Area Code 713 – Sukkur

Geographic Coverage and Administrative Jurisdiction

The area code 713 is a geographic National Destination Code (NDC) assigned to the city of Sukkur and its surrounding administrative areas in the Sindh province of Pakistan. This code covers the Sukkur District, including the municipal corporation limits of Sukkur city, as well as nearby towns and settlements that fall within the same local calling area. The region is a major commercial and transit hub along the Indus River, and the code serves both residential and business fixed-line subscribers within this defined PSTN exchange area.

Dialing Formats and Number Structure

Within Pakistan, calls to a Sukkur landline must be dialed as 0-713-XXXXXX, where 0 is the trunk prefix, 713 is the area code, and the subscriber number is typically six digits long. For example, a local number might be formatted as 0-713-123456. When dialing from outside Pakistan, the international format is +92-713-XXXXXX, replacing the leading zero with the country code +92. For instance, an international caller would dial +92713123456 to reach the same subscriber.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Sukkur area, meaning that the 713 code is exclusive to this geographic region. However, as with all fixed-line services in Pakistan, the number of digits may vary slightly depending on the specific exchange and the operator. Subscribers should always verify the exact number of digits with their service provider. The Pakistan Telecommunication Authority (PTA) manages the national numbering plan, and any changes to the area code structure would be announced well in advance.

Caller Instructions

• Local callers (within Sukkur): If you are calling from another fixed-line number within the same exchange area, you may be able to dial only the six-digit subscriber number without the area code. However, for clarity and to avoid misdialing, it is recommended to always use the full national format: 0-713-XXXXXX.
• National callers (from other cities in Pakistan): Dial 0-713-XXXXXX. For example, to call a Sukkur number from Karachi, you would dial 0-713-123456.
• International callers: Dial your country's international access code (e.g., 00 from most countries), then Pakistan's country code 92, followed by the area code 713 (without the leading zero) and the subscriber number. Example: +92 713 123456 or 00-92-713-123456.

It is important to note that mobile numbers in Pakistan are non-geographic and begin with 3 (e.g., 0300, 0321), so they are not affected by this area code. When calling a Sukkur landline from a mobile phone, you must still include the 0-713 prefix.
