Based on the telecommunications Law 431/2002 (Article 5.1.f and Article 31.1), the TRA is responsible for establishing and managing the National Numbering Plan (NNP) for subscribers and service providers of telecommunication services.

After a period of consultation, the TRA issued a new National Numbering Plan (NNP). The NNP determines the numbering rules for fixed, mobile and special services as well as new services.

The proposed plan is a closed Numbering plan that has no area code. Thus a uniform dialing procedure is applied to all calls. It makes all numbers (except international numbers and short codes) have the same length, reducing potential customer confusion and simplifying the introduction of Number Portability.

The NNP was sent to the State Council and will be published in the Official Gazette soon. The actual implementation of the NNP will be announced at a later stage in coordination with the operators.
