Area Code 4579 – Pakpattan

Overview of Area Code +92 4579

Area code 4579 is a geographic National Destination Code (NDC) assigned to the Pakpattan region in the Punjab province of Pakistan. It is part of the country's E.164 numbering plan under the country calling code +92. The code serves the administrative district of Pakpattan, including the city of Pakpattan and its surrounding rural areas. The district is historically significant, known for the shrine of Baba Farid, and is located in the southern part of Punjab, bordered by Sahiwal, Okara, and Bahawalnagar districts.

Geographic Coverage and Dialing Formats

The 4579 area code covers the entire Pakpattan District, which is subdivided into tehsils such as Pakpattan City, Arifwala, and Mailsi (partially). The primary exchange serves the urban center of Pakpattan, while smaller exchanges in nearby towns and villages fall under the same NDC. Subscriber numbers within this area code are typically 7 digits long, resulting in a total national significant number (NSN) length of 10 digits when combined with the area code.

For local callers within Pakpattan, the number is dialed as a 7-digit subscriber number without the trunk prefix or area code. For calls from other cities within Pakistan, the format is:

• Dial the national trunk prefix 0, followed by the area code 4579, and then the 7-digit subscriber number.
• Example: 0 4579 XXXXXXX (where XXXXXXX is the local number).

For international callers, the format is:

• Dial the international access prefix (e.g., 00 from most countries), followed by Pakistan's country code 92, then the area code without the leading trunk prefix, and the subscriber number.
• Example: +92 4579 XXXXXXX.

Overlay and Numbering Considerations

Currently, there is no overlay code for Pakpattan; the 4579 code is the sole geographic code for the district. However, as with many regions in Pakistan, the Pakistan Telecommunication Authority (PTA) has implemented number portability for fixed lines, allowing subscribers to retain their numbers when switching service providers. This does not change the geographic association of the code but may affect routing for some calls.

Caller Instructions

Local callers within Pakpattan should dial only the 7-digit subscriber number. Domestic callers outside the area must include the trunk prefix 0 before the area code. International callers must omit the trunk prefix and use the country code +92. For example, to call a fixed line in Pakpattan from the United States, one would dial 011 92 4579 XXXXXXX. From the United Kingdom, it would be 00 92 4579 XXXXXXX.

It is important to note that while most numbers in the district are fixed-line PSTN connections, some VoIP services may be assigned numbers with this area code, but they are still routed as geographic numbers. Always confirm the correct number length and dialing format with your service provider if you encounter issues.
