Area Code 43 – Viqueque

Overview of Timor-Leste Country Code +670 and Area Code 43

Timor-Leste, officially the Democratic Republic of Timor-Leste, is assigned the international country calling code +670 by the International Telecommunication Union (ITU) under the E.164 standard. Unlike many countries that use a trunk prefix (e.g., 0) and separate area codes, Timor-Leste employs a closed numbering plan where the full national significant number (NSN) is dialed directly after the country code. Geographic area codes are an integral part of the NSN, and the prefix 43 designates the municipality of Viqueque, located in the southeastern part of the country.

Geographic Coverage and Administrative Jurisdiction

The area code 43 serves the entire municipality of Viqueque, one of Timor-Leste's 13 administrative municipalities. Viqueque is bordered by the municipalities of Baucau to the north, Lautém to the east, Manatuto to the west, and the Timor Sea to the south. The municipality is subdivided into five administrative posts: Viqueque (the capital), Lacluta, Ossu, Uato-Lari, and Uato-Carbau. The code covers both the urban center of Viqueque city and the surrounding rural areas, including villages such as Ossu and Uato-Lari. Fixed-line telephone services in this region are provided by the national telecommunications operator, Timor Telecom, and more recently by other licensed operators such as Telemor and Telkomcel, though fixed-line infrastructure is primarily concentrated in the municipal capital and administrative centers.

Dialing Formats and Caller Instructions

To call a fixed-line number in Viqueque from abroad, subscribers must dial the international access prefix (e.g., 00 or +) followed by the country code 670, then the area code 43, and finally the local subscriber number. The national significant number for Viqueque fixed lines is 8 digits long, beginning with 43. For example, a local number might be formatted as 43X XXXX (where X represents digits). From outside Timor-Leste, the complete international format would be +670 43X XXXX. For instance, if the local number is 431 2345, the international dialing format is +670 431 2345.

Callers within Timor-Leste do not need to dial a trunk prefix; they simply dial the 8-digit national number directly, e.g., 431 2345. This applies to both local and long-distance calls within the country. It is important to note that Timor-Leste does not use a trunk prefix like '0' or '1'; the country code +670 is used only for international calls.

Overlay Considerations and Numbering Plan

Currently, there are no overlay codes for Viqueque; the area code 43 is exclusive to this municipality. However, as the demand for fixed-line services grows, the regulatory authority, Autoridade Nacional das Comunicações (ANC), may introduce additional geographic codes or overlay plans. Subscribers should always verify the correct number with the recipient, especially when calling mobile numbers, which are non-geographic and have distinct prefixes (e.g., 74, 75, 76, 77, 78, 79 for Timor Telecom, Telemor, and Telkomcel).

For foreign callers, it is essential to replace the '+' with the appropriate international access code from their country (e.g., 011 from the US, 00 from most European countries). For example, from the US, a call to Viqueque would be dialed as 011 670 431 2345. From the UK, it would be 00 670 431 2345.

In summary, the area code 43 is a geographic identifier for Viqueque, Timor-Leste. Understanding the correct dialing format ensures successful connectivity to this region.
