Area Code 533 – Ovalle, Coquimbo

Geographic Coverage and Administrative Jurisdiction

Area code 533 is a geographic National Destination Code (NDC) assigned to the province of Limari in the Coquimbo Region of Chile. The primary city served by this code is Ovalle, the provincial capital, along with surrounding localities such as Combarbala, Monte Patria, Punitaqui, and Rio Hurtado. These areas fall under the jurisdiction of the Chilean telecommunications regulator, the Subsecretaria de Telecomunicaciones (SUBTEL), which oversees the national numbering plan in accordance with ITU-T E.164 recommendations.

Dialing Formats and Caller Instructions

For callers within Chile, the local dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a fixed line in Ovalle, you would dial:

• 0 533 2 123456 (domestic call)

International callers must use Chile's country code +56, followed by the area code without the leading trunk prefix. The same number dialed from abroad would be:

• +56 533 2 123456 (international call)

Note that the subscriber number in this area typically consists of 6 to 7 digits, and the total length of a national significant number (NSN) is 8 to 9 digits, including the area code.

Overlay and Numbering Considerations

Currently, area code 533 does not have an overlay code; it is the sole geographic code for the Limari province. However, as part of Chile's ongoing numbering plan evolution, SUBTEL has implemented measures to ensure number portability and efficient use of resources. Fixed-line numbers in this region are primarily used for PSTN and VoIP services, and they are not portable to mobile networks, which use separate non-geographic codes (e.g., 9x). Callers should always verify the correct area code when dialing, as misdialing may route calls to other regions in Chile.

Practical Information for Local and Foreign Callers

When calling from a mobile phone within Chile, it is common to include the trunk prefix even for domestic calls, as mobile networks require the full national number. For foreign callers, it is essential to replace the leading zero with the +56 country code. Additionally, be aware of time zone differences: Chile uses Chile Standard Time (CLT, UTC-3) and observes daylight saving time, so adjust your calling schedule accordingly.
