Short answer: on udyamregistration.gov.in, open Print / Verify → Forgot Udyam/UAM No. Choose “Udyam Registration”, choose whether to receive the OTP on mobile or email, and enter the mobile number or email address that was filled in your original application. Enter the OTP, and the portal shows every registration number linked to that mobile or email. The hard part is not the steps. It is that the portal only recognises the contact details typed into the application, and for many businesses that was an agent’s or a CA’s phone, not the owner’s. This guide covers that case too, along with what to do when neither the mobile nor the email works any more.
This is general information, not legal or tax advice. Use only the official portal, udyamregistration.gov.in, for anything involving your registration.
Your Udyam number is a 19-character code in the format UDYAM-XX-00-0000000: the word UDYAM, a two-letter state code, a two-digit district code and a seven-digit serial number. It never changes once issued, so it is probably already written down somewhere. Before you start chasing OTPs, spend five minutes on these:
If one of these turns it up, skip straight to downloading the certificate (further below). If not, use the portal.
This is the official recovery tool. It is free and takes a couple of minutes.
Note the number down somewhere you will find it again: in your accounting software, on your invoice template, and in a note on your phone.
The tool does not look up your Aadhaar-linked mobile or the number on your PAN. It looks up only the mobile and email that were typed into the Udyam application. When the OTP never arrives or nothing is found, it is usually because the application was filled with different contact details than the ones you are trying. The common culprits:
Try the other channel (email if mobile failed, or the other way round) before anything else. One OTP channel working is enough.
Because the recovery tool shows every registration linked to a mobile or email, a consultant who used their own phone for many clients will see a list of numbers when they run it. So the quickest fix is a short message: “Please share my Udyam registration number, and the mobile and email you used in my Udyam application.” Ask for both details, not just the number, because you will need an OTP on one of them every time you download the certificate or update anything.
Once you have the number, log in through Update Details (the login offers an OTP on either the application mobile or the application email) and change the contact details to your own. Your registration should not depend on someone else’s phone.
You are fine. Run the recovery tool with the channel that still works. Then use Update Details: the Udyami login asks for the Udyam number and the application mobile number, and lets you choose to receive the OTP on the application email instead. After logging in, replace the dead mobile or email with a current one, so the next recovery is easy.
This is the one situation the portal cannot solve by itself, because every self-service route ends in an OTP to one of those two. You have two official routes:
Expect this route to take longer than an OTP. If you need the number urgently for a loan or tender, tell the bank or buyer it is being retrieved, and check first whether they already have it in their records from an earlier transaction.
Not on the public portal. The official recovery tool works only with the mobile or email from the application, and the “Verify Udyam Registration Number” page works the other way round: you enter a number and it confirms the details. There is no public search by PAN, Aadhaar or business name. Websites that promise to “find your Udyam number by PAN” are either asking you to pay a private agent or using a paid business-verification service meant for lenders. Neither is necessary when a free route exists.
It is tempting to file a fresh application and move on. Don’t. The government notification that created Udyam (S.O. 2119(E) dated 26 June 2020) says no enterprise shall file more than one Udyam Registration, and that anyone who intentionally misrepresents or suppresses self-declared facts is liable to a penalty under Section 27 of the MSMED Act. Registration is linked to PAN and Aadhaar, so a duplicate is likely to be caught in any case. Two registrations can also cause trouble later, for example when a buyer, a bank or the ODR portal for MSME delayed payment complaints checks your number. Recover the original instead.
If you registered before 1 July 2020, you may have a Udyog Aadhaar Memorandum number rather than a Udyam number. The same Forgot Udyam/UAM No. page handles it: choose “Udyog Aadhaar Memorandum” in the first step. But UAM registrations are no longer valid for MSME benefits and had to be moved to Udyam. If you only ever had a UAM, recovering it is the first step, not the last: use it to register on Udyam (the portal has a separate option for UAM holders), and you will get a proper Udyam number.
Finding the number does not give you the certificate. That is a separate step:
Before you file it away, read the certificate. Check that the enterprise name, the type of organisation, the address and the NIC codes (your business activities) are right. Mistakes are common when an agent filled the form, and it is easier to fix them now through Update Details than when a bank or buyer points them out.
Does it cost anything to recover my Udyam number?
No. The recovery tool, the certificate download and Udyam registration itself are free on the government portal. You do not need to pay any website or agent for them.
I entered my Aadhaar-linked mobile and no OTP came. Why?
The tool only recognises the mobile or email typed into the Udyam application, which may be different from the one linked to your Aadhaar. Try the email option, and ask whoever filled your form which contact details they used.
The tool showed more than one number. Which is mine?
The tool lists every registration linked to that mobile or email, so a family member’s or consultant’s other registrations may appear. Verify each one on the “Verify Udyam Registration Number” page and match the enterprise name.
Does my Udyam number expire?
No. The notification calls it a permanent identity number, and there is no renewal. What you do have to do is keep the details updated, including GST and income tax return information; the notification says failing to update can lead to suspension of your status.
Can I recover the number of a partnership firm or company the same way?
Yes. The process is the same for every type of enterprise. It depends only on the mobile or email filled in the application, which for a firm or company is often the authorised signatory’s or the accountant’s.
Do I need a Udyam number for GST registration?
No. They are separate registrations, and CBIC has said an Udyam certificate is not required for GST registration. See our guide on the documents you do need for GST registration premises.
Your Udyam number matters most when money is involved: a bank loan such as a Mudra loan, a buyer’s vendor registration, or a complaint about a delayed payment. Keep it where you can find it.
