Number Portability (+ e-Portability)

Providers of publicly available telephone services, including those operating mobile electronic communications networks, are required to enable their subscribers, upon request, to retain their assigned number regardless of a change in operator. This applies for geographic numbers: at a specific location, for non-geographic numbers (i.e. mobile network numbers): at any location.The obligation of operators to enable number portability does not apply in cases where the subscriber changes geographic location, nor does it apply to the transfer of numbers from a fixed electronic communications network to a mobile network, or vice versa.

The subscriber shall submit a number portability request to the recipient operator (the operator to whose network the number is being transferred), using the prescribed form for number portability in a mobile network or for number portability in a fixed network, as applicable.

The recipient operator of the user requesting number portability must provide timely information about the number portability procedure, particularly regarding: 

• The period during which the service will be unavailable (porting timeframe),
• The loss of services previously used in the donor operator’s network after the number has been ported,
• The scope and activation of services with the recipient operator,
• The procedure for settling any outstanding debts with the donor operator,
• The reasons for potential rejection of the portability request,
• The reasons for any delay in number transfer,
• The time limit after which a user may submit a new portability request,
• The conditions under which number portability is carried out.

Upon receipt of the user's portability request, the recipient operator immediately submits a portability request to the donor operator. This submission is considered the user's final request to terminate the subscriber relationship with the donor operator and constitutes a request for the termination of all services provided by the donor operator.

Advice on how to change your operator while keeping your number can be found under the Advice for Users section. Instructions for submitting a request, as well as the option to check the status of your request online or verify which network a user belongs to, are available in the e-Agency section.
