Area Code 579 – Attock

Geographic Overview

The +92 579 numbering block is a geographic National Destination Code (NDC) assigned to the Attock region in the Punjab province of Pakistan. Attock is a historic city and district located on the banks of the Indus River, approximately 80 kilometers northwest of the federal capital, Islamabad. The code serves the administrative and commercial hubs of Attock City, Attock Khurd, and the surrounding tehsils, including Hazro, Fateh Jang, Pindi Gheb, and Jand. This area is an important industrial and agricultural zone, with significant cement, textile, and agricultural processing facilities.

Dialing Formats

For callers within Pakistan, the local dialing format for Attock numbers is 0 579 XXX XXX (where X represents the subscriber's 7-digit local number). The leading '0' is the national trunk prefix used to access the PSTN network within the country. For international callers, the format changes to +92 579 XXX XXX, omitting the leading zero. For example, a local call to a number in Attock would be dialed as 0579 1234567, while an international caller would dial +92 579 1234567.

Calling Instructions

• Local callers (within Pakistan): Dial the full national number including the trunk prefix: 0 579 XXX XXX.
• International callers: Dial your country's international access code (e.g., 011 from the US, 00 from most European countries), followed by Pakistan's country code 92, then the NDC without the leading zero (579), and the subscriber number: +92 579 XXX XXX.

Network and Regulatory Notes

Like all fixed-line geographic codes in Pakistan, the 579 prefix is allocated to the Pakistan Telecommunication Company Limited (PTCL) and other licensed fixed-line operators. The Pakistan Telecommunication Authority (PTA) oversees the allocation and management of the national numbering plan. Subscriber numbers under this NDC are typically 7 digits long, resulting in a total national significant number (NSN) length of 10 digits (including the NDC).

In recent years, Pakistan has been migrating its legacy PSTN infrastructure to Next-Generation Networks (NGN), which allows for more flexible routing and service provisioning. However, the geographic significance of the 579 code remains, and it is still used to identify the Attock area for both voice and fax services. Callers should be aware that while fixed-line numbers are generally associated with a physical location, the advent of number portability may allow some numbers to be reassigned to different operators, though the geographic association is retained for routing purposes.
