Area Code 27 – Azuay/Cañar/Morona Santiago

Overview of Ecuador's Area Code 27

Area code 27 is a geographic National Destination Code (NDC) assigned to the southern highlands and Amazonian foothills of Ecuador. It covers the provinces of Azuay, Cañar, and Morona Santiago, with the city of Cuenca (the capital of Azuay) as its primary urban center. This region is known for its colonial heritage, the Cajas Massif, and the gateway to the Amazon basin.

Geographic Coverage and Administrative Jurisdiction

The code serves a mix of urban, peri-urban, and rural areas. In Azuay, it includes Cuenca and surrounding parishes such as Gualaceo, Paute, and Girón. In Cañar, it covers Azogues, Biblián, and Cañar city. In Morona Santiago, it reaches Macas, Sucúa, and Gualaquiza. The area is administered by the Agencia de Regulación y Control de las Telecomunicaciones (ARCOTEL), which oversees numbering resources in compliance with ITU-T E.164.

Dialing Formats and Caller Instructions

For local callers within the same NDC (i.e., within area code 27), the national significant number is typically 7 digits (e.g., 27X-XXXX). To call from another province or mobile network within Ecuador, dial the national trunk prefix 0 followed by the area code and subscriber number: 0 27 XXX XXXX. For international callers, dial the Ecuador country code +593, then the area code without the leading '0', followed by the 7-digit subscriber number: +593 27 XXX XXXX. For example, a landline in Cuenca might be reached at +593 27 234 5678.

Overlays and Numbering Plan Considerations

Ecuador has not implemented overlay codes in this region; the area code 27 remains the sole geographic code for the three provinces. However, number portability exists for fixed lines, allowing subscribers to retain their numbers when switching operators, but the geographic NDC remains tied to the original location. Mobile numbers in Ecuador are non-geographic and always begin with 9 (e.g., +593 9X XXX XXXX), so they are not affected by area code 27.

Practical Usage for Businesses and Travelers

Businesses operating in Cuenca or the surrounding provinces should list their numbers in international format (+593 27...) to avoid confusion for global clients. Travelers calling local hotels, restaurants, or government offices should use the local dialing format when within the region. For calls from abroad, ensure you drop the trunk prefix '0' and use the full country code. This code is also used for fax and legacy PSTN services, though VoIP adoption is increasing.
