Ported Number Registry

The number porting procedure is initiated by submitting a request for number porting to the receiving operator, i.e. the operator of the network to which the number is ported and whose services the subscriber (user) will be using following the completion of the number porting procedure.

This request will also be considered as a request for the annulment of the existing subscription agreement between the subscriber (user) and the donor operator, i.e. the operator relinquishing the number porting procedure and whose services have been used by the subscriber (user) until the number porting. The agreement is annulled once the number is switched off from the network of the donor operator.

The subscriber (user) may not request the transfer of any additional services provided by the donor operator.

In order to port their numbers, users who do not have a subscriber agreement (prepaid users) have to be registered. User registration involves the identification of users in accordance with the procedures of the public telecommunications operator. The registration of unregistered prepaid users may be carried out with the receiving operator by submitting the SIM card or PUK code, as well as by providing a valid ID document (ID card or passport).

Prepaid users are not entitled to any reimbursement from the donor operator for the remaining amount on their account or unused traffic.
