📍 Geographic Location of Lima/Callao

Geographic Coverage and Administrative Jurisdiction

The country calling code +51 is assigned to Peru, and the national destination code (NDC) 1 designates a geographic area covering the Lima Metropolitan Area and the Constitutional Province of Callao. This includes the capital city of Lima, the surrounding districts, and the port city of Callao. The area is the political, economic, and cultural heart of Peru, hosting the national government, major financial institutions, and the primary international airport (Jorge Chávez International Airport).

Dialing Formats and Number Structure

Peruvian geographic numbers, including those in Lima/Callao, consist of eight digits after the country code and area code. The national significant number (NSN) is therefore 9 digits long: the area code (1) followed by an 8-digit subscriber number. When dialing locally within Lima/Callao, the area code is often omitted, and callers dial only the 8-digit subscriber number. However, for calls from other regions in Peru, the full national format is required: 0-1-XXXX XXXX. Internationally, callers must use +51 1 XXXX XXXX, dropping the leading trunk prefix '0'. For example, a local number might be 1234 5678; from abroad, it would be +51 1 1234 5678.

Overlays and Numbering Evolution

Peru's numbering plan has undergone changes to accommodate growth. In 2008, the country migrated to a closed numbering plan for mobile services, but geographic numbers retained their structure. Lima/Callao has not implemented overlay area codes; the area code 1 remains exclusive to this region. However, due to the high demand for numbers, the regulatory body (OSIPTEL) has implemented number pooling and other measures to ensure efficient use of the existing 8-digit subscriber number range.

Caller Instructions

  • Local callers (within Lima/Callao): Dial only the 8-digit subscriber number (e.g., 1234 5678).
  • National callers (from other Peruvian regions): Dial 0-1-XXXX XXXX (trunk prefix 0, area code 1, then the 8-digit number).
  • International callers: Dial +51 1 XXXX XXXX (country code 51, area code 1, then the 8-digit number).

When dialing from a mobile phone within Peru, it is recommended to use the full national format (0-1-XXXX XXXX) to avoid ambiguity, especially when using VoIP services or when the call may be routed through different networks.
