Area Code 381 – Laximpur/Ramganj

Overview of Area Code +880 381

The country calling code +880 is assigned to Bangladesh under the ITU-T E.164 international numbering plan. The national destination code (NDC) 381 is a geographic area code that routes calls to the Laximpur/Ramganj region, located in the Chittagong Division of southeastern Bangladesh. This code is administered by the Bangladesh Telecommunication Regulatory Commission (BTRC) and is used for fixed-line (PSTN) services within the designated local service area.

Geographic Coverage and Administrative Jurisdiction

The +880 381 code covers the administrative district of Laximpur (also spelled Lakshmipur) and its sub-district (upazila) of Ramganj. The region is part of the greater Noakhali area and is bordered by the Meghna River to the west. Key towns served by this code include Laximpur Sadar, Ramganj, and nearby rural communities. The area is primarily agricultural, with growing small and medium enterprises, which rely on reliable fixed-line connectivity for business operations.

Dialing Formats and Caller Instructions

For international callers, the complete number format is +880 381 XXX XXX, where the subscriber number is typically 7 digits long. When dialing from abroad, replace the leading zero of the national trunk prefix with the international access code (e.g., 00 from most countries) followed by 880 and then the area code without the leading zero. For example, to call a number in Ramganj, you would dial +880 381 123 4567.

For domestic callers within Bangladesh, the national dialing format requires the trunk prefix 0 before the area code: 0 381 XXX XXX. Local calls within the same area code may be dialed using only the 7-digit subscriber number, depending on the operator's local dialing rules. However, due to the implementation of the national numbering plan, it is recommended to always use the full national format to avoid misdialing.

Overlay and Numbering Considerations

As of the latest BTRC updates, there is no overlay code for the Laximpur/Ramganj area; the 381 code remains the sole geographic code for this region. Subscriber numbers are fixed at 7 digits, making the total national significant number (NSN) 10 digits (including the leading 0). This structure aligns with the ITU-T E.164 recommendation for Bangladesh, which mandates a maximum of 15 digits for international numbers.

Callers should be aware that while mobile numbers in Bangladesh are non-geographic and begin with 1 (e.g., 013, 017), fixed-line numbers like those under 381 are tied to physical locations. This distinction is important for routing and for understanding potential differences in call charges, as fixed-line calls are typically tariffed based on distance and duration.
