Area Code 4594 – Mianwali

Overview of Area Code +92 4594

Area code 4594 is a geographic National Destination Code (NDC) assigned to the Mianwali district in the Punjab province of Pakistan. It is part of the national numbering plan under ITU-T E.164, with the full international dialing format +92 4594 XXX XXX (or +924594XXXXXX). The code serves the administrative city of Mianwali and its surrounding rural areas, including towns such as Piplan, Rokhri, and Kacha. As a fixed-line code, it is used by Pakistan Telecommunication Company Limited (PTCL) and other licensed local loop operators for PSTN and VoIP-based landline services.

Geographic Coverage and Jurisdiction

The 4594 code covers the entire Mianwali District, which is located in the northwestern part of Punjab, bordering Khyber Pakhtunkhwa. The district is divided into three tehsils: Mianwali, Piplan, and Isakhel. Subscriber numbers under this code are typically seven digits long, but the total length of a national significant number (NSN) is ten digits (including the leading '0' when dialed domestically). For example, a local number might be 0459 456789 when dialed within Pakistan, and +92 459 456789 from abroad.

Dialing Formats and Instructions

• Local dialing (within Mianwali): If you are calling from another fixed line within the same exchange area, you may only need to dial the seven-digit subscriber number (e.g., 456789). However, due to varying local practices, it is safer to use the full national format.
• National long-distance dialing (from other cities in Pakistan): Dial 0 459 456789. The leading '0' is the trunk prefix, followed by the area code (459) and the subscriber number. Note that the area code is often written as 459, but when combined with the leading '0' for domestic calls, it becomes 0459. For international callers, the '0' is omitted.
• International dialing (from outside Pakistan): Dial your country's exit code (e.g., 00 or +), then Pakistan's country code 92, followed by the area code without the leading '0' (459) and the subscriber number. For example, to call a number in Mianwali from the US, you would dial 011 92 459 456789.

Overlays and Numbering Changes

As of the latest ITU-T operational bulletin, there is no overlay code for the Mianwali area. The 4594 code is exclusive to the district, and no recent changes have been made to the numbering plan. However, with the growth of fixed-line and VoIP services, the Pakistan Telecommunication Authority (PTA) may introduce additional digits or overlay codes in the future. Always verify the number with the recipient if you encounter difficulties.

Practical Tips for Callers

• When calling from a mobile phone in Pakistan, you must include the trunk prefix '0' even if you are in the same city, as mobile networks require the full national number.
• For international callers, ensure you have the correct country code (92) and drop the leading '0' from the area code.
• If you are using VoIP services, be aware that some providers may require the number in international format (+92 459 ...) to route correctly.
