Area Code 429 – Lahore

Overview of Area Code 429 (Lahore)

Area code 429 is a geographic National Destination Code (NDC) assigned to the city of Lahore, the capital of Punjab province and the second-largest city in Pakistan. This code is part of the country's E.164 numbering plan, managed by the Pakistan Telecommunication Authority (PTA). It is used for landline (PSTN) and fixed wireless services within the Lahore metropolitan area.

Geographic Coverage and Administrative Jurisdiction

The 429 code covers the Lahore District, including its central urban zones and surrounding suburban areas. Key localities served include Gulberg, DHA (Defence Housing Authority), Model Town, Johar Town, and the historic Walled City. The code is administered under the Punjab region, with local exchanges operated by Pakistan Telecommunication Company Limited (PTCL) and other licensed fixed-line operators.

Dialing Formats and Instructions

For local callers within Pakistan: Dial the trunk prefix 0, followed by the area code 429, and then the subscriber number. The local subscriber number length typically ranges from 7 to 8 digits, depending on the exchange. The complete national format is: 0 429 XXX XXXX.

For international callers: Dial your country's exit code (e.g., 00 or +), then Pakistan's country code 92, followed by the area code 429 (without the leading zero) and the subscriber number. The international format is: +92 429 XXX XXXX.

Example: To call a Lahore landline number 1234567 from abroad, you would dial +92 429 1234567.

Overlay and Numbering Considerations

Lahore is also served by area code 42 for landlines, which was the original code. The 429 code is used for newer fixed-line services and some wireless local loop (WLL) operators. There is no overlay in the traditional sense; both codes coexist, and callers must use the correct code for the specific line. When dialing within Lahore, you must always include the area code, even for local calls, as the city uses a closed numbering plan.

Caller Instructions

• Local callers (within Lahore): Always dial 0 429 followed by the subscriber number, even if the call is to the same exchange.
• Callers from other cities in Pakistan: Dial 0 429 followed by the subscriber number.
• International callers: Dial +92 429 followed by the subscriber number, omitting the leading zero.

Ensure you have the correct subscriber number length, as it may vary. If you experience issues, confirm the number with the recipient, as mobile numbers in Pakistan use different prefixes (e.g., 3XX) and are not part of this geographic code.
