NTA's role and ITU numbering plan
Short answer
NTA, the independent telecom regulator, licenses operators, manages spectrum, controls tariffs, ensures fair competition, and runs the numbering plan. Under ITU E.164, numbers are structured as country code (977 for Nepal) + national destination code + subscriber number, not exceeding 15 digits. For example, a Kathmandu fixed line becomes +977 1 4412345.
Describe the role of NTA for the development of telecommunication sector in Nepal. Write a numbering plan as per ITU rules and regulation.
Role of NTA in development of the telecom sector of Nepal
The Nepal Telecommunications Authority (NTA) is the independent regulator established in 1998 under the Telecommunications Act, 2053 (1997).
- Licensing telecom operators and ISPs, opening the market to competition.
- Spectrum management: allocating and monitoring radio frequencies.
- Tariff and interconnection regulation for fair, affordable prices.
- Quality of service standards and consumer protection.
- Rural Telecommunication Development Fund for services in remote areas.
- National numbering plan management.
- Type approval, adoption of standards and policy advice to the Government.
Numbering plan as per ITU (E.164)
ITU-T Recommendation E.164 defines the international public telecommunication numbering plan. An international number has at most 15 digits (excluding the international prefix).
[Intl prefix] [CC] [NDC] [SN]
00 977 1 4412345
<---- max 15 digits ---->
- International prefix: chosen nationally; 00 is the ITU-recommended prefix (written as "+").
- CC (country code): 1–3 digits, assigned by ITU; first digit gives the world zone (9 for most of Asia; Nepal = 977).
- NDC (national destination code): area code or mobile network code.
- SN (subscriber number).
- NSN = NDC + SN; its length is set by the national regulator (NTA in Nepal).
- Trunk prefix (0 in Nepal) is used only inside the country and is dropped in international format.
| Zone | Region |
|---|---|
| 1 | North America |
| 2 | Africa |
| 3, 4 | Europe |
| 5 | Latin America |
| 6 | Oceania |
| 7 | Russia |
| 8 | East Asia, global services |
| 9 | Asia, Middle East |
Example: Kathmandu fixed line 01-4412345 is +977 1 4412345 internationally; a mobile 9841XXXXXX is +977 9841XXXXXX.
