Area Code 52 – Tacna

Geographic Coverage and Administrative Jurisdiction

The area code 52 is a geographic National Destination Code (NDC) assigned to the Tacna Region in southern Peru. This region is a department and its capital city is Tacna, which is the primary urban center served by this prefix. The code covers the entire province of Tacna, including the districts of Tacna, Alto de la Alianza, Ciudad Nueva, Pocollay, and Calana, as well as rural areas and smaller towns within the province. It does not include other provinces of the Tacna Region, such as Jorge Basadre or Tarata, which use different area codes.

Dialing Formats and Caller Instructions

For callers within Peru, dialing a fixed-line number in Tacna requires the national trunk prefix 0, followed by the area code 52 and the subscriber number. The subscriber number length is typically 6 digits, making the complete national significant number (NSN) 8 digits (excluding the trunk prefix). The local dialing format is: 0 52 XXX XXX. For example, a local Tacna number might be 0 52 123456.

For international callers, the Peru country code is +51. The international dialing format is: +51 52 XXX XXX. For instance, to call a Tacna landline from abroad, you would dial +51 52 123456. When dialing locally within Tacna, the area code is often omitted for calls between numbers in the same exchange, but it is always required for calls from other regions or mobile phones.

Overlay and Numbering Plan Considerations

As of the latest ITU-T E.164 national numbering plan updates, there is no overlay code for the Tacna area. The area code 52 is exclusively assigned to fixed-line services (PSTN) in this region. However, due to the increasing demand for telecommunication services, the regulatory body (OSIPTEL) periodically reviews numbering resources. It is essential for businesses and residents to ensure that their published numbers include the area code to facilitate proper routing from any network.

Practical Guidance for Callers

When calling a Tacna number from a mobile phone within Peru, it is common to include the area code even if the caller is in the same region, as mobile networks require the full NSN. For international callers, always replace the leading '0' with the country code '+51'. Be mindful of time zones: Peru operates on Peru Time (PET, UTC-5), and there is no daylight saving time, so the time difference remains constant throughout the year.
