Area Code 2644 – Jambusar, Gujarat

Overview of Area Code 2644

Area code +91 2644 is a geographic National Destination Code (NDC) assigned to the town of Jambusar and its surrounding areas in the Bharuch district of the western Indian state of Gujarat. This code is part of the Indian telecom numbering plan, which follows the ITU-T E.164 international standard. The region is known for its industrial significance, particularly the Gujarat Industrial Development Corporation (GIDC) estate, and its proximity to the Gulf of Khambhat.

Geographic Coverage and Administrative Jurisdiction

The 2644 area code serves the administrative jurisdiction of Jambusar Taluka, which includes the town itself and numerous villages. Key localities covered under this code include Jambusar, Amod, and Vagra (partially), as well as industrial zones and agricultural belts. The region is strategically located near the National Highway 48 (old NH-8) and is well-connected to major cities like Vadodara (approximately 70 km) and Ahmedabad (approximately 120 km).

Dialing Formats and Caller Instructions

For callers within India, dialing a local number in Jambusar requires the full 10-digit format: 0 2644 XXXXXX (where XXXXXX is the six-digit subscriber number). For example, to call a landline in Jambusar from another Indian city, you would dial 02644 123456. International callers must use the country code for India, followed by the area code without the leading trunk prefix '0': +91 2644 XXXXXX. For instance, from the United States, you would dial 011 91 2644 123456 (or use the '+' sign on mobile phones).

Numbering Plan and Overlay Considerations

As of the current numbering plan, the 2644 area code does not have an overlay. Subscriber numbers are six digits long, making the total length of a national significant number (NSN) 10 digits (including the leading '0' for domestic calls). The fixed-line services in this region are primarily provided by state-owned BSNL and private operators like Reliance Jio and Bharti Airtel, which offer landline services over fiber or copper networks. No major overlay is planned, but telecom regulators may introduce changes in the future to accommodate growing demand.

Additional Information for Callers

When calling from a mobile phone within India, it is essential to include the area code even if you are in the same city, as mobile numbers are not geographically tied. For international callers, always replace the trunk prefix '0' with the country code '+91'. The time zone for Jambusar is India Standard Time (IST, UTC+5:30). For emergency services, dial 112 (national emergency number) or 100 (police), which are accessible from any phone. For business or personal calls, ensure you have the correct six-digit subscriber number, as numbers may have been ported under Mobile Number Portability (MNP) only for mobile numbers, not fixed lines.
