Area Code 5325 – Ovalle, Coquimbo

Geographic Context and Numbering Administration

Area code 5325 is a geographic National Destination Code (NDC) assigned within the Chilean national numbering plan, administered under the technical oversight of the Subsecretaría de Telecomunicaciones (SUBTEL). This code corresponds to the urban and peri-urban zones of Ovalle, the capital of the Limarí Province, located in the Coquimbo Region of north-central Chile. The service area encompasses Ovalle’s city center and its immediate surroundings, including sectors such as La Chimba, Peña Blanca, and the agricultural valleys that depend on the Limarí River. As a geographic code, 5325 is tied to the PSTN infrastructure, including legacy copper lines, modern fiber-to-the-home deployments, and fixed wireless loops that are registered to a physical address within the exchange area.

Dialing Formats and Call Routing

For callers within Chile, reaching a subscriber in Ovalle requires the national trunk prefix 0, followed by the NDC 5325 and the subscriber’s 5-digit local number. The complete national format is 0 5325 XXX XX, where the total number of digits after the trunk prefix is 9. For example, a local number such as 2 3456 would be dialed as 0 5325 23456 from any other region in Chile. International callers must replace the trunk prefix with the Chilean country code +56, omitting the leading zero. Thus, the same subscriber would be reached by dialing +56 5325 23456 from abroad. Within the 5325 area itself, local calls may be placed using only the 5-digit subscriber number, depending on the operator’s dialing plan; however, for clarity and consistency, it is recommended to use the full national format even for on-net calls.

Regulatory and Operational Considerations

Chile implemented number portability for fixed and mobile services, which means that a subscriber’s number may not necessarily reflect the physical location of the line. While 5325 is geographically assigned to Ovalle, a ported number could be served by an exchange outside the traditional area. Nevertheless, the tariff for calls to 5325 is determined by the called party’s location, not by the ported destination, and operators must route calls based on the NDC. For businesses, having a 5325 number reinforces a local presence in Ovalle, which is particularly valuable for enterprises in agriculture, mining services, and retail that operate in the Limarí Valley. When deploying VoIP or SIP trunking, ensure that your provider supports Chilean geographic numbering and can deliver calls to the PSTN with correct caller ID presentation. For emergency services, all fixed lines in the 5325 area are routed to the appropriate local public safety answering point.
