Area Code 46 – Cavite

Overview of Area Code +63 46

Area code 46 is a geographic National Destination Code (NDC) assigned to the province of Cavite in the Philippines. It is part of the country's open dialing plan under ITU-T E.164, where the full international number format is +63 46 XXX XXXX for landline subscribers. Cavite is a densely populated province in the CALABARZON region, adjacent to Metro Manila, and is a major economic hub with numerous residential, commercial, and industrial zones.

Geographic Coverage and Jurisdiction

The code covers the entire province of Cavite, including its administrative capital, Trece Martires City, and other key cities and municipalities such as Dasmariñas, Bacoor, Imus, General Trias, Tagaytay City, and Cavite City. The NDC is administered by the National Telecommunications Commission (NTC) of the Philippines and is assigned to local exchange carriers operating in the province, including PLDT, Globe Telecom, and other local providers.

Dialing Formats

For local calls within the same area code, subscribers typically dial the 7-digit subscriber number (e.g., XXX XXXX). For calls from other landline areas in the Philippines, the trunk prefix 0 must be dialed followed by the area code and subscriber number: 0 46 XXX XXXX. International callers must dial the Philippines country code +63, then the area code without the leading zero, and the subscriber number: +63 46 XXX XXXX. For example, a landline in Dasmariñas might be reached at +63 46 123 4567.

Overlay and Numbering Considerations

As of the latest NTC assignments, there is no overlay code for Cavite; the area code 46 remains the sole geographic code for the province. However, due to the high demand for telecommunication services, the NTC has implemented number pooling and may introduce additional digit lengths in the future. Subscribers should always verify the exact number of digits when dialing, as some local numbers may have fewer than 7 digits in older exchanges, though the standard is now 7 digits.

Caller Instructions

For callers within Cavite, simply dial the 7-digit local number. For callers from other parts of the Philippines, dial 0-46-XXX XXXX. For international callers, dial +63-46-XXX XXXX. Mobile phone users in the Philippines can also dial the area code and number directly, but must include the trunk prefix 0 if calling from a mobile network (e.g., 046 XXX XXXX). It is important to note that mobile numbers in the Philippines are not tied to geographic area codes and have their own prefixes (e.g., 0917, 0905).

Economic and Demographic Context

Cavite is one of the fastest-growing provinces in the country, with a population exceeding 4 million. It hosts numerous economic zones, such as the Cavite Economic Zone (CEZ) in Rosario, and is a preferred residential location for workers in Metro Manila. The area code 46 is therefore critical for business communications, government services, and residential connectivity. The province's proximity to Metro Manila has led to significant infrastructure development, including the Cavite–Laguna Expressway (CALAX), further boosting its importance as a telecommunications hub.
