Relocating to Mohali brings immediate address confusion. Newcomers wonder whether Mohali is part of Chandigarh or Punjab, why power bills come from PSPCL while postal codes start with 160, and why locals treat Phase 3B2 and Sector 60 as the same place.

Local real estate Instagram pages and creators are an active source of listings and area info for Tricity renters today. However, understanding property registries and postal routing requires looking at five decades of regional planning. This guide clarifies the administrative status, the historical Phase versus Sector system, and PIN code geography of SAS Nagar Mohali.

State & District Identity: Is Mohali in Chandigarh or Punjab?

Mohali is located entirely within Punjab, bordering Chandigarh along Sectors 51/52 and 53/54 to form the western wing of the Tricity (Chandigarh, Mohali, Panchkula).

The city takes its name from Mohali village near Phase 8. Following the 1966 Punjab reorganization and Chandigarh's status as a shared capital, Punjab planned an adjacent urban hub.

On 14 April 2006, Punjab carved areas from Ropar (Rupnagar) and Patiala districts to establish its 18th district, named Sahibzada Ajit Singh (SAS) Nagar after the eldest son of Guru Gobind Singh. Official documents use "SAS Nagar", while "Mohali" remains universally used in commerce, transit, and sports.

The 3 Tehsils of SAS Nagar District

SAS Nagar district comprises three administrative sub-divisions:

1. SAS Nagar (Mohali) TehsilEncompasses the urban grid from Phase 1 to 11, central sectors up to Sector 71, and GMADA hubs including Sector 82 IT City, Aerocity, and Sectors 76 to 80.
2. Kharar TehsilCovers the northwest suburban belt along NH-5. It hosts major campuses like Chandigarh University (CU Gharuan) and CGC Jhanjeri, attracting students seeking budget builder floors.
3. Dera Bassi TehsilCovers the southeast corridor bordering Haryana, including Zirakpur, Lalru, and Dera Bassi industrial clusters.

Phase vs. Sector Numbering: Why Mohali Has Both

A delivery label might read "Phase 7", while map apps show "Sector 61". Both refer to the same block. The dual names exist because Mohali developed in two successive planning eras.

Extending the Chandigarh Grid into Punjab

Le Corbusier planned Chandigarh in self-contained sectors (800m by 1,200m). The UT grid originally stopped around Sector 47, later extending to Sector 56 on the western fringe.

In the 1970s, the Punjab Urban Planning and Development Authority (PUDA) acquired land across the UT border, building residential pockets in waves called "Phases" (Phases 1 to 11).

To preserve uninterrupted road continuity and grid alignment, planners assigned Chandigarh-series sector numbers starting where the UT grid ended:

• Phase 1 became Sector 55; Phase 2 and 6 aligned with Sectors 54 and 56.
• Phase 3A mapped to Sector 53; Phase 3B1 and 3B2 became Sector 60.
• Phase 4 and 5 mapped to Sectors 59 and 58; Phase 7 became Sector 61.
• Phases 8, 9, 10, and 11 mapped to Sectors 62, 63, 64, and 65.

Residential Phases vs. Industrial Phases

Mohali also features designated Industrial Area Phases on a separate track. Industrial Area Phase 8B (housing QuarkCity and Bestech) sits in Sector 74 and 74A, not residential Phase 8 (Sector 62). Confusing industrial and residential phases misplaces an address by several kilometres.

Why GMADA Dropped "Phases" After Sector 65

In the early 2000s, the Greater Mohali Area Development Authority (GMADA) took over regional planning and discontinued "Phase" terminology. All sectors developed after Sector 65 use sector numbers exclusively: Sectors 66 to 71, Sectors 76 to 80, Sector 82 IT City, Sector 88, and onwards. Only the first eleven residential pockets carry phase names.

The table below outlines Mohali's residential phases, official GMADA sector numbers, postal PIN codes, notable landmarks, and dominant housing formats.

Decoding the PIN Code Divide: 160xxx vs. 140xxx

Mohali's postal index numbers fall into two administrative circles.

The Chandigarh Postal Division (160xxx)

Under India Post, delivery divisions reflect operational logistics rather than state borders. Early Mohali phases and Sectors 68, 70, and 71 were assigned to the Chandigarh Postal Division using the 160xxx series.

The central distribution hub is the Mohali Head Post Office in Phase 8 (Sector 62, PIN 160062). Sub-post offices manage specific sectors: Phase 1 (160055), Phase 4 and 5 (160059), Phase 7 (160061), and Sectors 70 and 71 (160071).

The Punjab Regional Postal Division (140xxx)

Newer GMADA sectors, IT City, and Aerocity fell under the Punjab postal circle, using the 140xxx series tied to Ropar and Patiala sorting hubs.

As a result, Sector 82 IT City, JLPL Industrial Area, and Aerocity use PIN 140306, handled by the Aerocity Sub-Post Office. Sectors 76 to 80 and Sector 88 route mail through 140308. Meanwhile, Kharar uses 140301, and Dera Bassi uses 140507.

Civic Amenities: Mohali (Punjab) vs. Chandigarh (UT) vs. Panchkula (Haryana)

While travel across the Tricity is physically uninterrupted, civic amenities and rules diverge across state borders.

Rental Guidelines & Legal Compliance in SAS Nagar

Tenants and landlords in Mohali must comply with Punjab administrative regulations:

1. Mandatory Tenant Police Verification

Tenant police verification is mandatory across SAS Nagar district under District Magistrate orders issued under Section 163 of the BNSS. Landlords failing to submit tenant records face penalties under Section 223 of the BNS. Verification can be completed online via the Punjab Police Saanjh portal (ppsaanjh.in) or at a local Saanjh Kendra (Phase 8 or Sector 70) for a statutory fee of ₹200.

2. Security Deposit Regulations

There is no statutory security-deposit cap anywhere in the Tricity. The two-month cap reported in 2026 stemmed from a Chandigarh Administration notification of the Assam Tenancy Act, 2021 (notified 6 May 2026). On 29 May 2026, the Punjab & Haryana High Court stayed that notification, keeping it in complete abeyance. Chandigarh remains governed by the East Punjab Urban Rent Restriction Act, 1949, and Panchkula by the Haryana Urban (Control of Rent and Eviction) Act, 1973. Mohali follows Punjab tenancy provisions, where security deposits are contractual. In current market practice, landlords conventionally ask for one to two months of rent as a deposit.

3. IT Corridor Housing Dynamics

Professionals working in QuarkCity Phase 8B or IT City Sector 82 choose between established builder floors in Sectors 70 and 71 and gated apartments on Airport Road. For society move-in fees and co-living guidelines, read our guide to co-living rules and society guidelines for IT professionals in Mohali Phase 8B and Sector 82.

Frequently Asked Questions

Is Mohali located in Chandigarh or in Punjab?

Mohali is situated entirely in Punjab, not the Union Territory of Chandigarh. While it borders Chandigarh and shares an integrated road grid as part of the Tricity region, Mohali is an independent district capital governed by the Government of Punjab and Municipal Corporation SAS Nagar.

How do Mohali Phases map to Sector numbers?

Mohali's residential Phases 1 through 11 map directly to Chandigarh master plan Sectors 55 through 65. For example, Phase 1 is Sector 55, Phase 3B2 is Sector 60, Phase 7 is Sector 61, and Phase 11 is Sector 65. GMADA sectors developed after Sector 65 use sector numbers exclusively.

Why do some Mohali PIN codes start with 160 while others begin with 140?

Mohali has two postal circles. Older residential phases (Phases 1–11) and central sectors (68, 70, 71) fall under the Chandigarh Postal Division using 160xxx PIN codes. Newer GMADA developments like Sector 82 IT City and Aerocity belong to the Punjab postal circle using 140xxx PIN codes.
