Change to the technical manner of carrying out the number portability process

Telefon komórkowy
Since 26th June 2015 the exchange of information between service providers regarding number portability in the mobile networks shall take place via the Localisation and Information Platform with the Central Database (PLI CBD) system, managed by the President of the Office of Electronic Communications.      


The President of the Office of Electronic Communications, fulfilling the tasks provided in the telecommunication law, makes the PLI CBD platform available to the telecommunications undertakings as a tool supporting and facilitating their operations in fulfilling the subscribers’ right to retain their numbers in case of changing service provider. It shall be noted that the time limits connected to the implementation of this right are not subject to any change. What changes is merely the formula of this process, which does not influence the time in which the number is ported.
The technical change in the manner of implementing the number portability process requires great technological commitment from all the operators and service providers operating in the mobile network. In order to make it possible for the telecommunications companies to duly prepare to work in the new system the Office, in accordance with the established and communicated schedule, made the test environment available as early as on 17th April 2015, i.e. more than two months before launching the new system, in order to allow service providers to test how their systems cooperate with the new functionality of the PLI CBD system.

However, it should be taken into account that the simultaneous switching of all the data-communication systems currently used by the telecommunications for number porting in mobile networks to a new unified platform can cause temporary difficulties in porting on the side of the telecommunication companies.

In case of problems with porting phone numbers with the use of the PLI CBD system, after 26th June 2015, the information on such cases can be submitted to UKE via the electronic platform of public administration e-PUAP (, as well using the contact form ( on our website, or in a traditional form, i.e. in writing to the address of the Office.

In case of any questions or doubts that may arise please do not hesitate to contact us. You are kindly invited to contact our UKE Consumer Information Centre - hotline: 801-900-853 (cost in accordance with the rates of the telecommunications operator) or 22 534-91-74 from Monday to Friday, during office hours (8.15 A.M.- 4.15 P.M).
