How to track the CIN of your company
There are two ways to find the CIN of any Indian company: through the company’s official documents or by searching on the MCA portal online.
Method 1 — Check official company documents:
The CIN is printed on all official company documents by law. You can find it on:
- Certificate of Incorporation (issued at the time of registration)
- Company invoices, bills, or receipts
- Company letterhead
- Annual reports
- The footer of the company’s official website
Method 2 — Search on the MCA portal (step by step):
- Go to the official MCA portal: www.mca.gov.in
- Navigate to: MCA Services → Company/LLP Master Data, or use: https://mca.gov.in/mcafoportal/findCIN.do
- Select the entity type: Choose “Company” or “LLP” from the dropdown menu
- Enter search details: You can search using the Registration Number, Current Company Name, Inactive CIN, or Previous Company Name
- Complete the CAPTCHA verification
- Click on “Search” — the CIN and basic company details will be displayed in the results
Tip: If you are verifying a company before entering into a business deal, loan agreement, or supplier contract, always cross-check the CIN on the MCA portal. This helps confirm that the company is active, legally registered, and not subject to any regulatory action.
CIN requirement for GST registration
The CIN (Corporate Identification Number) is a mandatory requirement for GST registration for companies. Here is why it is required and how it is used in the GST process:
- Verification of legal existence: GST authorities require the CIN to confirm that the applicant is a legitimately incorporated company under the Companies Act, 2013, and not an unregistered or fraudulent entity.
- Business identity confirmation: The CIN links the GST registration to a specific company in the MCA records, ensuring that the GSTIN is issued to the correct legal entity.
- Director and officer linkage: GST registration for companies includes director details, which are cross-verified against MCA records associated with the CIN, helping to prevent false or incorrect KYC submissions.
- Compliance tracking: Tax authorities use the CIN to cross-check a company’s GST filings (such as GSTR-1 and GSTR-3B) with its MCA filings, helping to identify inconsistencies that may indicate non-compliance or tax evasion.
- Linkage for MSME and business loans: Companies that complete GST registration using their CIN can use their GSTIN as supporting documentation when applying for MSME loans, start-up funding, and working capital finance from lenders such as Bajaj Finserv.

Under Section 12(3)(c) of the Companies Act, 2013, every company must display its CIN on all official documents and communications. Failure to do so attracts a penalty of Rs. 1,000 per day, subject to a maximum of Rs. 1,00,000. Here is where the CIN must mandatorily appear:

Breaking down CIN number
CIN (Corporate Identification Number) is a unique 21-character code, divided into six sections, each representing specific details about a company. Here’s an example:
L12345RJ2024PLC087432
- L: Listing Status
- 12345: Industry Code
- RJ: State Code
- 2024: Year of Incorporation
- PLC: Type of Company
- 087432: Registration Number
Explanation of each section:
- Listing Status: ‘L’ indicates a listed company, while ‘U’ is for an unlisted company.
- Industry Code: A 5-digit number that identifies the industry of the company, assigned by the Registrar of Companies (ROC).
- State Code: Shows the state where the company is registered.
- Year of Incorporation: Indicates the year the company was incorporated.
- Type of Company: Represents the ownership type, such as Private Limited, Public Limited, Government, Non-profit, or One-person Company.
- Registration Number: The unique number assigned to the company during registration.
Required usage of CIN in corporate documentation
Under the Companies Act, 2013, Section 12(3)(c), every company is legally required to display its CIN on all official documents, letterheads, and company communications. This is not optional — it is a statutory compliance requirement enforced by the Ministry of Corporate Affairs (MCA).
Complete list of documents where CIN must be displayed:
- Receipts, invoices, and bills (all payment-related documents)
- Official letterheads (both printed and digital)
- Company notices, memoranda, and internal circulars
- Annual reports and financial statements
- Audit reports and board reports
- All e-forms and returns filed on the MCA portal
- External emails (CIN must be included in the email signature or footer)
- Publications such as journals, books, and financial results published in newspapers
- All formal communications and regulatory submissions
- Business loan applications and banking documents
- GST filings and GST registration documents
Penalty for non-compliance of mentioning CIN
Not displaying your CIN on official documents constitutes a violation of Section 12 of the Companies Act, 2013. The penalty structure is as follows:
| Violation | Penalty on company | Penalty on each responsible officer | Maximum cap |
|---|
| Failure to display CIN on official documents | Rs. 1,000 per day of default | ₹1,000 per day of default (per officer) | Rs. 1,00,000 in total (for the company and for each officer) |
| Incorrect or false CIN displayed | Treated as misrepresentation; subject to additional penalties under Section 447 | Directors may be held personally liable for misrepresentation | Penalties may extend up to three times the amount of any wrongful gain under fraud provisions |
| CIN missing from MCA portal filings | Filing may be rejected; resubmission required | The officer responsible for filing may be held personally liable | Delay penalties apply in accordance with MCA filing regulations |
Practical advice:
Set up a compliance checklist to ensure that the CIN appears on all letterheads, invoice templates, email signatures, and MCA filing templates. Updating your templates once can help avoid ongoing exposure to daily penalties.
When to update the Corporate Identification Number (CIN)
A CIN is generally permanent; however, certain structural changes to a company require an update to reflect its revised corporate status. Here are the situations in which a CIN change is triggered:
| Trigger event | Which part of CIN changes | Process required |
|---|
| Company shifts its registered office to another State | Section 3 (State code) changes | File Form INC-23 with the National Company Law Tribunal (NCLT) for approval; the Registrar of Companies (RoC) in the new State issues an updated CIN |
| Company converts from a private limited to a public limited company (or vice versa) | Section 5 (company type code) changes (e.g., PTC to PLC) | File Form INC-27 for conversion; the RoC updates the CIN upon approval |
| Company gets listed on a stock exchange | Section 1 (listing status) changes from ‘U’ to ‘L’ | The Ministry of Corporate Affairs (MCA) updates the CIN automatically upon confirmation from SEBI |
| Company gets delisted from a stock exchange | Section 1 changes from ‘L’ to ‘U’ | The MCA updates the CIN automatically upon confirmation from SEBI |
| Company changes its primary industry or NIC code | Section 2 (industry code) changes | Apply to the RoC for a change in NIC code; the CIN is updated accordingly |
| Change in RoC jurisdiction | Section 3 (state code) may be affected | Triggered by an inter-State transfer of the registered office; requires approval from the NCLT |
Important: A change in CIN does not affect a company’s existing contracts, GST registration, PAN, bank accounts, or ongoing legal obligations. All such records remain valid and are linked to the company’s PAN and legal identity.

| Source | How to access | What you get | Free / paid |
|---|

Difference between CIN and LLPIN
CIN and LLPIN are both unique identification numbers issued by the Registrar of Companies (RoC) under the Ministry of Corporate Affairs (MCA), but they apply to different types of business entities governed by different laws. Here is a complete comparison:
| Comparison parameter | CIN | LLPIN |
|---|
| Full form | Corporate Identification Number | Limited Liability Partnership Identification Number |
| Applicable entity type | All companies incorporated under the Companies Act, 2013 | Limited Liability Partnerships (LLPs) under the LLP Act, 2008 |
| Length | 21 characters (alphanumeric) | 7 characters (alphanumeric) |
| Format | [L/U][5-digit industry code][2-letter State code][4-digit year][3-letter company type][6-digit registration number] | Typically [3 letters]-[4 digits], e.g., AAB-1234 |
| Issued by | Registrar of Companies (RoC) | Registrar of Companies (RoC) |
| Governing law | Companies Act, 2013 and MCA regulations | LLP Act, 2008 and MCA regulations |
| Information encoded | Contains details such as listing status, industry, State, year, company type, and registration number | Does not encode detailed information; it is a sequential identifier |
| Publicly searchable | Yes — via the MCA portal | Yes — via the MCA portal under the LLP section |
| Required on documents | Yes — must appear on all company letterheads, invoices, and statutory filings | Yes — must appear on all LLP letterheads, invoices, and statutory filings |
| Example | L65191MH1994PLC084688 (HDFC Bank) | AAB-1234 |
Key rule:
If you have registered a Private Limited Company, Public Limited Company, One Person Company, or Section 8 company, you will have a CIN. If you have registered a Limited Liability Partnership (LLP), you will have an LLPIN, not a CIN. Both are mandatory identifiers for their respective entity types.
Conclusion
A CIN number is not just a compliance requirement — it is the foundational identity code that defines your company's existence in the Indian regulatory ecosystem. From the day of incorporation to every GST filing, loan application, vendor contract, and investor interaction, your CIN is the reference point that proves your company is a legitimate, registered legal entity.
Key takeaways: Every Indian company (Pvt Ltd, OPC, PLC, Section 8, Government) receives a unique 21-character CIN at incorporation. CIN must appear on all official documents — letterheads, invoices, emails, MCA filings. Non-compliance attracts Rs. 1,000/day penalty (max Rs. 1,00,000). CIN is publicly searchable on the MCA portal — enabling transparent corporate verification. LLPs receive LLPIN (7 digits), not CIN — a different identifier under a different law.
