📍 Geographic Location of Nellore, Andhra Pradesh
Geographic Coverage and Administrative Jurisdiction
The +91 8616 country calling code and STD prefix corresponds to a geographic numbering plan area (NPA) in the state of Andhra Pradesh, India. Specifically, it serves the Nellore district, with the city of Nellore as the primary urban center. The jurisdiction encompasses the Nellore Municipal Corporation and its surrounding suburban and rural areas, including localities such as Sullurpeta, Gudur, and Venkatagiri, which are within the district's telecom administrative boundaries. This prefix is allocated under the National Numbering Plan of India, administered by the Department of Telecommunications (DoT), and follows the ITU-T E.164 international standard.
Dialing Formats and Number Structure
When dialing a landline number in Nellore from within India, subscribers must use the full STD code 0 followed by the subscriber number. For example, a local number might be formatted as 0-8616-XXXXXX (where X represents the six-digit subscriber line number). Internationally, callers from outside India should dial +91 8616 XXXXXX, omitting the leading zero of the STD code. The total length of a complete international number, including the country code, is 12 digits (e.g., +91 8616 123456). It is important to note that the 8616 prefix is a geographic code, meaning that the tariff and routing are based on the physical location of the line, not on the service provider.
Overlay and Local Calling Considerations
As of the latest DoT numbering plan, there is no overlay code for the Nellore area; 8616 remains the sole geographic code for this region. Local calls within the same STD area do not require the STD code; subscribers can dial the six-digit number directly. However, calls from other parts of India must include the full STD code. For callers within India, the call charges are determined by the distance and the operator's tariff policy, while international callers will incur rates set by their respective telecom providers. For VoIP users, it is essential to use the correct international format to ensure proper routing through the PSTN gateway.
Service Providers and Number Portability
Landline services in the 8616 area are primarily provided by BSNL (Bharat Sanchar Nigam Limited), which historically holds the majority of fixed-line connections in the region. Private operators, such as Airtel and Jio, also offer fixed-line services in Nellore using the same geographic prefix. Thanks to the implementation of full mobile number portability (MNP) and fixed-line number portability in India, subscribers can retain their 8616 numbers even if they switch to a different operator, provided they remain within the same geographic area. This ensures that the prefix remains a reliable identifier for the Nellore region, irrespective of the underlying service provider.
