Peru's new international phone numbers

As of this weekend, international callers phoning mobile numbers in Peru will have to contend with a battery of new digits. The government ordered a new system of numbers to handle the rapid growth in mobile phones in the country.

The new numbering system will more than double the number of available mobile numbers to more than 60 million. Land line numbers will not be affected.

• Lima and Callao mobile phone numbers already feature an additional nine and the current change simply requires an additional one before the number called.
• Mobile phones in Arequipa, La Libertad, Lambayeque and Piura will require a brand new code prior to the phone number being dialed. This three-digit number is in addition to the region code already required for calls.
• For all other departments, the new numbers will be a nine in front of the existing department code. This three-digit number will follow the existing department code when dialing.
