Area Code 175 – Patiala, Punjab

Geographic Coverage and Administrative Jurisdiction

The +91 175 country calling code segment is a geographic National Destination Code (NDC) assigned to the city of Patiala in the northern Indian state of Punjab. Patiala serves as the administrative headquarters of the Patiala district and is a significant cultural and historical center within the Malwa region of Punjab. The code covers the urban agglomeration of Patiala and its surrounding suburban areas, including Rajpura, Nabha, and Samana, which are part of the Patiala district's telecommunications service area.

Dialing Formats and Caller Instructions

For callers within India, the local dialing format requires the trunk prefix 0 followed by the area code and the subscriber number. For example, to call a landline in Patiala from another Indian city, you would dial:

• 0-175-XXXXXXX (where XXXXXXX is the 7-digit local subscriber number).

For international callers, the format follows the ITU-T E.164 standard: the country code +91, the area code 175 (without the leading zero), and the 7-digit subscriber number. For instance, a caller from the United States would dial:

• 011-91-175-XXXXXXX (from a US landline) or +91-175-XXXXXXX (from a mobile phone).

It is important to note that the leading 0 is a domestic trunk prefix and must be omitted when dialing from outside India.

Overlay and Numbering Considerations

As of the current numbering plan, the 175 area code does not have an overlay code; it is the sole geographic code for Patiala. However, the rapid expansion of telecommunications services in Punjab has led to the implementation of an inter-circle mobile numbering system, but landline numbers in Patiala remain fixed to the 175 NDC. The subscriber number length is consistently 7 digits, ensuring a total of 10 digits for the complete national significant number (NSN) when combined with the area code.

Caller Instructions for Local and Foreign Callers

Local callers within Patiala can often dial the 7-digit subscriber number directly without the area code, depending on their service provider's local call policy. However, for clarity and to avoid misdialing, it is recommended to use the full national format. Foreign callers should always use the international format with the +91 country code. Additionally, when calling from a mobile phone in India, the trunk prefix 0 is generally required even for local calls, as mobile networks do not automatically add the area code.

Patiala's telecommunications infrastructure is fully integrated into the national network, supporting both PSTN and VoIP services. Callers using VoIP services should ensure they have an active international calling plan, as rates may vary. The geographic nature of the code means that calls are routed based on the physical location of the subscriber, which is essential for emergency services and regulatory compliance.
