Understanding CIN Search & Verification

Learn what a Corporate Identification Number is, where to find it, and why verifying it protects your business.

What is a CIN & Why It Matters

A Corporate Identification Number (CIN) is a unique 21-character alphanumeric code assigned by the Registrar of Companies (ROC) to every company incorporated in India under the Companies Act. It appears on the certificate of incorporation and must be quoted on official company documents such as invoices, letterheads, notices, and annual filings.

Did You Know?

Public Information: CIN details are part of the public MCA register — anyone can look up a company's CIN and registration details.
Mandatory Disclosure: Under Section 12 of the Companies Act, 2013, companies must print their CIN on all official publications and correspondence.
Not for LLPs: Limited Liability Partnerships get an LLPIN and foreign companies an FCRN instead of a CIN — our search covers all three.

Find a CIN by Company Name

Type the company name in the search bar above and pick the right match — the profile shows the full CIN with all registration details.

Verify an Existing CIN

Paste a CIN you were given and confirm it belongs to the company you are dealing with, with current status from MCA records.

Check Company Health

Company profiles include directors, charges, GSTINs, and filing activity — context a bare CIN cannot give you.

Common Use Cases for CIN Search

Vendor Onboarding

Confirm a supplier is a genuinely registered, active company before adding them to your systems.

Contract Due Diligence

Match the CIN on an agreement against the legal entity actually signing it.

Credit and Investment Checks

Review incorporation age, company type, and ROC details before extending credit or investing.

ROC Number

Example CIN: L17110MH1973PLC019786 (Reliance Industries Limited)

Listing Status (1st Character)

The first letter is 'L' for companies listed on a recognised Indian stock exchange and 'U' for unlisted companies. The vast majority of Indian companies carry a 'U'.

A vendor claiming to be "listed" whose CIN starts with 'U' deserves a closer look.

Industry Code (Next 5 Digits)

Digits 2–6 are the National Industrial Classification (NIC) code describing the company's principal business activity at incorporation — for example 17110 for textile manufacturing.

Companies can diversify over time, so treat the industry code as the activity registered with the ROC, not necessarily everything the company does today.

State Code (Next 2 Letters)

Characters 7–8 identify the state or union territory where the company is registered — MH for Maharashtra, DL for Delhi, KA for Karnataka, and so on.

This reflects the registered office location filed with the ROC, which can differ from where the company actually operates.

Incorporation Year (Next 4 Digits)

Characters 9–12 are the year the company was incorporated. A quick age check helps spot recently created entities presenting themselves as established businesses.

Company Type (Next 3 Letters)

Characters 13–15 encode the ownership classification assigned by the ROC.

PLC — Public Limited Company
PTC — Private Limited Company
FTC — Subsidiary of a Foreign Company
OPC — One Person Company
GOI / SGC — Central / State Government Company
NPL — Not-for-Profit (Section 8) Company

ROC Registration Number (Last 6 Digits)

The final six digits are the sequential registration number issued by the Registrar of Companies. Together with the rest of the code, it makes every CIN unique.

Assigned once at incorporation and never reused
Quoted in ROC filings and legal proceedings
Stays the same even if the company is renamed

Frequently Asked Questions About CIN Search & Verification

How to verify a CIN number is genuine?

Verify a CIN in three steps:

Paste the 21-character CIN into the search bar above
Check that the company name returned matches the entity you are dealing with
Review the profile for registration status, directors, and filing activity

If the CIN returns no match or a different company name, do not proceed without further checks.

What does each part of a CIN mean?

A CIN is 21 characters with a fixed structure:

1st character: Listing status — L (listed) or U (unlisted)
Next 5 digits: NIC industry code
Next 2 letters: State of registration
Next 4 digits: Year of incorporation
Next 3 letters: Company type (PLC, PTC, FTC, OPC…)
Last 6 digits: ROC registration number

See the format breakdown above for a worked example.

Is CIN the same as GSTIN or PAN?

No — they are separate identifiers issued by different authorities:

CIN: 21 characters, issued by the ROC/MCA at incorporation
PAN: 10 characters, issued by the Income Tax Department
GSTIN: 15 characters, issued under GST — it embeds the PAN

A company has one CIN but can hold multiple GSTINs across states. WeeDoo.in profiles link all of them together, and our GSTIN search covers the GST side.

Do LLPs and foreign companies have a CIN?

Not exactly — they get parallel identifiers:

LLPIN: issued to Limited Liability Partnerships
FCRN: Foreign Company Registration Number for foreign companies operating in India

The search bar above accepts company names, CINs, LLPINs, and FCRNs, so you can look up all these entity types in one place.

Can a CIN change?

Yes, in specific situations:

Listing or delisting changes the first character (L/U)
Moving the registered office to another state changes the state code
Converting between private and public changes the company-type letters

A plain rename does not change the ROC number at the end. If you hold an old CIN, search it on WeeDoo.in to find the company's current registration details.
