Area Code 3427 – Ukhiya

Overview of Area Code 3427 (Ukhiya, Bangladesh)

Area code 3427 is a geographic National Destination Code (NDC) assigned to the Ukhiya sub-district (upazila) in the Cox's Bazar District of Chittagong Division, Bangladesh. This code is part of the national numbering plan administered by the Bangladesh Telecommunication Regulatory Commission (BTRC) under the ITU-T E.164 standard. Ukhiya is located in the southeastern part of the country, near the Myanmar border, and is known for hosting the world's largest refugee settlement, the Kutupalong camp. The area code serves both fixed-line (PSTN) and fixed wireless (WLL) services within the Ukhiya administrative boundary, including its union councils and adjacent localities.

Geographic Coverage and Administrative Jurisdiction

The 3427 code covers the entire Ukhiya upazila, which is subdivided into several unions, including Ukhiya Sadar, Palongkhali, Jaliapara, Raja Palong, and Ratna Palong. These areas are primarily rural, with a mix of agricultural and small commercial activities. The code is also used in nearby market towns and bazaars that fall under the upazila's jurisdiction. For administrative purposes, Ukhiya is under the Cox's Bazar District, and calls to other parts of Cox's Bazar (e.g., the district headquarters) may require different area codes, such as 341 for Cox's Bazar town.

Dialing Formats and Caller Instructions

To call a landline number in Ukhiya from within Bangladesh, subscribers must dial the trunk prefix '0' followed by the area code 3427 and the subscriber's 6-digit local number. For example, if the local number is 123456, the complete national dialing format is 0-3427-123456. From abroad, callers must use the international access prefix (e.g., 00 from most countries) followed by Bangladesh's country code +880, then the area code 3427 (without the leading '0') and the local number: +880-3427-123456.

Local calls within the same area code may be dialed using only the 6-digit subscriber number, depending on the operator's network configuration. However, for clarity and to avoid misdialing, it is recommended to use the full national format. Mobile phone users in Bangladesh can dial the national format directly. International callers should note that the plus sign (+) represents the international exit code, which varies by country (e.g., 011 from the US, 00 from most European countries).

Overlay and Numbering Considerations

As of the latest BTRC updates, there is no overlay code for Ukhiya; the 3427 code is exclusively used for the upazila. However, due to the growing demand for telecommunication services in the area, especially with the presence of humanitarian organizations and NGOs, the BTRC may introduce additional numbering capacity in the future. Subscribers should always verify the correct area code when placing calls, as dialing the wrong code may result in misrouted calls or additional charges. For international callers, it is essential to omit the leading '0' of the area code when dialing from abroad.
