Area Code 225 – Hyderabad

Geographic Overview

The +92 225 area code is a geographic National Destination Code (NDC) assigned to the Hyderabad region in the Sindh province of Pakistan. Hyderabad, located on the east bank of the Indus River, is a major urban center and the administrative capital of Hyderabad Division. The area code covers the city of Hyderabad and its surrounding districts, including Latifabad, Qasimabad, and the industrial zones. As a fixed-line code, it is used by Pakistan Telecommunication Company Limited (PTCL) and other licensed local loop operators for PSTN and VoIP services.

Dialing Formats

When calling a Hyderabad landline from within Pakistan, subscribers must dial the national trunk prefix 0, followed by the area code 225, and then the 7-digit subscriber number. The national format is: 0 225 XXX XXXX. For international callers, the country code +92 replaces the trunk prefix, resulting in: +92 225 XXX XXXX. For example, a local number 1234567 would be dialed as 0225 1234567 domestically and +92 225 1234567 from abroad.

Caller Instructions

• Local callers: If you are within the Hyderabad area code, you may dial the 7-digit subscriber number directly, but it is always safe to use the full national format (0 225 XXX XXXX) to avoid issues with number portability or overlapping service areas.
• National callers from other cities: Dial 0 225 XXX XXXX.
• International callers: Dial your country's international access code (e.g., 00 from most countries), then 92 225 XXX XXXX (omit the leading 0).

Regulatory and Technical Notes

Pakistan's numbering plan follows ITU-T E.164 recommendations. The 225 code is a geographic code, meaning it is tied to a physical location. However, with the advent of number portability, a fixed-line number may be reassigned to a different operator, but it remains geographically associated with Hyderabad for routing purposes. The subscriber number length is 7 digits, making the total national significant number (NSN) 10 digits (including the area code but excluding the trunk prefix).

For businesses and residents, it is important to note that calls to Hyderabad landlines are typically charged at local or national rates depending on the caller's location. VoIP users should ensure their service provider supports calls to Pakistani geographic numbers and may need to configure dialing prefixes accordingly.
