What is number portability?
Number portability is a service dedicated to the telephony end-users’ which enables them to keep their telephone numbers, while shifting to another provider of telephone services.
Number portability is available for the following numbering categories:
- geographic number portability – any fixed telephony subscriber has the possibility to keep his/her telephone number when he/she decides to give up their subscription to the current fixed telephony provider and to subscribe to another fixed telephony provider; geographic numbers can be ported only within the same geographic area (respectively within one county or within the municipality of Bucharest and Ilfov county). The two providers, from/to which the geographic numbers are ported, must offer services within the same geographic area and have blocks of geographic numbers, allotted by LURN, in the respective geographic area;
- mobile number portability (non-geographic) – any mobile telephony subscriber has the possibility to keep his/her mobile telephone number when he/she decides to give up their subscription to the current mobile telephony provider and to subscribe to another mobile telephony provider, irrespective of the technology used for the provision of the service (2G, 3G, CDMA etc.), of the payment method (postpaid or prepaid) or the type of services provided (voice, fax, data transmission);
- portability of non-geographic numbers, other than mobile telephone numbers – this category includes location-independent numbers (037x xxx xxx type), telephone numbers for free access services (0800-type), universal access numbers (0801-, 0803-type) and universal personal numbers (0802-type), and Premium Rate services (0900-, 0903- and 0906-type); the users of such services have the possibility to keep their numbers when they request transfer from one provider of publicly available services to another, provided the initial destination of the number is maintained.
