Telephone numbers in Peru

From Wikipedia, the free encyclopedia

[[]]Most area codes in Peru changed on 1 March 2003, providing an area code for each region (national subdivision).

Peruvian area codes are 2 digits long except for Lima (area code 1).

Also on that date, '9' was prepended to existing mobile numbers. Mobile subscriber numbers are now 8 digits in Lima* (+51 1 9xxx xxxx) and 7 digits elsewhere (+51 xx 9xx xxxx).


[edit] The new mobile numbers system

The mobile numbers will change from April 5, 2008 because of the rapid increase of the mobile net in Peru. In the new number system all the cell numbers will have 9 digits (in the old system were used 8 digits for Lima, and 7 digits for the rest of regions). The change will be:


In Lima: You have to prepend 9 to your old 8 digit mobile number. (01) yxxxxxxx becomes (01) 9yxxxxxxx

In Arequipa, La Libertad, Lambayeque and Piura regions: You have to prepend the next codes to your old 7 digit mobile number:

  • In Arequipa prepend 95 [(054) xxxxxxx becomes (054) 95xxxxxxx]
  • In La Libertad prepend 94 [(044) xxxxxxx becomes (044) 94xxxxxxx]
  • In Lambayeque prepend 97 [(074) xxxxxxx becomes (074) 97xxxxxxx] and
  • In Piura prepend 96 [(073) xxxxxxx becomes (073) 96xxxxxxx]


In the rest of the regions you have to change the 9 of your old 7 digit mobile number into a 3 digit code (9 + regional code):
