Udyam Registration Corrections & Updates in 2026 – Fix Mobile, Email, Address, Turnover & NIC Code Step-by-Step are not as scary as people think – but only if you know exactly where to click, what you’re allowed to change, and what happens to your MSME status after the update.
Every week, thousands of MSMEs realise that something is wrong in their Udyam certificate – wrong mobile, email not accessible anymore, business shifted to a new address, turnover crossed a limit, or the NIC code no longer matches what they really do. The good news is: the official Udyam portal lets you update and even cancel your registration online, without needing any “agent” in between.
This guide walks you through each major type of correction in 2026 – mobile, email, address, turnover and NIC code – in clean, real-world language.

What This Guide Will Help You Fix
On the Udyam portal, you can normally update:
Mobile number
Email ID
Business address & PIN code
Turnover & investment values (which decide whether you’re Micro / Small / Medium)
NIC code(s) and business activities
Some other details like bank account, minor spelling issues, and in certain cases, closure/cancellation of the registration.
We’ll go step-by-step assuming:
You already have a valid Udyam Registration Number (UDYAM-XX-00-0000000).
You can access at least one of the contact details used at the time of registration (mobile or email).
If you can’t access both (SIM lost, email gone, etc.):

When You MUST Update Your Udyam Registration
It’s worth taking the effort to correct your certificate when any of these happens:
Mobile or email changes
You no longer use the registered mobile or email.
OTPs for any future update / verification will go to those old contacts.
You shift your business location
New shop/office/factory address
New city, district or state
Change in PIN code
Turnover / investment has changed significantly
You have grown and crossed from Micro → Small or Small → Medium
Or the opposite (downscaling) – reverse graduation.
Updated classification rules rely on both investment and turnover, and reclassification applies from a defined financial year.
Your main line of business has changed
You changed from trading to manufacturing, or from one NIC code to another.
Legal changes
Conversion from proprietorship to partnership / LLP / company (in some cases, you may need a fresh registration linked to a new PAN instead of just updating – more on this later).
Ownership transfer / merger.
You closed the business
You do not want to keep enjoying MSME benefits and want the record properly cancelled / deregistered.
How to Log In and Open Your Udyam for Editing
The basic flow to modify Udyam details is broadly the same across trusted explainers from lenders and advisors:
Go to the official Udyam portal
Open your browser and type the official address (or Google “Udyam Registration MSME portal” and choose the
.gov.inresult).
Click on “Update Details” / “Update Udyam Registration”
On the menu, look for Update Details → Update/Cancel Udyam Registration.
Enter your Udyam Registration Number
Example format:
UDYAM-JH-12-0001234.
Choose how you want to verify – mobile or email
Select OTP on mobile or OTP on email.
Use the same mobile/email that is printed on your current Udyam certificate.
Enter the OTP and log in as “Udyami”
Once OTP is validated, you are taken to the Udyami login / update form for your enterprise.
Edit the required fields
Make your changes (mobile, email, address, turnover, NIC, etc.).
Double-check before submitting.
Submit & confirm
Click Update / Submit.
In some cases, another OTP confirmation may be required.
Download / print the updated certificate
After approval, you can go to Print Udyam Certificate, enter mobile and OTP again, and download the revised certificate for your records.
How to Change Mobile Number in Udyam Registration
Changing mobile is both important and sometimes tricky, because OTPs go to the existing registered mobile.
If you still have access to the old SIM
Log in as described in the previous section using OTP on old mobile.
In the form, go to the contact details section.
Replace the old mobile number with the new one.
Save & submit.
After approval, future OTPs will go to the new mobile.
If you lost the old mobile / number is dead
Here it gets messy:
The portal will still send OTP to the old number.
If the SIM is permanently lost / inactive, you cannot complete OTP on your own.
In practice, you have three options:
Try email OTP route (if your email ID is still accessible and allowed for verification).
Contact the official Udyam/CHAMPIONS/MSME helpline and raise a grievance explaining that both mobile and number are inaccessible – they may ask for additional documents.
Work with a professional (like Eudyamaadhar) who can help prepare the right representation and documentation for correction.
If you have lost access to both mobile & email, don’t keep pressing random options on third-party sites.
Get human help once, fix it properly and keep the new details safe.
How to Change Email ID in Udyam Registration
Email is typically easier than mobile, provided you still have either:
The old email, or
The registered mobile.
Steps (similar to mobile change):
Log in via OTP on mobile or email.
In the contact details section, update the email ID.
Double-check spelling (a single wrong letter can lock you out again).
Submit the update.
After approval, future communication and OTPs (if email route is used) will come to the new email.
How to Correct Address, PIN Code & State
Address is essential for:
Bank loans – bank will cross-check address on Udyam with KYC and collateral.
Tenders, licences and inspections – government bodies may rely on Udyam data.
State-level benefits – your state determines which policies and subsidies you can access.
Steps:
Log in to the Udyam portal.
Go to the section showing business address / plant address.
Update:
Building / street,
Locality,
Village/town/city,
District,
State,
PIN code.
If you have multiple units, ensure each unit’s address is updated consistently in your other registrations (GST, pollution board, factory licence, etc.).
Submit the update.
Important tips
If you shift to another state, check if you also need to update GST registration state, local permits, and state-specific MSME schemes – some benefits are state-bound.
Always keep proof (rent agreement, property papers, electricity bill) ready – banks or authorities may ask later.
How to Update Turnover & Investment Details (Reclassification Rules)
Your MSME category (Micro / Small / Medium) is determined using a composite criteria of investment in plant & machinery/equipment and turnover, as per revised norms periodically updated by the government and RBI.
Why updating turnover/investment matters
Banks rely on your MSME category for deciding which schemes and priority-sector norms apply to you.
Some schemes are meant only for Micro or Micro & Small enterprises.
If your turnover has grown (or fallen) significantly, you may move to a new category – this is called graduation or reverse graduation.
Official FAQs clarify that when a reclassification is due because of actual changes in turnover/investment, the new status becomes effective from 1st April of the following financial year.
How to update these numbers
Log in to the portal.
Go to the investment & turnover section.
Update:
Investment in plant & machinery/equipment (approximate but reasonable and verifiable).
Turnover figures (as per your latest financial year data – GST/ITR).
Ensure that figures broadly match what is visible in income tax & GST systems – the government cross-checks with IT/GSTN feeds to validate classification.
Submit and note any change in your MSME category displayed.
Don’t game the system
Avoid the temptation to knowingly understate turnover just to stay in Micro:
Banks, tax departments and GST systems see your real figures anyway.
Mismatch can raise more questions during loan appraisal than it “saves” you in benefits.
How to Change NIC Code & Main Business Activity
The NIC (National Industrial Classification) code tells the government what you actually do – manufacturing, trading, specific services, etc.
Over time, many MSMEs shift from one line to another:
A trader starts small manufacturing.
A manufacturer adds a big service component.
A freelancer becomes a consulting company.
You can modify/add NIC codes via the update function on the Udyam portal; advisory pages and NIC-code guides confirm that you can log in, edit activities and change/add relevant NIC codes.
Steps:
Log in to your Udyam profile.
Go to the Business Activity / NIC code section.
You may see:
Manufacturing activities (with NIC codes)
Service/trading activities (with NIC codes)
Add, edit or remove codes so that the major revenue-generating activities are correctly reflected.
Make sure the NIC code also aligns with:
Your GST registrations,
Your bank projection / project report,
Any licences (shop & establishment, FSSAI, clinic licence, etc.).
Practical tip
If you are applying for a scheme or loan targeted at a particular sector (e.g., manufacturing, women-led services, export), a correct NIC code helps avoid confusion at the scrutiny stage.
Other Common Changes: Bank Details, Name, Constitution & Cancellation
Besides the big five (mobile, email, address, turnover, NIC), you may need to handle:
1. Bank account details
Some banks like to see that the account used for business matches the account on Udyam and other registrations.
If you open a new current account, it’s a good practice to update this too.
2. Spelling corrections in name
Minor spelling mistakes in promoter name or enterprise name can create mismatches when linking with PAN, GST and bank KYC.
If your PAN-based name or GST name is slightly different, try to harmonise them.
Small spelling fixes can often be made using the same update flow.
3. Change in constitution / legal form
This is more sensitive:
If you convert from proprietorship to company/LLP, technically the PAN changes.
Many advisors recommend fresh Udyam registration for the new entity instead of just editing the old one, since the legal person has changed (this is also the approach seen in official clarifications & FAQs).
For complex changes like this, it’s better to talk to a CA/consultant once.
4. Cancelling / closing Udyam
If the business is closed, merged into another, or you no longer want MSME status, the portal also supports Update/Cancel Udyam Registration under the same menu.
Deregistration reasons include: ownership changes, duplicates, or business closure, as seen in government replies about MSME deregistrations.
Cancel if you’re not operating at all; don’t cancel just because business is “slow”.
What Happens After You Submit Updates
After you submit corrections:
The updated data is recorded instantly on the portal on your side.
In the background, systems may cross-check with:
Aadhaar / PAN,
GST and IT databases (for investment/turnover),
Other internal checks.
If everything is fine, your status and certificate show the new details.
For reclassification (Micro ↔ Small ↔ Medium), the benefit of the new category generally applies from the start of the next financial year, as per clarifications on reverse graduation and classification.
Always:
Save a PDF copy of the new certificate.
Keep a screenshot or printout of the update confirmation for your files.
How Wrong Details Can Hurt Your MSME Loan & Scheme Eligibility
Incorrect Udyam details are not just a “small clerical issue”. They can:
Slow down or block bank loans, especially MSME/priority-sector loans.
Create mismatch when applying for PMEGP, CGTMSE, Stand-Up India, state subsidies, etc., which rely on accurate MSME categorisation.
Complicate tenders and GeM registration, where address & category must match.
Reduce credibility when lenders pull data from multiple systems (PAN, GST, Udyam, credit bureaus).
If you’re planning to apply for any big loan or subsidy in 2026, fixing Udyam before you approach banks is a smart step.
FAQs on Udyam Corrections & Updates in 2026
1. Is there any government fee for updating Udyam registration?
No, on the official Udyam portal, updating your details (mobile, email, address, turnover, NIC etc.) does not carry a government fee. Some private service providers charge a service fee for assisting you, but that is separate from the government system.
2. How often can I update my Udyam details?
There’s no strict “only once per year” rule mentioned publicly. In practice, you can update whenever there is a genuine change in your business information – especially for contact details, address and business activities. For turnover/investment, classification benefits apply based on financial year data.
3. Do I need CA-certified figures to update turnover and investment?
The portal generally asks for figures in line with your books / ITR / GST data; it doesn’t ask for documents at upload stage. But banks and agencies may later expect your CA to support those numbers during loan or scheme processing. It’s wise to keep your CA involved when changing financial data.
4. Can I change my PAN in Udyam?
If the legal entity changes, the PAN typically changes too (e.g., moving from proprietorship to company). In such cases, guidance from MSME-related FAQs and professionals is that you should generally apply for a fresh Udyam registration for the new entity rather than simply editing PAN.
5. Will updating Udyam affect my existing MSME loans?
Normally, simple corrections (mobile, email, address) do not disturb existing loans, but it’s good to inform your bank of major changes, especially address and classification. If your category changes (Micro → Small, etc.), it could affect future benefits or limits, not usually the past sanctions.
6. How long does it take for changes to reflect?
Most changes reflect immediately on your profile once you submit and OTP-verify. For classification-related implications (like category change), the impact on benefits is tied to financial year rules and underlying data, not just the moment you press “Submit”.
7. Can I update Udyam using a mobile phone?
Yes, the official portal is mobile-friendly and many small businesses access it through smartphones. Just ensure:
Stable internet,
You can receive OTP on the same phone or check email on another device.
