Calling Instructions
Callers within Pakistan: Dial the full national number including the trunk prefix. For instance, to reach a Dadu landline from Lahore, you would dial 0 255 7123456.
International callers: Dial your country's international access code (e.g., 011 from the US/Canada, 00 from most European countries), followed by Pakistan's country code 92, then the area code 255 without the leading zero, and the subscriber number. Example from the UK: 00 92 255 7123456.
Important Considerations
Dadu's geographic code is tied to the physical PSTN infrastructure of the region. As with many areas in Pakistan, fixed-line services are provided primarily by the state-owned Pakistan Telecommunication Company Limited (PTCL) and a few licensed operators. The 255 code is not portable to mobile networks; mobile numbers in Pakistan use separate non-geographic prefixes (e.g., 3XX). If you receive a call from +92 255, it originates from a fixed line in the Dadu district. Be mindful of time differences when scheduling calls, as Pakistan Standard Time (PKT) is UTC+5.
