It is part of the country's E.164 numbering plan, where the full international dialing format is +92 4548 XXXXXX. The code serves the administrative city of Khushab and its surrounding rural areas, including towns such as Jauharabad, Hadali, and Noorpur Thal. As a fixed-line prefix, 4548 is primarily used by Pakistan Telecommunication Company Limited (PTCL) and other licensed local loop operators for PSTN services.
Dialing Formats and Usage
For callers within Pakistan, the local dialing format is 04548 XXXXXX, where the leading 0 is the trunk prefix. When dialing from abroad, the trunk prefix is omitted, and the number is dialed as +92 4548 XXXXXX. Subscriber numbers in this area typically consist of six digits after the area code, making the total national significant number (NSN) length ten digits (including the leading 0). For example, a local number might be 04548 123456, which becomes +92 4548 123456 for international callers.
Khushab operates as a single-rate center, meaning calls within the district are charged at local rates. Calls from other cities in Pakistan require dialing the full national format with the area code. International callers must replace the trunk prefix with the country code +92.
Geographic and Administrative Context
Khushab is located in the Salt Range region of Punjab, approximately 200 kilometers northwest of Lahore. The district is known for its agricultural production and the Khushab Nuclear Complex, which is a major research facility. The area code 4548 is exclusively geographic, and its allocation is managed by the Pakistan Telecommunication Authority (PTA). As of the latest numbering plan updates, there are no overlay codes for Khushab, so 4548 remains the sole NDC for fixed-line services in the district.
For businesses and residents, it is important to note that while mobile numbers in Pakistan are non-geographic and begin with 3 (e.g., 0300, 0321), fixed-line numbers like those under 4548 are tied to the physical location. This distinction is crucial for call routing and billing purposes. When calling a Khushab number from a mobile phone within Pakistan, users should still dial the full national format (04548 XXXXXX) to ensure proper routing.
