Area Code 26 – Carchi/Imbabura/Esmeraldas/Sucumbíos/Napo/Orellana

Geographic Scope and Administrative Coverage

The country calling code +593, assigned to Ecuador under ITU-T E.164, is followed by the National Destination Code (NDC) 26 for fixed-line telephone services. This NDC designates a specific geographic numbering area that encompasses the northern and eastern provinces of Ecuador, including Carchi, Imbabura, Esmeraldas, Sucumbíos, Napo, and Orellana. These provinces span from the Andean highlands to the Amazon basin, and the code serves both urban centers and rural communities within these jurisdictions.

Primary Cities and Local Dialing

Key cities within this numbering area include Ibarra (capital of Imbabura), Tulcán (Carchi), Esmeraldas (Esmeraldas), Nueva Loja (Sucumbíos), Tena (Napo), and Puerto Francisco de Orellana (Orellana). For local calls within the same NDC, subscribers typically dial the seven-digit subscriber number without the trunk prefix or area code. However, for calls originating from outside the 26 area but still within Ecuador, the national trunk prefix 0 must be dialed, followed by the area code 26 and the subscriber number, resulting in the format 0 26 XXX XXXX.

International Dialing Format

Callers from abroad must dial the international access prefix (e.g., 00 or + from most countries), followed by Ecuador's country code 593, then the area code 26 (without the leading 0), and the seven-digit subscriber number. The complete international format is +593 26 XXX XXXX. For example, a landline in Ibarra might be reached at +593 26 123 4567. It is essential to omit the trunk prefix 0 when dialing from outside Ecuador.

Numbering Plan and Overlay Considerations

Ecuador's fixed-line numbering plan uses a ten-digit national significant number (NSN) format: the NDC (two digits) plus an eight-digit subscriber number. However, within the 26 area, the subscriber number is seven digits, making the total NSN nine digits. This structure is part of the national numbering plan administered by the Agencia de Regulación y Control de las Telecomunicaciones (ARCOTEL). As of the current plan, there are no overlay codes in this region; the 26 code is exclusive to the geographic area described. Subscribers cannot port fixed-line numbers to mobile networks, but fixed-line-to-fixed-line portability exists within the same area.

Caller Instructions

For local callers within the 26 area, dial only the seven-digit subscriber number. For national long-distance calls from other fixed or mobile lines in Ecuador, dial 0, then 26, then the subscriber number. For international callers, dial your country's exit code, then 593, then 26, then the subscriber number. Always verify the subscriber number length, as some numbers may have been migrated to eight digits in specific localities; in such cases, the NDC may change. For the most accurate dialing, consult ARCOTEL's official numbering resources.
