Udyam registration is the official way for micro, small and medium enterprises (MSMEs) in India to get recognised by the government. It is completely free, paperless and based on Aadhaar, PAN and GST data. Once you complete Udyam registration, you receive a permanent Udyam Registration Number and an e-certificate that unlocks a long list of benefits: easier bank loans, collateral-free credit, protection against delayed payments, subsidies, tender advantages and more.
Whether you run a tailoring unit, a bakery, a small manufacturing workshop, a digital agency or a trading shop, this complete guide explains Udyam registration step by step. You will learn eligibility, the new MSME classification limits, documents required, the online process, how to download the certificate, how to update details, and how to avoid fake websites that charge money for a free service.

What Is Udyam Registration?
Udyam registration replaced the old Udyog Aadhaar Memorandum (UAM) and EM-II systems from July 1, 2020. It is managed by the Ministry of Micro, Small and Medium Enterprises through the official portal udyamregistration.gov.in. The system automatically pulls investment and turnover information from income tax and GST databases, which reduces paperwork and makes the certificate more reliable.
Key highlights:
- No fee for registration
- No documents need to be uploaded
- Self-declaration based process
- Permanent number with no renewal required
- e-certificate with a dynamic QR code
- One registration per enterprise (multiple units and activities can be added)
MSME Classification Limits (Revised)
The government revised the MSME classification limits with effect from April 1, 2025, raising both investment and turnover thresholds. The current criteria are:
| Category | Investment in plant, machinery or equipment | Annual turnover |
|---|---|---|
| Micro | Up to ₹2.5 crore | Up to ₹10 crore |
| Small | Up to ₹25 crore | Up to ₹100 crore |
| Medium | Up to ₹125 crore | Up to ₹500 crore |
An enterprise must satisfy both conditions (investment and turnover) to fall into a category. If it crosses either limit, it moves to the next category. The same limits apply to both manufacturing and service enterprises.
Who Can Apply for Udyam Registration?
Any person who intends to establish or already runs a micro, small or medium enterprise can apply. This includes:
- Proprietorship firms
- Partnership firms and LLPs
- Private and public limited companies
- Hindu Undivided Families (HUF)
- Co-operative societies and trusts
- Self-help groups and other legal entities
Both manufacturing and service businesses are eligible. Since 2021, retail and wholesale traders can also register, but they get priority sector lending benefits only (not all other MSME benefits).
Documents and Details Required
You don’t need to upload any document, but keep these details ready:
- Aadhaar number of the proprietor, managing partner, Karta or authorised signatory
- Mobile number linked with Aadhaar for OTP
- PAN of the enterprise (mandatory for companies, LLPs, partnerships; proprietors use personal PAN)
- GSTIN, if GST registration is mandatory for your business
- Bank account number and IFSC
- Business address and plant/unit locations
- Date of commencement of business
- NIC code describing your main business activity
- Number of employees (male, female, others)
- Investment and turnover figures (auto-filled from ITR/GST where available)

Udyam Assist Platform for Informal Micro Enterprises
Very small businesses such as street vendors, home-based workers and artisans who do not have PAN or GST can register through the Udyam Assist Platform (UAP), run with the support of SIDBI. Registration is done through designated agencies such as banks, NBFCs and CSCs using Aadhaar. These enterprises are treated as micro enterprises for priority sector lending.
Benefits of Udyam Registration
- Collateral-free loans: Under the Credit Guarantee Fund Trust for Micro and Small Enterprises (CGTMSE), banks can lend without collateral.
- Priority sector lending: Banks give priority to registered MSMEs, often at better interest rates.
- Protection against delayed payments: Buyers must pay micro and small suppliers within 45 days (where agreed) under the MSMED Act. You can file complaints on the MSME Samadhaan portal.
- Income tax rule 43B(h): Large buyers can claim deductions for payments to registered micro and small enterprises only when paid on time, which encourages faster payments.
- Government tenders: Exemption from earnest money deposit (EMD) and preference in public procurement, including on GeM.
- Subsidies: Patent registration fee concession, ISO certification reimbursement and barcode registration subsidies.
- Electricity and tax concessions offered by various state governments.
- Eligibility for schemes like PMEGP, Mudra and state industrial incentives.
Our guides on PMEGP loan online apply and Mudra loan online explain how Udyam-registered businesses can access funding.
How to Update Udyam Registration Details
If your address, bank, activity or employee numbers change, update the record online:
- Visit the portal and click Update Details > Update/Cancel Udyam Registration.
- Enter the Udyam number and mobile/email, verify OTP.
- Edit the required fields and submit.
Investment and turnover are updated automatically from ITR and GST every year, and the classification may change accordingly.
Udyam Registration for Existing Udyog Aadhaar Holders
If you registered under the old Udyog Aadhaar (UAM) system, it is no longer valid. You must migrate by clicking “For those having registration as UAM” on the portal and completing Udyam registration with OTP. Your old details are used as reference, but the new certificate is what banks and departments accept.
Beware of Fake Udyam Websites
Many private websites look like the official portal and charge ₹1,000 to ₹5,000 for “MSME registration”. The government service is free. Always check that the website address is udyamregistration.gov.in. Do not share your Aadhaar OTP with unknown agents. If you need help, visit your District Industries Centre (DIC) or a CSC.
Common Mistakes to Avoid
- Entering a name different from Aadhaar spelling
- Choosing the wrong NIC code for the main activity
- Registering the same enterprise twice with different PANs
- Using a personal mobile that is not linked to Aadhaar
- Not updating GSTIN after obtaining GST registration
How to Choose the Right NIC Code
The National Industrial Classification (NIC) code describes what your business does. The portal shows a search box where you can type keywords such as “bakery”, “tailoring”, “software”, “beauty parlour” or “printing”. Select the closest description for your main activity first, and then add secondary activities if needed. Choosing the right code matters because some schemes and tenders are open only to specific sectors. For example, a manufacturer of wooden furniture should pick a manufacturing code, while a furniture repair service should choose a service code. If you are unsure, the District Industries Centre can guide you.
Manufacturing vs Services vs Trading
Manufacturing enterprises convert raw materials into new products, such as food processing, garments, metal fabrication or pottery. Service enterprises provide services like repairs, IT, consulting, logistics, tourism, beauty or education. Trading enterprises buy and sell goods without changing them. While all three can apply, traders mainly get priority sector lending benefits. If you both manufacture and sell your own products, choose manufacturing as the major activity, because that unlocks the widest range of benefits.
How to Calculate Investment and Turnover
Investment means the written-down value of plant, machinery or equipment as per the previous year’s income tax return. Land and buildings, furniture and fittings are not counted. For new enterprises without an ITR, the self-declared purchase value of machinery is used. Turnover excludes export turnover, which means exporters can grow their foreign sales without losing MSME status. Turnover is linked with GST returns for businesses registered under GST, so make sure your returns are filed correctly.
Udyam Registration Number Format Explained
A typical Udyam number looks like UDYAM-KL-07-0012345. Here, “KL” is the state code (Kerala), “07” is the district code, and the last seven digits are the unique serial number of your enterprise. Mention this number on invoices, quotations and websites to build trust with customers and buyers.
Using Udyam Certificate to Get Loans
Banks increasingly ask for a Udyam certificate when you apply for business loans, overdrafts or working capital limits. With the certificate, you can apply under schemes such as CGTMSE for collateral-free loans, the PSB Loans in 59 Minutes portal, Mudra loans for micro units, and state-level interest subvention schemes. Keep your bank statements, ITR, GST returns and a simple project report ready along with the certificate to speed up approval.
MSME Samadhaan: Recover Delayed Payments
One of the most valuable benefits for small suppliers is protection against late payments. If a buyer does not pay within the agreed period (maximum 45 days), a micro or small enterprise can file a complaint online on the MSME Samadhaan portal using its Udyam number. The case is referred to the Micro and Small Enterprises Facilitation Council (MSEFC) of the state, which can direct the buyer to pay the amount with compound interest at three times the bank rate notified by RBI. This gives small businesses real bargaining power with large customers.
Registering on GeM and TReDS
During registration, the portal asks whether you want to be onboarded on the Government e-Marketplace (GeM) and the Trade Receivables Discounting System (TReDS). GeM lets you sell products and services directly to government departments. TReDS lets you convert unpaid invoices from large buyers into cash quickly through financiers. Both platforms can help micro businesses grow beyond local markets.
Udyam Registration for Women Entrepreneurs
Women-owned enterprises receive special support under many central and state schemes, including higher subsidy rates under PMEGP, interest concessions from some banks and reserved procurement targets. Mark the gender of the owner correctly during registration so these benefits can be applied. Women running home-based businesses such as catering, tailoring, handicrafts or online stores should complete Udyam registration to access these opportunities.
How to Cancel Udyam Registration
If you close your business permanently, you can cancel the registration through the “Update/Cancel Udyam Registration” option. Select the cancellation option, give the reason, verify with OTP and submit. Cancelled registrations cannot be restored, so be sure before you proceed.
Udyam Registration Checklist
- Aadhaar and linked mobile ready for OTP
- Enterprise PAN and GSTIN (if applicable)
- Bank account and IFSC
- Correct business name and address
- Date of commencement
- NIC codes selected
- Employee count
- Investment and turnover details
Real-Life Example: A Home Bakery in Kerala
Anitha runs a small home bakery in Thrissur, selling cakes and snacks through WhatsApp and local shops. She completed Udyam registration in twenty minutes using her Aadhaar and personal PAN, selecting a food-manufacturing NIC code. With the certificate, she applied for a small business loan to buy an industrial oven, got her FSSAI registration processed faster, and started supplying to a nearby café chain that preferred registered vendors. When one buyer delayed payment for three months, the Udyam number gave her the confidence to raise the issue formally, and the payment was cleared soon after.
Udyam Registration vs GST Registration
These two registrations serve different purposes. GST registration is a tax requirement based on turnover and type of supply, while Udyam registration is a recognition of your enterprise as an MSME. You can have Udyam without GST if your business is below the GST threshold, and you can have GST without Udyam, though you would miss out on MSME benefits. Most growing businesses benefit from having both, and the Udyam portal links the two automatically using your PAN.
After Udyam Registration: Next Steps
- Download and print the certificate; keep a digital copy in DigiLocker or cloud storage.
- Add the Udyam number to your invoices and letterhead.
- Open a current account in the business name if you do not have one.
- Explore state industrial department schemes for MSMEs.
- Register on GeM if you want to sell to government buyers.
- File ITR and GST returns on time so your classification stays accurate.
