Peru is +51
A local writes 912 345 678 — the dialer below turns that into what you press.
Since 2010 every Peruvian mobile lives in a single nationwide virtual area: nine digits opening with 9, identical whether you call from Cusco or Lima, and +51 takes them unchanged. Fixed lines still use geography, with a trunk zero before area codes like 1 for Lima on domestic long distance.
Mobiles are nine digits always starting with 9, dialed the same nationwide; Lima landlines are 1 plus seven digits.
