Area Code 427 – Lahore

Geographic Coverage and Administrative Jurisdiction

The area code 0427 is a geographic National Destination Code (NDC) assigned to the Lahore metropolitan region in Pakistan. Specifically, it serves the Lahore Division of Punjab Province, including the city of Lahore and its surrounding suburban areas. The code is administered under the Pakistan Telecommunication Authority (PTA) and follows the ITU-T E.164 international numbering plan.

Dialing Formats and Usage

For callers within Pakistan, the local dialing format is 0427-XXXXXXX (where X denotes the subscriber number). When dialing from outside Pakistan, the international format is +92 427 XXXXXXX (or +92-427-XXXXXXX). Note that the leading '0' of the area code is dropped when using the country code.

Example: To call a Lahore landline number 1234567 from abroad, dial +92 427 1234567. From within Pakistan, dial 0427 1234567.

Overlay and Numbering Considerations

Lahore has multiple area codes due to its large subscriber base. The 0427 code is one of several geographic codes serving the city; others include 042 and 0422. These codes are not overlays but distinct numbering areas within the same metropolitan region. Callers must use the correct code based on the specific exchange or locality. The subscriber number length is typically 7 digits, making the total national significant number (NSN) 10 digits (including the area code).

Caller Instructions

• Local callers (within Pakistan): Always dial the full area code plus subscriber number, even for calls within Lahore, to ensure proper routing.
• International callers: Dial your country's exit code (e.g., 00 or 011), then Pakistan's country code 92, then the area code 427 (without the leading 0), followed by the subscriber number.

This code is used exclusively for fixed-line (PSTN) services. Mobile numbers in Pakistan use non-geographic prefixes (e.g., 0300, 0311) and are not affected by this area code.
