This guide explains what a CIN number is, how to read and locate one, and why verifying a company’s CIN is important before you share personal details with any lender. It also clarifies how a CIN differs from a PAN, GSTIN and LLPIN.
A CIN, or Corporate Identification Number, is a unique 21-character code assigned by the Registrar of Companies (RoC) to every company incorporated in India under the Companies Act, 2013. If you’ve wondered “what is a CIN number” in company records, this is it. Every CIN issued in India follows the same fixed pattern and remains associated with the company for its lifetime.
You will commonly find the CIN on the Certificate of Incorporation, on invoices and letterheads, and often in a website’s footer. Checking a company’s CIN on the Ministry of Corporate Affairs (MCA) portal takes under a minute and is a sensible step before sharing sensitive information with a lender.

Why Does a CIN Number Matter?
A CIN confirms that a business exists as a legal entity separate from its owners and managers. A registered company can enter into contracts, borrow funds and be sued in its own name. Section 12(3) of the Companies Act, 2013 requires every company to display its CIN, name, registered office address, phone number and email on all invoices, letters and notices. Omission of these details may indicate oversight or deliberate concealment, either of which should raise concerns.
Spotting a Fake Lending App Using CIN
For example, a small business owner received a loan offer through an unfamiliar app. Before sharing Aadhaar and bank details, he checked the CIN listed in the app’s terms on the MCA portal. The registered company name did not match the app’s branding and the address was a residential flat. He also checked the Reserve Bank of India (RBI) list of registered NBFCs and found no record of the lender, so he declined the offer.
PRO TIP
Quick check: visit mca.gov.in, open MCA Services, select “View Company/LLP Master Data” and paste the CIN. Results appear in seconds.
Legal Context and Who Needs a CIN
The CIN requirement comes from the Companies Act, 2013. Section 7 covers CIN allotment by the jurisdictional RoC office, while Section 12(3) mandates display of the CIN on official documents. Every private limited company, public limited company, One Person Company (OPC), Section 8 non-profit, government company and Nidhi company must have a CIN. Limited Liability Partnerships (LLPs) are the exception; they are registered under the LLP Act, 2008 and receive an LLPIN instead.
You do not apply separately for a CIN. The RoC assigns the number automatically when the Certificate of Incorporation is issued.
WATCH OUT
Do not confuse a CIN with an LLPIN, PAN, GSTIN or a director’s DIN (Director Identification Number). Each identifier serves a different regulatory purpose and cannot replace another.

Where to Find a Company’s CIN Number
- Start with the Certificate of Incorporation — the CIN is printed there in full.
- If that is not available, check invoices, the company letterhead or the website footer; displaying the CIN in these locations is a legal requirement.
- If you still cannot find it, search the MCA portal using the company’s name.
How to Verify a CIN Number on the MCA Portal?
- Go to mca.gov.in and open the MCA Services menu.
- Select “View Company/LLP Master Data” under Master Data.
- Enter the CIN or the company name if you don’t have the CIN, complete the captcha and submit.
- Cross-check the company name, status, incorporation date and registered address against the information the business has provided.

DID YOU KNOW?
A student verified an employer’s CIN on the MCA portal before sharing bank details for stipend transfer and confirmed it matched the non-profit named in the offer letter.
Limitations of CIN — What It Does Not Tell You
A valid CIN confirms legal registration and the company’s recorded status, but it does not provide information about financial health, service quality, creditworthiness or licensing for regulated activities. For lending businesses in particular, incorporation alone is not sufficient; lenders should verify RBI registration for NBFCs or other required licences. Reviewing a Key Fact Statement for any loan offer adds an extra layer of protection.
