Chennai Corporation Zones Explained: Current 15 and Proposed 20
What we know
Summary
Chennai, July 2026 — Two zone maps keep circulating online: a 2022 concept for 23 Corporation zones, and a 2025 state announcement for 20 zones. Neither is how GCC currently presents itself to the public.
Official ward-map selectors, councillor directories and zonal services continue to list Zones 1–15 — from Thiruvottiyur to Sholinganallur — with 200 wards. Mayor R. Priya has linked 20-zone implementation to the end of the present council tenure (around 2027). In May 2026, the Commissioner described the increase as a government policy decision still awaiting operationalisation.
Current 15-zone ward list
| Zone | Name | Wards |
|---|---|---|
| 1 | Thiruvottiyur | 1–14 |
| 2 | Manali | 15–21 |
| 3 | Madhavaram | 22–33 |
| 4 | Tondiarpet | 34–48 |
| 5 | Royapuram | 49–63 |
| 6 | Thiru-Vi-Ka Nagar | 64–78 |
| 7 | Ambattur | 79–93 |
| 8 | Anna Nagar | 94–108 |
| 9 | Teynampet | 109–126 |
| 10 | Kodambakkam | 127–142 |
| 11 | Valasaravakkam | 143–155 |
| 12 | Alandur | 156–167 |
| 13 | Adyar | 170–182 |
| 14 | Perungudi | 168, 169 and 183–191 |
| 15 | Sholinganallur | 192–200 |
Note: Zone 14 (Perungudi) holds wards 168–169 and 183–191; Zone 13 (Adyar) holds 170–182. Do not infer zone only from ward order.
What the three maps mean
- Current 15 zones — live for offices, wards committees and complaints.
- Approved 20 zones (2025) — planned redistribution of population, properties, roads and staff; not yet in public GCC systems.
- 23-zone concept (2022) — superseded Assembly-alignment idea; do not use for current addresses.

What this means in Chennai
Local impact, institutions, and what residents should watch next.
Why this matters
Changing a Corporation zone is not cosmetic. Each zone functions as a wards committee with a zonal office coordinating engineering, sanitation, public health, revenue and local council work. Implementation needs gazette notification, office locations, staff deployment, software updates and coordinated transition — often tied to the civic election cycle.
Editorial note
This MyChennaiCity guide distinguishes the operational 15-zone system from the approved 20-zone plan and the historical 23-zone proposal. Figures for the proposed 20-zone map are drawn from contemporaneous reporting and should be treated as reported proposal data, not current GCC zone statistics. Always prefer the latest gazette notification and the official GCC portal when records conflict.

FAQ
No. The 23-zone map belongs to a proposal reported in 2022. It is not the present operational map.
