History
Peru approved its Fundamental Technical Numbering Plan in 2002. The present department-code structure took effect on 1 March 2003. On 4 September 2010, the Virtual Mobile Area made mobile numbering nationwide and non-geographic, so international callers now dial +51 followed directly by the nine-digit mobile number without a department code.
Code 1 is the only one-digit Peruvian geographic code; its domestic long-distance form is 01.

Network interpretation
Largest Telephone Carriers
Current operator and market-share data are dynamic. This page avoids assigning a specific number to a carrier from its area code alone.
Landline
Area code 01 is presented as a geographic fixed-line identifier. Consult Ministerio de Transportes y Comunicaciones (MTC) for current allocation or licensing information.
Wireless
Wireless numbers commonly use separate ranges. Number portability prevents reliable current-carrier identification from a prefix alone.
