Area Code 216 – Karachi

Geographic Overview

The +92 216 area code is a geographic National Destination Code (NDC) assigned to the city of Karachi, the largest metropolis and economic hub of Pakistan. Karachi is the capital of the Sindh province and serves as the country's primary financial, industrial, and commercial center. The area code 216 specifically covers the central and eastern districts of Karachi, including major business districts such as Saddar, Clifton, and Gulshan-e-Iqbal. This code is part of the broader Karachi numbering plan, which historically used 21 as the city's area code; the addition of the third digit (6) allows for a larger subscriber numbering capacity.

Dialing Formats

For callers within Pakistan, the local dialing format is 0216-XXXXXXX (where X represents the subscriber number, typically 7 digits). When dialing from outside Pakistan, the international format is +92 216 XXXXXXX or +92216XXXXXXX. It is essential to drop the leading '0' of the area code when dialing internationally. For example, a local number 1234567 would be dialed as 0216-1234567 within Pakistan and as +92 216 1234567 from abroad.

Caller Instructions

• Local callers (within Pakistan): Dial the full NDC including the trunk prefix '0' followed by the subscriber number. For instance, to call a landline in Karachi's 216 area, dial 0216-XXXXXXX.
• International callers: Dial your country's exit code (e.g., 00 or +), then Pakistan's country code 92, followed by the area code without the leading '0' (216), and then the subscriber number. Example: +92 216 1234567.

Overlay and Numbering Considerations

Karachi has multiple geographic area codes (21, 22, 23, 24, 25, 26, 27, 28, 29) to accommodate its vast subscriber base. The 216 code is one of these overlays, and it does not require any special dialing changes for local calls; all calls within Pakistan use the full NDC. As of the latest Pakistan Telecommunication Authority (PTA) guidelines, no new overlays have been announced, but the numbering plan remains flexible to support future growth.

Technical Notes

All geographic numbers in Pakistan are fixed-line services, primarily provided by the state-owned Pakistan Telecommunication Company Limited (PTCL) and private operators such as StormFiber and Nayatel. These numbers are assigned to physical locations and are used for PSTN and VoIP services. When porting a number, the geographic location is retained, but the service provider may change. For international call routing, the +92 216 code is recognized by global carriers as a geographic number, and calls are routed via the public switched telephone network (PSTN) to the appropriate local exchange.
