Area Code 322 – Lamongan

Overview of Area Code 322

Area code 322 is a geographic National Destination Code (NDC) within the Indonesian numbering plan, assigned to the Lamongan Regency in the province of East Java (Jawa Timur). This code is part of the +62 country calling code and is used for fixed-line (PSTN) services within the Lamongan area. The region is located on the northern coast of East Java, approximately 50 kilometers west of Surabaya, the provincial capital. Lamongan is known for its coastal economy, agriculture, and small-to-medium enterprises, which rely on local telephony for business and administrative communications.

Geographic Coverage and Administrative Jurisdiction

The 322 area code covers the entire administrative regency of Lamongan, including its capital, also named Lamongan, and surrounding districts such as Babat, Paciran, and Brondong. The code is allocated to the local fixed-line network, which is operated by PT Telkom Indonesia and other licensed PSTN providers. As a geographic code, it is tied to the physical location of the subscriber's line, meaning that calls to 322 numbers are routed to the Lamongan exchange.

Dialing Formats and Caller Instructions

Understanding the correct dialing format is essential for both domestic and international callers.

• Domestic calls within Indonesia (from outside Lamongan): Dial 0-322-XXXXXXX. The leading '0' is the trunk prefix used for domestic long-distance calls. The subscriber number typically consists of 7 to 8 digits, depending on the exchange capacity.
• Local calls within Lamongan (same area code): In many Indonesian fixed-line networks, local calls can be made using only the subscriber number without the area code. However, this practice is becoming less common due to number portability and overlay plans. It is recommended to always include the area code for reliability.
• International calls to Lamongan: Dial +62-322-XXXXXXX from any country. The '+' sign represents the international access prefix (e.g., 011 from the US, 00 from many European countries), followed by the country code 62, the area code 322 (without the leading '0'), and the subscriber number.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, there are no overlay codes for Lamongan; 322 remains the sole geographic code for the regency. However, with the ongoing migration to VoIP and the introduction of number portability, subscribers may retain their 322 numbers even if they move to a different physical location within Indonesia, as long as the service provider supports it. This is a significant shift from traditional geographic routing.

Practical Examples

To illustrate, a fixed-line number in Lamongan might be 0322-5551234 domestically. From abroad, you would dial +62 322 5551234. If you are in Surabaya (area code 31), you would dial 0322-5551234 to reach Lamongan. These examples ensure clear communication for both business and personal calls.
