Area Code 612 – La Paz/Todos Santos, BCS

Geographic Coverage and Regulatory Context

Country code +52 corresponds to Mexico. The area code 612 is a geographic National Destination Code (NDC) assigned to the southern portion of the state of Baja California Sur (BCS). Specifically, it serves the state capital La Paz and the surrounding municipalities, including the coastal town of Todos Santos, as well as nearby localities such as El Centenario, San Pedro, and the agricultural areas of El Carrizal. This code is administered by the Instituto Federal de Telecomunicaciones (IFT) and is allocated to fixed-line PSTN services, although some mobile numbers may also be ported into this geographic range.

Dialing Formats and Number Structure

In the Mexican national numbering plan, numbers under area code 612 have a total length of 10 digits when dialed nationally, excluding the trunk prefix '0'. The format is: 0 612 XXX XXXX (national long-distance) or simply 612 XXX XXXX when dialed from a local line within the same area code. For international callers, the full E.164 format is +52 612 XXX XXXX, where the leading '+' replaces the international access code (e.g., 011 from the US/Canada).

Local Dialing and Overlay Considerations

Within the 612 region, local calls can be made using the 8-digit subscriber number (XXX XXXX) without dialing the area code. However, due to number exhaustion and the introduction of overlay codes in some Mexican cities, it is always advisable to confirm with your local provider. As of now, 612 does not have an overlay, but users should be aware that mobile numbers in the area may be assigned to any Mexican carrier and can be ported, so the prefix does not guarantee a specific operator.

Caller Instructions

For callers within Mexico: To call a 612 number from another area code, dial the long-distance prefix '0', then the area code 612, followed by the 7-digit local number. For example, to call a La Paz number from Mexico City, dial 0 612 XXX XXXX.

For international callers: Dial your country's international exit code (e.g., 011 from the US), then Mexico's country code 52, then the area code 612, and the 7-digit subscriber number. Example from the US: 011 52 612 XXX XXXX or using the '+' notation: +52 612 XXX XXXX.

Commercial and Tourism Relevance

La Paz is a major commercial and tourism hub, known for its waterfront, ecotourism, and as a gateway to the Sea of Cortez. Todos Santos is a popular tourist destination with a growing community of expatriates and artists. Businesses in these areas rely on 612 numbers for local customer service, and many hotels, tour operators, and government offices use this code. When contacting such services from abroad, always use the international format to ensure proper routing.
