- Mumbai City (the island city — Colaba to Mahim/Sion) and Mumbai Suburban (Bandra to Dahisar/Mulund) are two separate administrative districts, each with their own Collector and revenue machinery.
- Both districts use the Property Card system rather than the 7/12/8A framework used in the rest of Maharashtra, since Mumbai’s land records were urbanized and City Surveyed much earlier than most of the state.
- Despite using the same Property Card format, some administrative processes, ward jurisdictions, and specific record-keeping details differ between the two districts.
- Buyers should confirm which district a property falls under, since that determines which Collector’s office, City Survey office, and specific ward-level record system applies.
- Mumbai Suburban, being more recently developed than the island city in many pockets, has a mix of long-settled Property Card records and some newer developments still working through initial documentation.

Mumbai City and Mumbai Suburban are two distinct administrative districts within Greater Mumbai, each with its own Collector, and while both use the Property Card system for land records, the practical administration of these records differs between them. For a buyer, this matters mainly at the level of knowing which office to approach, and understanding that “Mumbai” isn’t administratively a single homogenous unit when it comes to land record verification.
Mumbai City vs Mumbai Suburban: The Basic Split
| District | Approximate Coverage |
|---|---|
| Mumbai City | The original “island city” — Colaba, Fort, Marine Lines, Byculla, Parel, Dadar, Mahim, Sion |
| Mumbai Suburban | Bandra through Dahisar on the western side, and Kurla through Mulund on the eastern/central side |
Both districts fall under Greater Mumbai and are governed civically by the same BMC/MCGM for municipal services and property tax, but they are separate revenue districts for land record purposes, each with a distinct Collector’s office.
Why Both Use the Property Card System
Unlike most of rural and semi-urban Maharashtra, which uses the 7/12 extract and 8A framework under the standard revenue survey system, Mumbai’s land was subjected to a formal City Survey much earlier due to its dense, urbanized development history. As a result, both Mumbai City and Mumbai Suburban districts use Property Cards (CTS-number-based records) instead of the 7/12/Gat-number system — the same core reform now being extended statewide (see our guide on the 2026 7/12-to-Property Card transition).
Where the Two Districts Differ in Practice
- Separate Collector offices. Mumbai City and Mumbai Suburban each have their own District Collector responsible for revenue administration, which affects where certain applications (like Property Card corrections) need to be filed.
- Ward-level record variation. Since Mumbai Suburban includes areas that urbanized more recently than the island city, some pockets have a mix of older, well-settled Property Card records and newer developments where documentation is still catching up.
- CTS number ranges. CTS (City Survey/Cadastral Town Survey) numbers are assigned within each district’s own numbering system, so the same CTS number format doesn’t uniquely identify a property without also specifying the district and division.
“Buyers moving between Mumbai City and Mumbai Suburban properties sometimes assume the record system and process will be identical everywhere in Mumbai. The Property Card format is the same, but which Collector’s office you deal with, and how quickly a correction or query gets resolved, can differ. Confirm the district and division specifically for the property you’re evaluating.” — Girish Chhalwani, Founder & CEO, THE EDGE Developments
How to Check Which District a Property Falls Under
The Property Card itself will specify the district (Mumbai City or Mumbai Suburban), division, and CTS number. If uncertain from available documents, the area/locality name is usually a reliable indicator — anything from Bandra northward is Mumbai Suburban; anything from Mahim/Sion southward is Mumbai City — though boundary-adjacent properties should be confirmed directly.
FAQ
What’s the difference between Mumbai City and Mumbai Suburban districts?
They are two separate administrative revenue districts within Greater Mumbai — Mumbai City covers the original island city area, while Mumbai Suburban covers the areas from Bandra/Kurla northward.
Do both districts use the same land record system?
Yes, both use the Property Card (CTS-based) system rather than the 7/12 extract used in the rest of Maharashtra, since Mumbai underwent an earlier City Survey.
Why does it matter which district my property is in?
Each district has its own Collector’s office responsible for revenue administration, which affects where Property Card corrections or queries need to be filed.
How do I know if my property is in Mumbai City or Mumbai Suburban?
The Property Card specifies the district directly; as a general guide, areas from Mahim/Sion southward fall under Mumbai City, and Bandra northward falls under Mumbai Suburban.
Is the CTS number system the same across both districts?
CTS numbers are assigned within each district’s own numbering system, so the same number format requires the district and division to uniquely identify a property.
Are property tax rates different between Mumbai City and Mumbai Suburban?
Both fall under the same BMC/MCGM for municipal property tax purposes, though actual tax amounts vary by locality-specific factors like Ready Reckoner rate and usage category, not by district designation alone.
