Chandigarh is a Union Territory and also serves as the capital for both Punjab and Haryana. Since it’s a relatively compact urban area, it has only one STD (Subscriber Trunk Dialing) code used across the city and nearby surrounding regions.
| City/Town | STD Code |
|---|---|
| Chandigarh (Main City) | 0172 |
| Manimajra | 0172 |
| Sector Zones (1 to 63+) | 0172 |
| Daria | 0172 |
| Maloya | 0172 |
| Hallomajra | 0172 |
| Sarangpur | 0172 |
| Industrial Area Phase I & II | 0172 |
| Nearby Punjab sectors (Mohali) | 0172 |
| Nearby Haryana sectors (Panchkula) | 0172 |
🔹 Note:
-
0172 is the only STD code assigned to all sectors and regions within Chandigarh.
-
Neighboring areas such as Mohali (Punjab) and Panchkula (Haryana) also use the same STD code, making the Chandigarh Tricity region unified in telecom connectivity.
