📍 Geographic Location of Chandigarh, Punjab
Geographic Coverage and Administrative Jurisdiction
The area code 172 is the National Destination Code (NDC) assigned to the Union Territory of Chandigarh and its surrounding regions. Chandigarh serves as the joint capital of the states of Punjab and Haryana, and the code covers the entire city of Chandigarh, including its administrative sectors, as well as the neighboring towns of Mohali (SAS Nagar) in Punjab and Panchkula in Haryana. These areas form the Chandigarh Tricity, a major urban agglomeration in northern India.
Dialing Formats and Number Structure
When dialing from within India, the trunk prefix 0 is used, followed by the area code and the local subscriber number. For example, to call a landline in Chandigarh from another Indian city, you would dial 0-172-XXXXXXX, where the local number is typically 7 digits long. Internationally, callers must use the country code for India, +91, followed by the area code without the leading zero: +91-172-XXXXXXX. For instance, a local number such as 1234567 would be dialed as +91 172 1234567 from abroad.
Overlays and Numbering Changes
As of the latest updates, the 172 area code does not have an overlay. The region continues to use the 7-digit subscriber numbering within the 172 NDC. However, with the increasing demand for telecommunication services in the Tricity area, authorities have periodically reviewed numbering resources. Subscribers should be aware that any future changes would be widely publicized, but currently, no overlay or migration is in effect.
Caller Instructions
For local callers within the 172 area code, it is possible to dial the 7-digit subscriber number directly without the area code. However, for calls from other parts of India, the full 0-172 prefix is required. International callers should replace the trunk prefix with the +91 country code. It is also important to note that while the 172 code is primarily associated with fixed-line PSTN services, some VoIP and wireless local loop services may also be assigned numbers under this code, but mobile numbers in India are exclusively under the 9x prefixes and are not affected by this geographic code.
