BASIC TECHNICAL PLAN:
NATIONAL NUMBERING PLAN
OBJECTIVES
The objective of this National Numbering Plan (NNP) is to provide a basis for the appropriate use and administration of numbering as a limited national resource for the benefit of telecommunication service providers and users. The guiding principles of the plan consist in the rational and non-discriminatory assignment of available resources in conformity with the regulations in force. It is essential for the numbering to be easy to understand and used by users, and to provide them with guidance on the prices of calls.
3 STRUCTURE OF NATIONAL NUMBER

6 MIGRATION PROCESS
6.1 Dissemination
The changes to be effected as part of this transition must be disseminated fully in order to explain the rationale and basis thereof and in order to allow users to assimilate the new NNP.
6.2 Detailed programme of changes
6.2.1 Migration of geographic numbers – fixed telephony
– Migration to 8 digits:
Region | Locality | Existing subscriber number | New subscriber number |
MMA | Pocitos | 2-7079321 | 2-7079321 |
East | Maldonado | 42-114000 | 4-2114000 |
East | Aiguá | 446-2000 | 4-4462000 |
Central South | Canelones | 33-11820 | 4-3311820 |
Coastal South | Cardona | 536-7000 | 4-5367000 |
North | Rivera | 62-20000 | 4-6220000 |
North | Quebracho
Ruralcel | 7504-000 | 4-7504000 |
Parallel running: International long-distance providers will be required to allow access to international calls dialled using the former numbering for a year following migration and to effect all the transfers required to hand them over to another network within Uruguay.
6.2.2 Migration of services not complying with this NNP
Providers will have up until the date of migration to relocate the services and numbers to comply with this NNP. URSEC may authorize exceptional periods of parallel running in order to resolve specific technical problems.
6.2.3 Migration of services in non-geographic numbering plans
Non-geographic numbering will be national and will therefore have to be accessible from anywhere in Uruguay and from any network using the same numbering. Customers contracting non-geographic numbers will be able to restrict or select the sources from which they wish to receive calls.
6.2.4 Use of prefixes for international long-distance provider selection
Once the relevant notification has been received from the Unidad Reguladora de Servicios de Comunicaciones (URSEC), local service providers (fixed and mobile) will have six months in which to make it possible to select the international long-distance provider by dialling.
6.2.5 National number dialling
At the request of providers, URSEC may authorize national number dialling without the need to dial the prefix 0.
