Area Code 406 – Sahiwal

Overview of Pakistan Area Code 406

Area code 406 is a geographic National Destination Code (NDC) assigned to the Sahiwal region in the Punjab province of Pakistan. It is used for fixed-line (PSTN) services within the Sahiwal District, which includes the city of Sahiwal and its surrounding administrative subdivisions. The code is part of Pakistan's national numbering plan, which adheres to ITU-T E.164 recommendations, and is administered by the Pakistan Telecommunication Authority (PTA).

Geographic Coverage and Administrative Jurisdiction

Sahiwal is a major city in south-central Punjab, situated between Lahore and Multan. The 406 area code covers the entire Sahiwal District, including the tehsils of Sahiwal, Chichawatni, and Noor Shah. It also serves adjacent rural areas and smaller towns that rely on the Sahiwal telephone exchange. The region is an important agricultural and industrial hub, with a growing population and expanding telecommunications infrastructure.

Dialing Formats and Caller Instructions

Understanding the correct dialing sequence is essential for both domestic and international callers.

• Domestic Calls (within Pakistan): To call a Sahiwal landline from another city in Pakistan, dial the trunk prefix 0, followed by the area code 406, and then the subscriber's 7-digit local number. For example, to reach a number in Sahiwal, you would dial: 0 406 XXX XXXX.
• International Calls (from outside Pakistan): Callers from abroad must dial the international access prefix of their country (e.g., 00 in most of Europe, 011 in the US/Canada), followed by Pakistan's country code +92, then the area code 406 (without the leading zero), and the 7-digit local number. The international format is: +92 406 XXX XXXX.
• Local Calls (within Sahiwal): For calls made within the same exchange area, it may be possible to dial only the 7-digit local number, depending on the operator's dialing plan. However, for clarity and consistency, it is recommended to use the full national format.

Overlay and Numbering Considerations

Currently, there is no overlay code for the Sahiwal area; the 406 code remains the sole geographic code for the district. However, as demand for fixed-line services grows, the PTA may introduce additional numbering resources. Subscribers in Sahiwal can also be reached via mobile networks, but mobile numbers use separate non-geographic prefixes (e.g., 0300, 0311, etc.) and are not tied to the 406 area code.

Important Notes for Callers

• When dialing internationally, always omit the leading '0' of the area code.
• Check with your service provider for any special rates or restrictions on international calls to Pakistan.
• For emergency services within Sahiwal, use the national emergency numbers (e.g., 15 for police, 115 for rescue) rather than the area code.
