Area Code 536 – Ovalle, Coquimbo

Geographic Coverage and Administrative Jurisdiction

The area code 536 is a geographic National Destination Code (NDC) assigned to the province of Limari in the Coquimbo Region of Chile. Its primary service area is the city of Ovalle, the provincial capital, along with surrounding towns and rural localities such as Monte Patria, Combarbala, and Punitaqui. The code is administered under the national numbering plan overseen by the Subsecretaria de Telecomunicaciones (SUBTEL), following ITU-T E.164 standards.

Dialing Formats

When calling a fixed-line number in Ovalle from within Chile, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The local number length is typically 7 digits, resulting in a total national significant number of 9 digits (excluding the trunk prefix). For example, a local number might be dialed as 0 536 2 123 456.

From abroad, callers must use the international prefix (e.g., 00 or +), followed by Chile's country code 56, the area code 536, and the subscriber number, without the trunk prefix. Thus, the same number would be dialed as +56 536 2 123 456.

Local and International Caller Instructions

For callers within Ovalle, local calls can often be made using only the 7-digit subscriber number, depending on the specific carrier and whether number portability applies. However, for clarity and to avoid misdialing, it is recommended to include the area code even for local calls. For callers from other regions of Chile, the full national format 0 536 [subscriber number] is required. International callers must replace the trunk prefix with the country code, resulting in +56 536 [subscriber number].

Overlay and Numbering Considerations

As of the latest SUBTEL updates, there is no overlay code for the 536 area; it remains a standalone geographic code. However, number portability allows subscribers to retain their numbers when switching between fixed-line operators, which may affect routing but not the dialing format. The code is exclusively for fixed-line services; mobile numbers in the region use distinct non-geographic prefixes (e.g., 9x).

Practical Examples

• Local call (within Ovalle): 2 123 456
• National call (from Santiago): 0 536 2 123 456
• International call (from the USA): +56 536 2 123 456

Understanding these formats ensures seamless connectivity with businesses and residents in the Ovalle area, whether for personal, commercial, or emergency purposes.
