Area Code 75 – Lima

Geographic Overview

The area code 75 is a geographic National Destination Code (NDC) assigned to the Lima region in Peru. However, it is important to note that this code is not for the Lima Metropolitan Area (which uses 1), but rather for the Lima Province (also known as Lima Provincias), which encompasses the surrounding provinces and districts outside the capital city. This includes cities such as Huacho, Huaral, Cañete, and Barranca. The code covers a vast area along the central coast and into the Andean foothills, serving both urban and rural communities.

Dialing Formats

For callers within Peru, the national trunk prefix is 0, followed by the area code and the subscriber number. The subscriber number length in this region is typically 6 digits, making the total national significant number (NSN) 9 digits (including the leading 0 for domestic calls). The international format, following ITU-T E.164, omits the trunk prefix and includes the country code +51.

• Domestic call (within Peru): Dial 0 75 XXXX XX (example: 0 75 234 567).
• International call (from abroad): Dial +51 75 XXXX XX (example: +51 75 234 567).

When dialing from a mobile phone within Peru, it is common to use the international format (+51 75...) even for domestic calls, as this ensures proper routing across all networks.

Caller Instructions

For local callers: If you are physically located within the Lima Province area code 75 region, you may be able to dial just the 6-digit subscriber number for local calls, depending on your telephone operator's configuration. However, with the proliferation of mobile and VoIP services, it is recommended to always include the area code to avoid misrouting.

For international callers: Always replace the leading '0' with the country code +51. Ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries) before dialing +51 75...

Overlay and Numbering Considerations

Peru's numbering plan is administered by the Ministry of Transport and Communications (MTC) and the telecom regulator OSIPTEL. The area code 75 is a geographic code and is not overlaid with any other code; it is exclusively assigned to the Lima Province region. As of the latest updates, there are no plans for an overlay, but subscribers should be aware that number portability allows users to retain their numbers when switching operators, even across fixed and mobile services, which may affect the association of a number with a specific geographic area.

Usage and Services

The code 75 is used for fixed-line PSTN services, as well as for VoIP and fixed wireless services that are registered to the region. Businesses and residents in this area rely on this code for their local presence. When contacting services in this region, always verify the correct area code to avoid long-distance charges or misdialing.
