The Ministry of Corporate Affairs maintains a central database of every company and director registered in India. This database — commonly referred to as MCA master data — is the authoritative source for CIN numbers, director DINs, registered addresses, charges, and filing histories. With the launch of the MCA V3 portal, access to master data has been restructured under a new interface and set of services.
This guide explains what MCA V3 master data contains, how to access it, and how compliance teams use it in practice.
What Is MCA Master Data?
MCA master data refers to the core profile records stored in the Ministry of Corporate Affairs database for each registered entity. For a company, the master data includes:
- Corporate Identification Number (CIN) — the unique 21-character identifier assigned at incorporation
- Company name, registered address, and email
- Date of incorporation and class of company (private, public, OPC, Section 8, etc.)
- Authorised and paid-up share capital
- Current status (Active, Strike Off, Under Liquidation, etc.)
- ROC (Registrar of Companies) jurisdiction
- List of current directors and their DINs
- Charge details (creation, modification, satisfaction)
- Annual filing status (AOC-4, MGT-7/7A) for recent financial years
For directors, MCA master data includes the DIN, name, designation, nationality, and all associated companies where the individual holds a directorship.
MCA V3 vs MCA V2: What Changed for Master Data?
The MCA V3 portal (launched in phases between 2022 and 2024) replaced the older MCA21 V2 interface. The core master data is the same — the underlying database has not changed — but the way you access it has:
| Feature | MCA V2 | MCA V3 |
|---|---|---|
| Company search | Public search at separate URL | Unified under mca.gov.in/content/mca/global/en/mca/master-data.html |
| DIN lookup | Separate DIN search tool | Integrated into MCA Services menu |
| Filing history | Visible without login | Full history requires login |
| API access | Limited data API | V3 data API with auth tokens |
| Charge search | Separate charges portal | Consolidated under company profile |
On MCA V3, the term "master data" specifically appears in the portal navigation under MCA Services → Master Data — this section provides bulk and individual lookups for company and director records.
How to Log In to MCA and Access Master Data
Some master data (basic company search, DIN verification) is available without logging in. For detailed records, filing history, and charge data, you need to be signed in.
Step 1: Log In to the MCA V3 Portal
- Go to mca.gov.in
- Click Login in the top right corner
- Enter your registered business user ID and password
- Complete the OTP verification (sent to your registered mobile or email)
If you do not have an account, register under Register Business User. Company secretaries, chartered accountants, and cost accountants should register with their professional credentials (ICSI/ICAI membership number) to access filings on behalf of their clients.
Step 2: Navigate to MCA Services → Master Data
- After login, go to the top navigation bar and click MCA Services
- In the dropdown, select Master Data
- Choose the type of lookup: View Company/LLP Master Data or View DIN Master Data
You can also reach this directly by searching a company name or CIN in the search bar — the result links directly to the master data page for that entity.
Step 3: Look Up a Company's Master Data
- Select View Company/LLP Master Data
- Enter the company name, CIN, or LLPIN
- The portal displays the full company master data record: status, capital, directors, ROC, address, and recent filings
- To view charge details, click the Charges tab within the company profile
Step 4: Look Up a Director's DIN Master Data
- Select View DIN Master Data from the MCA Services → Master Data menu
- Enter the DIN (8-digit number) or the director's name
- The portal shows the director's current status, name, nationality, and a list of all current and past directorships
Which MCA Services Expose Master Data?
Several services within the MCA V3 portal draw from the same underlying master data. Knowing which service to use for which purpose saves significant time:
| What You Need | MCA Service to Use |
|---|---|
| Company status, capital, directors | MCA Services → Master Data → View Company/LLP Master Data |
| DIN status, associated companies | MCA Services → Master Data → View DIN Master Data |
| Charge search (for due diligence) | MCA Services → Charges → View Charge Details |
| Annual filing status (AOC-4, MGT-7) | MCA Services → Filing → View Public Documents |
| Director KYC status | MCA Services → Director → KYC Status Check |
| Signatory details on a form | MCA Services → e-Filing → View Processed Document |
Common Issues When Accessing MCA V3 Master Data
- Login failures: MCA V3 enforces session timeouts and single-session policies. If a colleague is logged in with the same credentials, your session may be rejected. Use separate user accounts for each professional.
- Master data not updating after a filing: After an e-Form is processed (SRN marked as Approved), master data typically refreshes within 24–72 hours. If you need updated data urgently, check the View Processed Document section — it reflects approvals sooner than the master data search.
- DIN not found: If a DIN search returns no results, the DIN may be deactivated due to missed DIR-3 KYC. A deactivated DIN does not appear in public search results. The DIN holder must file DIR-3 KYC and pay the ₹5,000 late fee to reactivate it.
- Incorrect director list: MCA master data shows directors based on approved DIR-12 filings. If a director was recently appointed or resigned and the DIR-12 SRN is still in processing, the master data will not reflect the change yet.
- CIN mismatch: If a company has undergone conversion (private to public, LLP to company, etc.), the identifier may have changed. Search by name if the CIN lookup fails.
How Compliance Software Uses MCA Master Data
The manual process of copying data from MCA master data records into forms — CIN, director names, DINs, registered address, share capital — is a significant source of errors in compliance filings. Transposing a digit in a CIN or entering a director name differently from how it appears in the MCA database causes SRN rejections that can take weeks to resolve.
Leagully connects directly to MCA V3 master data and pulls the live record for each company and director in your portfolio. When you prepare a filing on Leagully — whether it's an AOC-4, a DIR-12, or a PAS-3 — the form is pre-filled from the same master data the MCA portal uses. You review and approve; Leagully submits. No manual copying, no mismatches, no rejected SRNs from data-entry errors.
The same master data integration powers Leagully's compliance calendar: because we know each director's DIN status, each company's last annual filing date, and each pending charge, we can accurately predict your next filing deadlines and flag any data anomalies before they become SRN rejections.
MCA Master Data for Due Diligence
Beyond routine compliance, MCA master data is widely used for corporate due diligence — verifying a counterparty's existence, checking director backgrounds, and identifying undisclosed charges before signing an investment agreement or a lending facility.
Key due diligence checks using MCA master data:
- Company status verification: Confirm the company is Active and not under strike-off, winding up, or moratorium proceedings
- Director background check: Look up a director's DIN to see all current and past directorships — a director disqualified under Section 164(2) will not appear on active filings
- Charge search: Identify all registered charges (secured loans, hypothecations, mortgages) on the company's assets
- Filing compliance check: Verify that the target company has filed its annual returns and financial statements for the past 3 financial years — gaps indicate non-compliance and potential penalties
