What Is LLP Identification Number (LLPIN)? Format & Search

What proves that your business really exists? It is neither your website nor the pitch deck you made for fundraising. Even the logo, name, or the partners behind it justify legal existence. For a Limited Liability Partnership, its identity begins with one powerful code: the LLP identification number (LLPIN). If you miss it, misplace it, or misunderstand it, even the successful businesses can come to a sudden halt.

This number is the legal heartbeat of your LLP. Every filing, approval, and official record traces back to this single identifier. In this blog, we unpack everything you need to know about LLPIN. You will learn what LLPIN means, how its format works, and the fastest ways to find it when you need it most. 

What is an LLPIN Number and Why Does it Matter?

An LLP Identification Number, or LLPIN, is a 7-digit unique alphanumeric number assigned to every Limited Liability Partnership in India. The Registrar of Companies issues this number after the Ministry of Corporate Affairs (MCA) successfully approves LLP registration. From that point, the government legally recognizes the LLP.

LLPIN acts as the official fingerprint of an LLP. It allows authorities, banks, and stakeholders to identify a business without confusion. Even if two LLPs have similar names, their LLPINs will always be different.

Why is LLPIN Important?

LLPIN number plays a critical role in the day-to-day functioning of an LLP. It is required for:

• Filing annual returns and compliance forms on the MCA portal
• Submitting income tax returns and disclosures
• Opening and operating bank accounts
• Completing KYC and verification checks
• Mentioning the LLP in contracts and legal documents
• Submitting Form 11 (Annual Return) and Form 8 (Statement of Accounts and Solvency) for compliance

This number remains constant throughout the life of the LLP. It does not change with partner additions, name changes, or business modifications.

In simple terms, LLPIN keeps your LLP compliant, traceable, and legally valid. Without it, an LLP cannot operate smoothly within India’s regulatory system.

How to Get LLPIN?

The MCA automatically generates the identification number during registration. The issuing authority, ROC, approves the incorporation application, and the LLP receives this unique number.

The allotment process is simple:

• Application Submission: The proposed LLP submits Form FiLLiP (Form for Incorporation of LLP) on the MCA portal.
• Verification by ROC: The Registrar checks partner details, proposed name, and business activities.
• Approval and Number Generation: After approval, the system automatically generates the unique identification number.
• Issuance of Certificate: The Registrar prints the number on the Certificate of Incorporation (COI) as official proof of the LLP’s existence.

The process usually takes a few days, depending on document accuracy and ROC workload. RegisterKaro offers end-to-end support for LLP incorporation, helping you avoid errors, rejections, or delays during LLP registration.

How to Find Your LLPIN?

Knowing where the LLPIN number appears helps you maintain compliance, avoid delays, and quickly verify your entity with authorities, banks, and business partners.

• COI: Printed as proof of legal existence
• LLP MCA Master Data: Listed alongside your LLP’s name, registered address, partners, and status
• LLP Agreement: Included in most agreements to legally identify the partnership
• PAN and TAN Documents: Used by banks to link tax records to the LLP

Keeping your LLPIN accessible in official documents ensures smoother compliance and faster filings.

What is the LLP Identification Number Format?

An LLPIN uses an alphanumeric format with 7 characters in total. The standard pattern is ABC-1234. The LLPIN number format makes it easy to verify and ensure that no two LLPs share the same identification number. 

The structured LLPIN’s format works like this:

• First 3 characters (Alphabetic prefix)
  • Always letters
  • Assigned in a sequential series
  • Indicates the registration series, not the location or activity
• Last 4 characters (Numeric digits)
  • Always numbers
  • Generated in ascending order
  • Makes each LLPIN unique within the series

This structure ensures that no two LLPs ever share the same identification number.

An LLPIN number like ABC-1234 serves as a clear LLPIN number example.

Key Features of LLPIN Format

The LLPIN format has several key features that make it unique, consistent, and easy to use for all LLPs. These include:

• Always 7 characters long
• Uses a 3-letter + 4-digit pattern
• Generated automatically by the MCA system
• Remains unchanged throughout the LLP’s life

The MCA keeps the format consistent regardless of the state, industry, or size of the LLP.

How to Verify and Find Your LLPIN on the MCA Portal?

You can find your LLPIN easily using the Ministry of Corporate Affairs (MCA) portal. There are two main ways for LLP identification number search:

• Based on Existing LLP Name: Use this method if you know the registered name of your LLP. The portal will display the LLPIN along with the LLP’s master details.
• Based on LLPIN: Use this if you already have the LLPIN but want to verify or view additional details. This method quickly confirms the LLP’s current status and master data.

Follow these steps to easily find your LLPIN on the MCA portal:

1. Visit the official MCA portal.
2. Navigate to MCA Services, select LLP Services, and click on Find LLPIN.
3. Choose your search criteria: either the existing/old LLP name or LLPIN.
4. Enter the LLP name or partial name (if searching by name).
5. Complete the captcha and submit.
6. View the LLPIN and master details, including registered address, partners, and status (active or inactive).

This process ensures you can quickly retrieve and verify your LLPIN whenever needed for compliance, banking, or official purposes.

Tips for LLP Identification Number Verification:

• Always cross-check the LLPIN online from official MCA records before using it in forms or agreements.
• An incorrect LLPIN can lead to filing errors, compliance issues, or delays in approvals.
• Keep a record of the verified LLPIN for future reference.

LLPIN vs CIN vs Other Business Identification Numbers

The government assigns every business in India a unique identification number for legal, tax, and compliance purposes. While an LLP has its LLPIN, companies, directors, and tax filings use other numbers like CIN, DIN, etc. 

Here’s a quick comparison:

Identifier	Stands For	Applicable To	Format	Purpose
LLPIN	LLP Identification Number	Limited Liability Partnerships	3 letters + 4 digits (e.g., AAA-1234)	Legal identity, MCA filings, compliance, banking
CIN	Corporate Identification Number	Companies (Private & Public)	21 characters alphanumeric	Legal identity, MCA filings, regulatory compliance
DIN	Director Identification Number	Directors of Companies & Designated Partners of LLPs	8 digits	Identifies individual directors/partners
PAN	Permanent Account Number	Any entity or individual with tax obligations	10 characters alphanumeric	Income tax identification
GSTIN	GST Identification Number	Businesses registered under GST	15 characters alphanumeric	GST compliance and tax reporting

Knowing the distinction between these business identification numbers helps you use the right number in the right context.

Common Mistakes Related to LLPIN and How to Overcome Them

Even though the LLP identification number is simple and straightforward, LLPs often make avoidable mistakes that can cause delays in compliance, filings, or banking. Being aware of these errors and knowing how to fix them can save time and prevent unnecessary problems.

• Confusing LLPIN with CIN or DIN: Using CIN (Company Identification Number) or DIN (Director Identification Number) instead of LLPIN in filings. Always verify the number before submission; remember, LLPIN is specific to LLPs.
• Using an Incorrect LLPIN: Entering a wrong or mistyped LLPIN in forms or documents. Copy the LLPIN directly from the COI or MCA portal to avoid errors.
• Failing to Update Records: Relying on outdated documents that may list an LLP incorrectly or reference old data. Regularly check your LLP master data on the MCA portal to confirm the LLPIN and other details.
• Not Verifying LLPIN Before Filing: Submitting compliance forms without confirming the LLPIN can lead to rejections or delays. Always verify the LLPIN online through the MCA portal before using it in filings or agreements.

Avoiding these errors and fixing them saves time and prevents unnecessary problems.
