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.
MTC assigns department code 66 to Ayacucho; domestic long-distance form is 066.
