Area Code 47 – Loja/El Oro/Zamora Chinchipe

Overview of Ecuador Area Code 47

Area code 47 is a geographic National Destination Code (NDC) assigned to the southern region of Ecuador, covering the provinces of Loja, El Oro, and Zamora Chinchipe. This area code is used for fixed-line (PSTN) services within this zone. The region is characterized by a mix of urban centers, such as the city of Loja (the capital of Loja Province) and Machala (the capital of El Oro Province), as well as rural and Amazonian areas in Zamora Chinchipe.

Geographic Coverage and Administrative Jurisdiction

The 47 code serves a diverse geographic area that spans from the Pacific coastal lowlands of El Oro to the highlands of Loja and the eastern Amazonian slopes of Zamora Chinchipe. Key cities and towns within this code include Loja, Machala, Pasaje, Santa Rosa, and Zamora. The administrative jurisdiction corresponds to the respective provincial governments, but the numbering plan is managed nationally by the Agencia de Regulación y Control de las Telecomunicaciones (ARCOTEL), which follows ITU-T E.164 recommendations.

Dialing Formats and Caller Instructions

For local callers within the same area code, the national significant number (NSN) is typically 7 digits, and local calls are placed by dialing the 7-digit subscriber number directly (without the area code). For calls from other provinces within Ecuador, callers must dial the national trunk prefix 0, followed by the area code 47, and then the 7-digit subscriber number. For example, to call a fixed line in Loja from Quito, you would dial: 0 47 XXX XXXX.

For international callers, the format is: +593 47 XXX XXXX (or +593 47XXXXXX when the subscriber number is written as a continuous string). The plus sign (+) represents the international access code, and 593 is the country calling code for Ecuador. It is important to note that the leading '0' of the national trunk prefix is omitted when dialing from abroad.

Overlay and Numbering Considerations

Currently, there is no overlay code for area 47; the code is exclusive to the region. However, number portability is available in Ecuador, allowing subscribers to retain their numbers when changing service providers within the same geographic area. The number length for fixed lines in this area is 7 digits after the area code, making the total international dialing length 11 digits (including the country code).

Practical Examples

• Local call (within Loja): XXX XXXX
• National call (from Guayaquil): 0 47 XXX XXXX
• International call (from the USA): +593 47 XXX XXXX

Understanding these dialing procedures ensures seamless connectivity for both residents and international callers reaching businesses, government offices, and residential lines in the southern region of Ecuador.
