Area Code 4279 – Quezon

Overview of Area Code 4279

Area code 4279 is a geographic National Destination Code (NDC) assigned to the province of Quezon in the Philippines. It forms part of the country's open dialing plan, where the trunk prefix '0' is used for domestic calls and the international access code '+63' replaces the leading zero for calls originating outside the Philippines. The code serves the entire province, including its capital, Lucena City, and other major municipalities such as Tayabas, Sariaya, and Candelaria.

Geographic Coverage and Administrative Jurisdiction

Quezon is located in the CALABARZON region on Luzon Island. The area code 4279 is allocated to the province's Public Switched Telephone Network (PSTN) infrastructure, covering both fixed-line and some fixed-wireless services. The National Telecommunications Commission (NTC) of the Philippines oversees the assignment and management of numbering resources, ensuring that geographic codes like 4279 correspond to specific rate centers within the province.

Dialing Formats and Caller Instructions

• Local calls within Quezon: Dial the 7-digit subscriber number directly (e.g., 234-5678).
• Domestic long-distance calls from other Philippine provinces: Dial 0-4279-XXX-XXXX (trunk prefix '0' + area code '4279' + subscriber number). For example, to call a number in Lucena from Manila, dial 0-4279-234-5678.
• International calls from outside the Philippines: Dial your country's international access code (usually '00' or '+'), then the Philippines country code +63, followed by the area code without the leading '0', and the subscriber number. For instance, from the United States, dial 011-63-4279-234-5678 or +63-4279-234-5678.

Numbering Plan and Overlay Considerations

As of the latest NTC guidelines, the Philippines has migrated to an 8-digit subscriber numbering scheme for fixed-line services in many areas. However, some provinces, including Quezon, may still use 7-digit numbers. It is essential to verify the current number length with your service provider or the NTC. No overlay codes have been introduced for Quezon, meaning that 4279 remains the sole geographic code for the province's fixed-line services. If you are dialing from a mobile phone within the Philippines, you must still include the trunk prefix '0' and the area code, as mobile-to-landline calls are treated as long-distance.

Practical Examples for Callers

Suppose you are a business traveler in Quezon and need to call a local office: simply dial the 7-digit number. If you are a relative abroad trying to reach a family member in Lucena, you would dial +63 4279 234 5678. Always confirm the exact subscriber number, as omitting the area code when calling from outside the province will result in a failed call.
