Area Code 2436 – Khairpur

Overview of Area Code 2436 (Khairpur, Pakistan)

Area code 2436 is a geographic National Destination Code (NDC) assigned to the Khairpur region 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 covers the city of Khairpur and its surrounding administrative areas, including talukas such as Khairpur, Kingri, and Sobho Dero. This code is used for fixed-line (PSTN) services, and in some cases, it may also serve wireless local loop (WLL) connections that are geographically tied to the region.

Dialing Formats

To call a landline in Khairpur from within Pakistan, subscribers must dial the national trunk prefix 0, followed by the area code 2436, and then the subscriber's 7-digit local number. The complete national format is: 0 2436 XXX XXXX. For example, a local number might be dialed as 02436 1234567.

For international callers, the country code for Pakistan is +92. The trunk prefix '0' is omitted, and the number is dialed as: +92 2436 XXX XXXX. For instance, an international caller would dial +92 2436 1234567 to reach the same subscriber.

Geographic Coverage and Administration

Khairpur is the 12th largest city of Pakistan and serves as the headquarters of the Khairpur District. The area code 2436 is allocated to the district's telephone exchange network, which is operated by the state-owned Pakistan Telecommunication Company Limited (PTCL) and other licensed operators. The region is known for its agricultural significance and historical sites, including the Kot Diji Fort and the Sukkur Barrage, which are located nearby. The code is essential for businesses, government offices, and residential users in the district.

Caller Instructions

Local callers within Khairpur can often dial the 7-digit subscriber number directly without the area code, depending on the local exchange configuration. However, for calls from other cities in Pakistan, the full national format with the trunk prefix is required. International callers must always include the country code and area code, omitting the leading '0'. It is important to note that while mobile numbers in Pakistan are non-geographic and begin with 03X, landline numbers under 2436 are fixed and do not support number portability to mobile networks. When dialing from a mobile phone, the same national format applies.

Overlays and Numbering Changes

As of the latest PTA updates, there are no overlay codes for the 2436 area. The numbering capacity is sufficient for the region's demand, and no major changes have been announced. Subscribers should always verify the correct dialing sequence with their service provider, especially when using VoIP services, as some may require an alternative access number.
