Area Code 334 – Lumajang

Geographic Overview

The +62 334 country and area code combination is assigned to the Lumajang geographic region in East Java, Indonesia. This code is part of the national numbering plan administered by the Indonesian Telecommunication Regulatory Authority (BRTI) under ITU-T E.164 recommendations. Lumajang is a regency located approximately 120 kilometers southeast of Surabaya, the provincial capital. The area code covers the administrative jurisdiction of Lumajang Regency, including the capital city of Lumajang and surrounding districts such as Yosowilangun, Kunir, and Pasirian.

Dialing Formats

For callers within Indonesia, the domestic trunk prefix '0' is used before the area code. Therefore, local calls within the Lumajang region require dialing 0334 followed by the subscriber number. For example, a typical local number might be 0334-XXXXXXX (7-digit subscriber number). When calling from outside Indonesia, the international access code (usually '00' or '+') is used, followed by the country code 62, then the area code without the leading '0'. Thus, an international caller would dial +62 334-XXXXXXX. It is essential to omit the leading '0' when dialing from abroad.

Geographic and Administrative Coverage

The 334 area code is strictly geographic, meaning it is tied to the physical location of the fixed-line telephone exchange. It serves both residential and business customers within the Lumajang Regency. The region is known for its agricultural economy, including coffee, rice, and horticulture, as well as tourism attractions such as the Ranu Kumbolo Lake and Mount Semeru, Java's highest peak. Consequently, the area code is used by local government offices, businesses, and residents in these areas.

Overlay and Numbering Considerations

As of the latest updates, there is no overlay code for Lumajang, meaning the 334 area code is the sole geographic code for this region. However, with the growth of telecommunications services, the number of digits in subscriber numbers may vary. It is important to note that while mobile numbers in Indonesia are non-geographic and begin with 08, fixed-line numbers under 0334 are tied to the Lumajang exchange. Callers should always verify the complete number, including the area code, to ensure proper routing.

Instructions for Callers

• Local callers (within Lumajang): Dial the 7-digit subscriber number directly, or include the area code if calling from outside the local calling area.
• National callers (outside Lumajang): Dial 0334-XXXXXXX.
• International callers: Dial +62 334-XXXXXXX.

Understanding the correct dialing format is crucial for seamless connectivity. Whether you are a business establishing a presence in Lumajang or an individual contacting local services, using the proper country and area codes ensures your call reaches the intended destination without interruption.
