📍 Geographic Location of Arica, Arica and Parinacota
Geographic Coverage and Administrative Jurisdiction
The country calling code +56 belongs to Chile, and the national destination code (NDC) 58 designates a specific geographic area within the country. Specifically, prefix 58 is assigned to the Arica and Parinacota Region, located in the far north of Chile. This region encompasses the provinces of Arica and Parinacota, with the city of Arica serving as the regional capital and the primary urban center. The code covers the entire region, including smaller towns and rural localities such as Putre, General Lagos, and the surrounding valleys and altiplano areas. As a geographic code, it is tied to the PSTN (Public Switched Telephone Network) and is used for fixed-line services within this jurisdiction.
Dialing Formats and Caller Instructions
For callers within Chile, dialing a fixed-line number in the Arica region requires the trunk prefix 0 followed by the area code 58 and the subscriber number. The subscriber number typically consists of 6 digits, making the total national significant number (NSN) 8 digits (58 + 6 digits). For example, a local number might be 58 2 345678. When calling from abroad, the international prefix (00 or +) is used, followed by the country code 56, the area code 58 (without the leading trunk prefix), and the subscriber number. Thus, an international caller would dial +56 58 2 345678. It is important to note that the trunk prefix 0 is only used for domestic calls within Chile and must be omitted when dialing from outside the country.
Overlay and Numbering Plan Considerations
As of the current numbering plan, there is no overlay code for the Arica region; the 58 code is exclusive to this geographic area. However, users should be aware that number portability allows subscribers to retain their fixed-line numbers when changing service providers within the same geographic area. Additionally, with the growth of VoIP and mobile services, calls to geographic numbers are increasingly routed over IP networks, but the dialing format remains unchanged. For callers within the region, local calls may be dialed using only the subscriber number in some cases, but the recommended format for clarity is the full national format including the area code.
Practical Examples and Usage
To illustrate, consider a business in Arica with the subscriber number 2 345678. A caller from Santiago, Chile, would dial 0 58 2 345678. A caller from the United States would dial +56 58 2 345678. It is essential for international callers to replace the trunk prefix with the + sign and country code. This ensures proper routing through international gateways. For any assistance, users can refer to their local telecom provider or international dialing guides.
