How to read a CIN: what those 21 characters tell you
A Corporate Identity Number isn't a random string. Each block of it tells you something real about a company, before you open a single filing.

Most people treat a CIN as a reference code to copy and paste. It’s considerably more useful than that.
Think of it the way you’d think of a vehicle registration plate. It looks like noise. It isn’t. Someone who knows the format can glance at it and tell you which state the vehicle is from and roughly how old it is.
Every company registered in India has one: a Corporate Identity Number, 21 characters, assigned by the Registrar of Companies, unique and permanent. The CIN is structured, and each block carries a fact about the company. Read it properly and you know roughly what you’re dealing with before you open a single filing, which makes it the second thing to get hold of when you are checking whether a company is real before parting with money, right after the legal name.
The six blocks
Take a CIN in the shape U68200TS2023PTC999999 and split it. (It’s an
illustrative one, not a real company’s.)
| Block | Example | Meaning |
|---|---|---|
| 1 character | U |
Listing status |
| 5 digits | 68200 |
Industry classification |
| 2 letters | TS |
State of registration |
| 4 digits | 2023 |
Year of incorporation |
| 3 characters | PTC |
Company class and ownership |
| 6 digits | 999999 |
Registration number within that state |
Read left to right, that string says: an unlisted company, in real estate activities, registered in Telangana, incorporated in 2023, a private limited company that is a subsidiary of a public company.
All of that, before you’ve paid for anything.
The first character: listed or not
L means listed on a stock exchange. U means unlisted.
The great majority of Indian companies are unlisted, so U is what you’ll
usually see. But an L is worth noticing straight away. A listed company carries
much heavier disclosure obligations, which in practice means its information is
sitting in a dozen places besides the register.
The five digits: what it says it does
These are the industry classification digits. They record the activity the company declared when it registered.
That’s a genuinely useful cross-check, because companies drift. It’s common to find one whose stated business and actual business parted ways a decade ago. When the two disagree, that’s a question worth asking.
The two letters: state
The state or union territory of the Registrar where the company is registered.
TS Telangana, KA Karnataka, MH Maharashtra, DL Delhi, and so on.
One catch: this is the state of registration, not necessarily where the business actually operates. Plenty of companies register in one state and trade from another.
The four digits: year of incorporation
The most immediately useful block of the lot.
A company incorporated three months ago asking you for thirty days’ credit is a very different proposition from one incorporated in 1994. Age doesn’t equal quality. But it does bound how much history could possibly exist.
The three characters: class and ownership
This block is dense. The common values:
PTC: private limited, subsidiary of a public companyPLC: public limited companyFTC: subsidiary of a foreign companyGOI: government of India companySGC: state government companyNPL: not-for-profit under Section 8OPC: one person companyULL/ULT: unlimited liability
OPC is the one to watch for. A one person company has a single member, which
tells you something real about how concentrated the control is.
LLPs work differently
A limited liability partnership doesn’t have a CIN at all. It has an LLPIN, which
is shorter and shaped differently: typically three letters and four digits, like
ZZZ-0000.
So if the identifier in front of you isn’t 21 characters long, you’re probably looking at an LLP. Worth knowing, because the filings an LLP makes are not the same as a company’s, and the accounts sit in a different place.
Why the CIN beats the name
Here’s the thing people get wrong. Company names aren’t nearly as unique as you’d assume. Near-identical names exist across states. And names change, while identifiers don’t.
So if you’re recording a counterparty in a contract, a spreadsheet or a compliance file, record the CIN and not just the name. It’s the only identifier that will still point at the same entity in five years.
That’s also why every lookup should start there. You can search any Indian company or LLP on Entiva by name or by CIN, free, and see the identity, status and incorporation date straight away. Enough to confirm you’ve got the right entity before you spend anything on the filings behind it.
One last thing the CIN won’t tell you: whether the company still exists. That’s a separate field, and it’s the first one you should check.
