Area Code 4029 – Terokhada

Overview of Terokhada (Area Code 4029)

The telephone area code 4029 is a geographic National Destination Code (NDC) assigned to the Terokhada sub-district (upazila) within the Khulna District of Bangladesh. It is part of the country's public switched telephone network (PSTN) and is used for fixed-line (landline) services. The code is administered under the national numbering plan of Bangladesh, which follows the ITU-T E.164 international standard.

Geographic Coverage and Administration

Terokhada is an upazila located in the southern part of Khulna District, within the Khulna Division. The area code covers the administrative jurisdiction of Terokhada Upazila, including its union councils and surrounding rural areas. The primary town of Terokhada serves as the local administrative and commercial center. This code is exclusively for fixed-line connections and is not assigned to mobile or VoIP services.

Dialing Procedures

To call a landline number in Terokhada from within Bangladesh, subscribers must dial the trunk prefix 0 followed by the area code 4029 and the subscriber's 6-digit local number. For example, if the local number is 123456, the national dialing format is 0 4029 123456. From abroad, callers must dial the international access code (e.g., 00 from most countries) followed by the country code 880, then the area code without the leading zero, and the local number: +880 4029 123456.

Numbering and Overlay Considerations

In Bangladesh, geographic area codes are typically 2 to 4 digits long, and the subscriber number length varies accordingly. For the 4-digit code 4029, the local subscriber number is 6 digits, making the total national significant number (NSN) 10 digits (including the leading 0). As of the latest ITU-T operational bulletin, no overlay code has been assigned for this area. Therefore, local calls within Terokhada may be made using the local number alone if the caller is within the same exchange area, but for calls from other districts, the full national format must be used.

Guidance for Callers

• Local callers (within Terokhada): If your telephone exchange is the same, you may dial only the 6-digit local number. However, if you are unsure, always dial the full national format.
• National callers (outside Terokhada): Dial 0-4029-XXXXXX.
• International callers: Dial your country's exit code, then 880-4029-XXXXXX.

Ensure you replace XXXXXX with the actual 6-digit subscriber number. This area code is used for both residential and business fixed-line services, including government offices and local enterprises.
