Area Code 41 – Amazonas

Geographic Coverage and Administrative Jurisdiction

The country calling code +51 belongs to Peru, and the national destination code (NDC) 41 designates the Amazonas region. This geographic area code covers the department of Amazonas, located in the northern highlands of Peru, bordering Ecuador. The region's capital and largest city is Chachapoyas, which is the primary hub for telecommunications within the zone. Other significant towns served by this code include Bagua Grande, Bagua, Utcubamba, and Rodríguez de Mendoza. The code is assigned to fixed-line PSTN services, and it is used for both local and national long-distance calls.

Dialing Formats and Number Structure

In Peru, the national significant number (NSN) for geographic areas is nine digits long, comprising the area code (two digits) followed by a seven-digit subscriber number. Therefore, a typical number in the Amazonas region is formatted as +51 41 XXX XXXX when dialed from abroad, or 041 XXX XXXX when dialed domestically within Peru (the leading '0' is the national trunk prefix). For local calls within the same area code, callers may dial only the seven-digit subscriber number, omitting the area code and trunk prefix. However, it is always safe to dial the full national format, as Peruvian carriers support it.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Amazonas region; the 41 code is exclusively used for this geographic area. The Peruvian numbering plan, regulated by the Ministry of Transport and Communications (MTC), has not introduced overlay codes for fixed-line services in this region. As a result, number portability is available for fixed lines, allowing subscribers to retain their numbers when changing operators within the same geographic area. However, porting a fixed-line number to a mobile network is not permitted, as mobile numbers are non-geographic and use distinct prefixes (e.g., 9XX XXX XXX).

Caller Instructions

For callers within Peru: To call a fixed line in Amazonas from another region, dial 0 41 XXX XXXX. For international callers: Dial your country's international access code (e.g., 011 from the US, 00 from many European countries), followed by Peru's country code 51, then the area code 41 and the subscriber number: +51 41 XXX XXXX. For example, a call to a business in Chachapoyas might be dialed as +51 41 478 1234 from abroad.

Practical Usage Notes

Amazonas is a primarily rural and mountainous region, and fixed-line penetration is lower than in coastal urban areas. Many residents and businesses rely on mobile services, but the 41 code remains essential for government offices, banks, and established enterprises. When contacting these entities, always verify the correct number of digits, as some older numbers may have fewer than seven digits, but the current plan standardizes on seven. For VoIP users, the same dialing rules apply, and the call will be routed to the PSTN.
