Area Code 55 – Western Samar

Overview of Area Code +63 55

Area code 55 is a geographic National Destination Code (NDC) assigned to the Western Samar region of the Philippines. It covers the province of Samar (formerly Western Samar) and its capital, Catbalogan City, along with the municipalities of Calbayog, Basey, Marabut, and other surrounding areas. This code is part of the Philippine numbering plan, which adheres to the ITU-T E.164 standard, and is used for fixed-line (PSTN) services within the region.

Geographic Coverage and Jurisdiction

The +63 55 area code serves the entire province of Samar, which is located in the Eastern Visayas region (Region VIII). The province is divided into two congressional districts, and the area code covers both. Key cities and municipalities under this code include Catbalogan (the provincial capital), Calbayog City, and the towns of Gandara, Tarangnan, and Jiabong. The region is primarily agricultural and coastal, with Catbalogan serving as a major commercial and administrative hub.

Dialing Formats

For local calls within the same area code, callers can dial the 7-digit subscriber number directly. For calls from other parts of the Philippines, the format is 0 55 XXX XXXX (trunk prefix 0, area code 55, and the 7-digit local number). International callers should dial +63 55 XXX XXXX (country code 63, area code 55 without the leading 0, and the local number). For example, a local number in Catbalogan might be formatted as +63 55 123 4567.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for the 55 area code; it remains a standalone geographic code. The National Telecommunications Commission (NTC) of the Philippines oversees the allocation and management of numbering resources. Subscriber numbers within this area code are typically 7 digits long, and the total length of a national significant number (NSN) is 10 digits (including the area code).

Caller Instructions

For callers within Samar: simply dial the 7-digit number. For callers from other parts of the Philippines: dial 0 55 followed by the 7-digit number. For international callers: dial your country's exit code (e.g., 00 or 011), then 63, then 55, and the 7-digit number. It is important to omit the leading '0' when dialing from abroad.

Services and Usage

The area code supports both residential and business fixed-line services, including internet (DSL/fiber) and traditional telephony. Major telecommunications providers in the Philippines, such as PLDT and Globe Telecom, operate in this region. The code is also used for fax and alarm systems. As with all geographic codes, number portability may allow users to retain their number when switching providers, but the geographic association remains tied to the physical location of the line.
