Area Code 25 – Sonsorol State and Hatohobei State

Overview of Palau Area Code 25

Area code 25 is a geographic National Destination Code (NDC) assigned to the remote southwestern islands of Palau, specifically covering Sonsorol State and Hatohobei State (also known as Tobi Island). These states are part of the Palauan archipelago in the western Pacific Ocean and are among the most isolated communities in the country. The code is used for fixed-line (PSTN) services within these states, connecting residents and the few government or administrative outposts to the national and international telephone network.

Geographic Coverage and Administration

Sonsorol State encompasses the islands of Sonsorol, Fanna, and Pulo Anna, while Hatohobei State includes Tobi Island and the nearby Helen Reef. Both states are governed under Palau's administrative divisions, with limited infrastructure and small populations. The area code 25 is allocated exclusively to these states, ensuring that calls are routed correctly to the appropriate island's local exchange. Due to the remote nature of these islands, telecommunication services are often provided via satellite or high-frequency radio links, but the numbering plan remains consistent with Palau's national framework.

Dialing Formats and Caller Instructions

To call a fixed-line number in Sonsorol or Hatohobei from abroad, you must dial the international prefix (e.g., 011 from the US, 00 from most countries), followed by Palau's country code +680, then the area code 25, and the local subscriber number. For example, if the local number is 1234, the international format would be +680 25 1234. Within Palau, callers can dial the area code and subscriber number directly without the country code, but the national dialing plan may require the leading '1' or '0' depending on the operator; always consult local guidelines. For callers outside Palau, it is crucial to omit any leading trunk prefix and use the full international sequence.

Numbering and Overlay Considerations

Palau's numbering plan follows ITU-T E.164, with a total number length of 7 digits for geographic numbers, including the NDC. The area code 25 is not overlaid with other codes; it is a dedicated geographic code. As of now, there are no known overlay plans for this region. The subscriber numbers within area code 25 are typically 4 digits, but this may vary; always verify the exact number length with the local provider. For international callers, the complete number after the country code should be 7 digits (e.g., 25 1234).

Practical Tips for Callers

• International callers: Use the format +680 25 XXXX. Ensure you have international dialing capability on your phone plan.
• Local callers within Palau: Dial 25 XXXX (or as per local instructions).
• Emergency and assistance: For local emergency services, use the national emergency numbers, not this area code.
• Time zone: Palau is in UTC+9, with no daylight saving time, so plan your calls accordingly.
