Area Code 214 – Karachi

Overview of Area Code +92 21 4

Area code 214 is a geographic National Destination Code (NDC) within the +92 country code of Pakistan. It is assigned to the Karachi metropolitan region, the largest city and economic hub of Pakistan. In the international E.164 format, the number is written as +92 21 4XXX XXXX, where +92 is the country calling code, 21 is the primary NDC for Karachi, and the following 4 is the first digit of the subscriber number, indicating a specific central office exchange within the city.

Geographic Coverage and Administration

The 214 prefix is part of the Karachi telephony network, administered by the Pakistan Telecommunication Authority (PTA). It serves both residential and business lines in the city, including areas such as Saddar, Clifton, Gulshan-e-Iqbal, and the industrial zones. The prefix is used for fixed-line PSTN services, and with the expansion of fiber and VoIP, it may also route to fixed wireless or IP-based lines that are registered to a physical address in Karachi.

Dialing Formats and Instructions

• Local dialing (within Karachi): Dial 214XXXXXX (7 digits after the trunk prefix). For example, if the number is +92 21 4123 4567, local callers dial 2141234567.
• National dialing (from other cities in Pakistan): Dial 0 21 4XXXXXX. The leading 0 is the trunk prefix used to access the national network.
• International dialing (from abroad): Dial your country's exit code (e.g., 00 or +), then 92 21 4XXXXXX. Do not include the trunk prefix 0.

Overlay and Numbering Considerations

Karachi has multiple NDCs, including 21, 22, and 23, but 21 is the primary and most widely used. The 214 prefix is not an overlay; it is a direct exchange code within the 21 NDC. However, due to the high demand for numbers, the PTA has implemented number conservation measures, and some new lines may be assigned with different initial digits after the NDC. Always verify the complete number before dialing, as mobile numbers in Pakistan are 10 digits and begin with 3 (e.g., 0300-1234567) and are not part of the 214 prefix.

Caller Instructions

For local callers in Karachi, the 214 prefix is dialed as part of the 7-digit subscriber number. For callers outside Karachi but within Pakistan, the full national format 021 4XXXXXX is required. International callers must use +92 21 4XXXXXX. Be aware that some VoIP services may require an additional access code, but standard PSTN lines follow the above formats.
