this area and will make an assessment before the end of 2008 as to whether it might be possible to introduce cross-portability at a later date - possibly in a new form.
