Area Code 8613 – Nellore, Andhra Pradesh

Geographic Coverage and Administrative Jurisdiction

The +91 8613 area code is a geographic National Destination Code (NDC) assigned to the Nellore district in the state of Andhra Pradesh, India. This code covers the city of Nellore and its surrounding administrative subdivisions, including rural mandals that rely on the same Public Switched Telephone Network (PSTN) infrastructure. As a fixed-line code, it is tied to the telecom circle of Andhra Pradesh, historically operated by state-owned BSNL and now also served by private operators such as Airtel and Jio for landline services.

Primary Cities and Local Dialing

The primary urban center served by this code is Nellore city, located on the banks of the Penna River. Other towns and villages within the district, such as Kavali, Gudur, and Sullurpeta, may use different STD codes (e.g., 08626 for Kavali) depending on their specific exchange areas. For local calls within the 8613 area, subscribers can dial the 7-digit subscriber number directly without the area code. For example, a local call to a number like 2345678 would be dialed as just 2345678.

International and National Dialing Formats

To call a landline in Nellore from another country, the international format is: +91 8613 XXXXXXX (where XXXXXXX is the 7-digit subscriber number). From a mobile phone within India, you must dial the full number including the area code: 08613 XXXXXXX. From a fixed line in a different STD code area, the same format applies: 0 8613 XXXXXXX. The leading '0' is the trunk prefix used for domestic long-distance calls, while '+91' is the country code for India.

Overlay and Numbering Plan Considerations

As of the latest telecom regulatory updates, there is no overlay code for the 8613 area. The district follows the standard 10-digit numbering scheme for landlines (excluding the trunk prefix). However, with the increasing adoption of VoIP and fixed wireless access, some numbers may be routed over IP networks, but the dialing format remains unchanged. Callers should note that while mobile numbers in India are 10 digits long and start with 9, 8, 7, or 6, landline numbers under 8613 have a distinct format: the area code followed by a 7-digit subscriber number.

Caller Instructions

For local callers within Nellore: simply dial the 7-digit number. For domestic callers outside the area: dial 0 then 8613 then the 7-digit number. For international callers: dial your country's exit code (e.g., 011 from the US, 00 from most European countries), then 91, then 8613, then the 7-digit number. Always omit the leading '0' when dialing from abroad. This code is exclusively for fixed-line services; mobile numbers in the region are allocated under non-geographic mobile prefixes like 91 9XXXX XXXXX.
