The Superintendencia General de Electricidad y Telecomunicaciones de El Salvador (SIGET), San Salvador, presents its updated National Numbering Plan (NNP), in force since 23 November 2011 in El Salvador.
The numbering plan for the Republic of El Salvador uses the following numbering structure:
– for services provided through access networks, eight (8) digits, including the National Destination Code (NDC),
– freephone numbers and premium rate numbers use seven (7) and eleven (11) digits.
– numbers for the international long distance service through operator, use seven(7)-digit numbering.
– the three(3)-digit numbers are used for the selection code for the multicarrier system and special services.
– a 6-digit number has been assigned for the children helpline.
The number of digits used to identify the fixed or mobile subscriber terminal is eight (8) for any part of the country, using the structure (NDC) XYZ1MCDU, where:
NDC | X | Y | Z | | M | C | D | U |
National Destination Code | Millions | Hundreds of thousands | Tens of thousands | | Thousands | Hundreds | Tens | Units |
National Destination Code (NDC) | Type of network |
2 | Fixed |
6 , 7 | Mobile |
For the purposes of numbering allocation for fixed telephony, El Salvador has been divided into four geographic areas: Western, Central, Eastern and Metropolitan.
Allocation of digit X within the structure of eight-digit numbers (NDC) XYZ1MCDU for the fixed telephony service:
Digit X | Use within the structure (2) XYZ1MCDU |
0 | Not used in this structure – reserved for future use. |
1, 2 and 5 | Used for identifying the fixed telephony service in any locality within the Metropolitan area known as “Gran San Salvador”. |
3 | Used for identifying the fixed telephony service in any locality within the Central area |
4 | Used for identifying the fixed telephony service in any locality within the Western area |
6 | Used for identifying the fixed telephony service in any locality within the Eastern area |
7 | For future use in the Eastern area |
8 | For future use in the Western area |
9 | For future use in the Central area |
Allocation of digit X within the structure of eight-digit numbers (NDC) XYZ1MCDU for the mobile telephony service:
Structure (6 ,7) XYZ MCDU | Digit X |
Mobiles | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
Recommendation ITU-T E.164 provides that the maximum number of digits for subscribers in the automatic international service should be 15, excluding the international prefix.
In the interests of harmonizing and facilitating the use of dialling structures within the region towards the rest of the world, El Salvador has adopted the prefix “00” for the automatic international service, in line with Recommendation ITU-T E.164, number 11, relating to the use of international prefixes and codes.
In El Salvador, the 15 digits do not include: two digits from the international prefix and three digits from the multicarrier system code; in other words, telephone exchanges must analyse a minimum of 20 digits. To this end, the owner of the destination telephone exchange must ensure that its equipment is capable of processing the said number of digits in a single segment or, failing that, and by agreement between the parties, in a number of segments.
Digit X | Use in the structure XYZ |
0, 2, 3, 4, 5, 6, 7, 8 | Not used in this structure |
1 | a) Used for the selection keys of the multicarrier system. b) Used in special services for : – government institutions; – assistance to the population in cases of emergency or criminal acts; – humanitarian aid; – temporary arrangements to meet community needs;1 – operators’ own internal services, and c) Future services to be determined by SIGET. |
9 | Special services used by government institutions, where Y=1. |
1 Emergencies caused by natural phenomena, public disaster situations, coordination efforts for humanitarian purposes, major national or regional events, and any unforeseen and duly acknowledged situations, calling for telephone access by means of a short number. Such numbers shall be assigned for a maximum period of three months, with any request for an extension to be assessed by SIGET. |
CHILD HELPLINE Type of service | Number | Use | Children Helpline* | 116 111 | For use from any network access and from any terminal. It is a free service for users and free of interconnection charges. Enabling this service is mandatory for all operators and the government will be responsible for defining the institution providing the service. (ITU-T E.164 Supplement 5) |
* This numbering scheme will be operational six (6) months after the entry into force of this Plan. |
