Area Code 84 – Cusco

Geographic Overview

The area code 84 is the National Destination Code (NDC) assigned to the department of Cusco in Peru. This geographic code covers the city of Cusco (the historical capital of the Inca Empire) and its surrounding provinces, including Anta, Calca, Urubamba, and Quispicanchi. As a geographic allocation, the code is tied to the PSTN infrastructure of the region, serving both fixed-line residential and business subscribers.

Dialing Formats

When calling a fixed-line number in Cusco from within Peru, the national trunk prefix 0 is used, followed by the area code and the subscriber number. The local subscriber number typically consists of 6 to 7 digits, resulting in a total national significant number length of 8 to 9 digits (excluding the trunk prefix). For example, a local number might be dialed as:

• National format: 0 84 XXX XXXX (or 0 84 XXX XXX for 6-digit numbers)
• International format: +51 84 XXX XXXX (or +51 84 XXX XXX)

For instance, a typical Cusco landline number could be +51 84 234567 (7-digit subscriber number) or +51 84 23456 (6-digit subscriber number). Always verify the exact number of digits with your contact.

Calling Instructions

For callers within Peru: Dial the trunk prefix 0, then the area code 84, followed by the local subscriber number. Example: 0 84 234567.

For callers from abroad: Dial the international access prefix (e.g., 00 from most countries, or +), then the country code 51, the area code 84 (without the leading 0), and the subscriber number. Example: +51 84 234567.

Overlay and Numbering Considerations

Currently, there is no overlay code for Cusco; the area code 84 is unique to this geographic region. However, due to the growth of fixed-line services and the migration to VoIP, some numbers may be routed over IP networks, but they retain the geographic identity. When dialing from a mobile phone within Peru, it is common to include the area code even for local calls, as mobile networks require the full national number.

Important Notes

As with all geographic codes in Peru, the cost of a call to a Cusco number depends on the caller's location and the type of network (fixed or mobile). Calls from mobile phones may incur higher tariffs. Always check with your service provider for applicable rates.
