Area Code 615 – Baja California Sur

Geographic Coverage and Administrative Jurisdiction

Area code 615 is a geographic National Destination Code (NDC) assigned to the state of Baja California Sur, Mexico. It serves the central and southern portions of the state, including the municipalities of La Paz (the state capital), Los Cabos (which includes the tourist hubs of San José del Cabo and Cabo San Lucas), and Comondú (including Ciudad Constitución). The code also covers smaller communities such as Todos Santos, El Pescadero, and Santiago. As part of the Mexican numbering plan, the 615 prefix is used for fixed-line (PSTN) and some VoIP services, but it is not assigned to mobile numbers, which use the national mobile code 1 (e.g., +52 1 615...).

Dialing Formats and Caller Instructions

For local calls within the 615 area, dial the seven-digit local number directly (e.g., 612 123-4567). For calls from other area codes within Mexico, dial the long-distance prefix 01 followed by the area code and local number: 01 615 612 1234. For international callers, dial the Mexican country code +52, then the area code 615, and the seven-digit local number: +52 615 612 1234. When calling from a mobile phone in Mexico, it is common to omit the 01 prefix, but for landline-to-landline calls, the 01 prefix is still required. Visitors to Baja California Sur should note that while the region is popular with tourists, the 615 area code is not toll-free; standard long-distance charges apply when calling from outside the area.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 updates for Mexico, area code 615 does not have an overlay. The state of Baja California Sur is served by two geographic area codes: 612 for the northern part (including Loreto and Mulegé) and 615 for the south. This division ensures that local numbers remain seven digits long, and no changes to dialing patterns are anticipated in the near future. However, due to the growth of VoIP and the increasing demand for numbers in tourist areas, the Federal Telecommunications Institute (IFT) may introduce overlays or new area codes in the future. For now, callers should always use the full 10-digit number (area code + local number) when dialing from outside the local area, as this is the standard for the Mexican numbering plan.

Practical Examples for Callers

• Local call within La Paz: Dial 612 1234 (seven digits).
• From Mexico City (area code 55) to La Paz: Dial 01 615 612 1234.
• From the United States to Cabo San Lucas: Dial 011 52 615 612 1234 (or +52 615 612 1234 on mobile).
• From a Mexican mobile phone to a 615 landline: Dial 01 615 612 1234 (or simply 615 612 1234 if your carrier supports it).

When dialing internationally, always replace the trunk prefix '0' with the country code +52. This ensures proper routing through the PSTN. For businesses in Baja California Sur, having a 615 number signals a local presence and can be reached by customers worldwide using the standard international format.
