Area Code 8913 – Visakhapatnam, Andhra Pradesh

Overview of Area Code 8913

Area code 8913 is a geographic National Destination Code (NDC) within the Indian numbering plan, allocated to the city of Visakhapatnam in the state of Andhra Pradesh. As part of the +91 country code, this prefix is used for fixed-line (PSTN) services, including traditional copper lines and, increasingly, fixed wireless and VoIP-based landlines. The code is administered under the Telecom Regulatory Authority of India (TRAI) guidelines and is assigned to Bharat Sanchar Nigam Limited (BSNL) and various private operators providing local loop services.

Geographic Coverage and Administration

The 8913 code serves the Visakhapatnam urban agglomeration, including the Greater Visakhapatnam Municipal Corporation (GVMC) area and its surrounding suburbs. It covers key localities such as Dwaraka Nagar, MVP Colony, Gajuwaka, and the industrial zones near the Visakhapatnam Port. As a geographic code, it is tied to the physical location of the subscriber's line, and the number is used for both local and national calls. The code is part of the larger 891 series, which is shared with other districts in the Andhra Pradesh and Telangana border regions, but 8913 specifically routes to Visakhapatnam's wireline exchanges.

Dialing Formats and Instructions

For callers within India, dialing a Visakhapatnam landline requires the full 10-digit number, which includes the area code followed by the subscriber number. For example, to call a number with the prefix 8913, you would dial 08913 XXXXXX (where XXXXXX is the 6-digit local subscriber number). Note that the leading '0' is used for domestic trunk calls. For international callers, the format is +91 8913 XXXXXX (or 011 91 8913 XXXXXX from North America). It is crucial to omit the leading '0' when dialing from abroad.

Local calls within the same NDC (i.e., between two Visakhapatnam landlines) can often be made using only the 6-digit subscriber number, depending on the operator's network configuration. However, with the implementation of the '0' dialing prefix for all NDCs in India (as per TRAI's new dialing rules effective January 2021), callers are advised to always include the full 10-digit number for inter-circle calls. For calls from mobile phones to landlines, the full 10-digit number is always required.

Overlay and Numbering Considerations

Visakhapatnam does not currently have an overlay code; the 8913 code is exclusive to the city's landline network. However, due to the growing demand for fixed-line services, the telecom department may introduce additional codes in the future. Subscribers in Visakhapatnam can retain their numbers when switching operators within the same exchange area, thanks to number portability. For callers, it is important to verify the correct area code, as misdialing may route to a different city in the 891 series, such as Rajahmundry (which uses 883) or Vijayawada (which uses 866).

In summary, 8913 is a vital part of Visakhapatnam's telecommunications infrastructure, enabling reliable voice services for residential and business users. Whether you are a local resident or an international caller, understanding the correct dialing format ensures seamless connectivity to this major port city.
