Area Code 27 – Angaur State

Geographic Overview

Area code 27 is a geographic National Destination Code (NDC) assigned to Angaur State, one of the sixteen states of the Republic of Palau. Angaur is a small raised coral island located approximately 10 kilometers southwest of Peleliu and about 40 kilometers from the main island of Babeldaob, where the national capital, Ngerulmud, is situated. The island has a population of around 120 residents, primarily concentrated in the village of Ngeremasch. Due to its small size and limited subscriber base, the 27 prefix is used for all fixed-line services within the state, including residential, governmental, and commercial lines.

Dialing Formats

When calling an Angaur number from within Palau, subscribers must dial the full national number, which includes the area code and the subscriber number. The local format is 27X XXXX, where the first digit after the area code is part of the subscriber number. For example, a typical fixed-line number might appear as 275 1234.

For international callers, the Palau country code +680 must be used, followed by the area code and subscriber number without any leading trunk prefix. The international format is +680 27X XXXX. For instance, to call a number in Angaur, you would dial +680 275 1234 from abroad.

Calling Instructions

• Local callers (within Palau): Dial the 7-digit national number directly, e.g., 275 1234. No trunk prefix (such as '0') is used in Palau.
• International callers: Dial your country's exit code (e.g., 011 from the US, 00 from many European countries), then Palau's country code 680, followed by the area code and subscriber number: +680 275 1234.

Technical Considerations

Angaur's fixed-line network is part of the Palau National Communications Corporation (PNCC) infrastructure, which operates a digital PSTN. The island is connected to the main Palau network via microwave and submarine fiber links, ensuring reliable voice and data services. As of recent years, there have been no overlay codes or number portability issues affecting the 27 area code. However, with the increasing adoption of VoIP and mobile services, some residents may use alternative numbering, but the 27 prefix remains the sole geographic identifier for Angaur.

For businesses or government agencies operating in Angaur, it is essential to ensure that their contact numbers are correctly formatted on international directories and websites, as improper formatting can lead to call failures. Always verify the number length and include the country code when publishing contact details for global audiences.
