Overview of Area Code 259 (Dadu, Pakistan)
Area code 259 is a geographic National Destination Code (NDC) assigned to the Dadu District in the Sindh province of Pakistan. It is part of the national numbering plan administered by the Pakistan Telecommunication Authority (PTA) under the ITU-T E.164 standard. The code serves the administrative city of Dadu and its surrounding talukas, including Khairpur Nathan Shah, Mehar, and Johi. Calls to this region require the full international format when dialing from abroad: +92 259 [local number].
Local Dialing Format
Within Pakistan, callers must dial the trunk prefix 0 before the area code when making domestic long-distance calls. The complete domestic format is 0 259 [local number]. Local numbers in Dadu typically consist of 6 to 7 digits. For example, a local landline number might be 123456, so a domestic caller from Karachi would dial 0259 123456. From a mobile phone within Pakistan, the same number is dialed as 0259 123456 (the leading 0 is still required).
International Dialing Format
For international callers, the country code for Pakistan is +92. The trunk prefix 0 is omitted. Therefore, to reach a Dadu landline from the United States, United Kingdom, or any other country, dial: +92 259 123456. Ensure you replace the example local number with the actual 6-7 digit subscriber number.

Overlay and Numbering Considerations
As of the latest PTA updates, there is no overlay code for Dadu; 259 remains the sole geographic code for the district. However, due to the increasing adoption of mobile and VoIP services, some businesses may use non-geographic numbers for customer service. When dialing a Dadu number, always verify the subscriber number length, as it may vary. For any technical issues, contact your service provider or the PTA.
