Area Code 8782 – Karimnagar, Andhra Pradesh

Geographic Overview

The +91 8782 area code is a geographic National Destination Code (NDC) assigned to the city of Karimnagar, located in the state of Telangana, India (historically part of Andhra Pradesh before the state bifurcation in 2014). This code covers the Karimnagar urban agglomeration and its surrounding administrative district, including towns such as Huzurabad, Jagtial, and Metpally. The service area is part of the Hyderabad telecom district's secondary switching area, and it is administered under the jurisdiction of the Department of Telecommunications (DoT) for the Telangana circle.

Dialing Formats

For local callers within India, the dialing format is 0-8782-XXXXXX, where the leading '0' is the trunk prefix used to access the national long-distance network. For international callers, the format is +91-8782-XXXXXX (or 011-91-8782-XXXXXX when dialing from the US/Canada). Subscribers within the same NDC area can often dial the six-digit local number directly without the area code, depending on the specific local exchange configuration. The subscriber number length is six digits, making the total national significant number (NSN) ten digits (including the leading '0' for domestic calls).

Network and Overlays

Karimnagar's PSTN infrastructure is primarily served by fixed-line operators such as BSNL, which historically held the monopoly. In recent years, private operators like Airtel and Reliance Jio have also deployed fixed-line and VoIP services in the region, but the 8782 code remains associated with the geographic area. There are no overlay codes currently planned for Karimnagar; the 8782 code is exclusive to this region. However, as part of India's National Numbering Plan, the DoT periodically reviews numbering resources, and future overlays may be introduced if the existing code exhausts.

Caller Instructions

For local callers within Karimnagar: if you are dialing from a fixed-line phone within the same short-distance charging area (SDCA), you may omit the area code and dial just the six-digit subscriber number. For callers from other parts of India, always dial 0-8782-XXXXXX. For international callers, replace the trunk prefix with your country's international access code (e.g., 00 from most European countries) followed by 91-8782-XXXXXX. Note that mobile numbers in India are not prefixed with 8782; they use separate mobile NDCs such as 98, 99, etc. When calling a Karimnagar fixed-line number from a mobile phone, the '0' is often optional, but it is recommended to include it for clarity.

Regulatory and Technical Notes

As per ITU-T E.164, the country code for India is +91, and the NDC length is two to four digits. The 8782 code is a four-digit NDC, which is typical for smaller cities. The numbering plan is closed, meaning that the full national number must be dialed for all calls, even local ones, when using mobile phones. The DoT has mandated that all fixed-line numbers be dialed with the area code from mobile networks to avoid ambiguity. This area code is also used for non-geographic services like fax and data lines, but the primary use remains PSTN voice.
