Update Your Udyam Registration Without Re-registering

A Udyam update changes the details on a live Udyam registration, such as the address, activities, investment, turnover, employees or contact details. Your Udyam number stays the same and a revised certificate is issued. StampMitra is a filing assistance platform, not the government.

What a Udyam update is, and what it is not

Udyam registration is not renewed. Once you hold a Udyam number, you keep it. What changes over time are the details behind it: your address, the activities you carry on, your investment and turnover, the people you employ and how the portal can reach you. An update puts those details right on the same registration.

What you can update on the portal

Address: The unit address and the official address.

  • Address
  • Activities
  • Investment and turnover
  • Employees
  • Contact details
  • Bank and personal details

What stays fixed, and when you need a fresh registration

Tax number and identity number: The tax number on a Udyam registration and the owner's identity record are not edited on the update screen.

  • Tax number and identity number
  • Type of organisation
  • Enterprise name
  • A new entity or tax number

The refresh from your tax returns

The portal pulls investment and turnover through your tax number from your income-tax and GST data, and it can revise your class from that data. Keep your details current so what you see on the certificate matches your returns.

Class limits from 1 April 2025

Both investment and turnover are tested; exceeding either moves you up. Exports are not counted in turnover.

  • Micro: Up to ₹2.5 crore
  • Small: Up to ₹25 crore
  • Medium: Up to ₹125 crore

Common reasons an update stalls

The name does not match your tax and GST records.

  • The name does not match your tax and GST records.
  • Returns for the last financial year are not filed, so the portal shows older figures.
  • The registered mobile or email is lost, so the verification code cannot reach you.
  • The business has changed form but an update is attempted instead of a fresh registration.
  • Investment includes land and building, which should be left out.
  • Turnover includes exports, which are not counted for class.

Frequently asked questions

Does my Udyam number change after an update?

No. Sources say the number and the registration date stay the same and a revised certificate is issued. We confirm this on the portal when we file.

Is there a government fee for an update?

No. The Udyam portal charges nothing for registration, update or the certificate. Our fee is separate.

Do I have to update every year?

We do not state a yearly duty or date, because none is confirmed on the sources we could read. The portal refreshes your class from your tax data, so keep your returns filed and your details current.

Can I change the name of my enterprise?

The portal reads the name from your tax records and it may not allow a change. We check first. Update your tax, GST and registrar records before the Udyam name.

My business became a company. Can I update?

No. A new entity with its own tax number needs a fresh Udyam registration. The old registration is cancelled separately.

I only have the old UAM or EM-II. Can I update it?

No. Old memorandums are no longer valid, so you need a new Udyam registration.

I lost my certificate. Can you still update?

Yes, if the registration is live. We help recover the number on the portal and then update.

What if I cannot receive the verification code?

The update cannot start without it. Our team will advise a way to recover access to the registered mobile or email.

What happens if my class changes?

Moving up keeps the non-tax benefits of your earlier class for three years. A unit that becomes Medium loses delayed-payment protection at once.

Do you need my identity or bank number on this form?

No. We take identity and bank details securely after payment, and you enter the portal's verification code yourself.
