Area Code 424 – Lahore

Geographic Overview

The area code 424 is a Geographic National Destination Code (NDC) assigned to Lahore, the capital city of Punjab province and the second-largest metropolis in Pakistan. Lahore serves as the country's cultural, educational, and industrial hub, with a population exceeding 13 million. The 424 code covers the entire Lahore District, including the central business districts (Gulberg, Liberty, and Model Town), residential areas (DHA, Bahria Town, and Johar Town), and the Allama Iqbal International Airport. It does not extend to neighboring cities such as Kasur or Sheikhupura, which maintain their own distinct area codes.

Dialing Formats

For callers within Pakistan, the national trunk prefix 0 must be dialed before the area code when calling from outside the Lahore region. The local subscriber number (SN) typically consists of 7 digits, resulting in the following format:

• National (from other Pakistani cities): 0 424 XXX XXXX
• International (from abroad): +92 424 XXX XXXX
• Local (within Lahore): 424 XXX XXXX (if supported by the operator) or simply the 7-digit subscriber number.

Example: A landline number in Lahore might be 0424 123 4567 when dialed nationally, or +92 424 123 4567 from overseas. Note that the leading 0 is omitted in international format.

Overlay and Numbering Changes

Lahore has not undergone an overlay in recent years; the 424 code remains the sole geographic code for the city. However, due to the rapid expansion of fixed-line and wireless local loop (WLL) services, the Pakistan Telecommunication Authority (PTA) has implemented number conservation measures. Subscribers may encounter 7-digit numbers that begin with digits 0 or 1, which are reserved for special services and are not part of the standard geographic numbering range.

Caller Instructions

• Local callers within Lahore can often dial the 7-digit subscriber number directly, but it is safer to include the area code to avoid misrouting.
• National callers from other cities must dial 0 followed by 424 and then the subscriber number.
• International callers should dial their country's exit code (e.g., 00 or 011), followed by Pakistan's country code 92, then 424 and the subscriber number, omitting the initial 0.

All calls to 424 numbers are routed over the PSTN and are subject to standard local or national tariffs, depending on the caller's location. VoIP users should ensure their service provider supports Pakistani geographic numbers to avoid connectivity issues.
