  • Udyam and MSME code research
  • Company or LLP registration preparation
  • Business activity shortlisting before filing
  • Internal classification and vendor profiling
How To Choose

How to Narrow Down From Section O

Choose Section O only if the business belongs to administrative and support service activities; then move down through Divisions rather than stopping at the sector label.

Common Questions About NIC O

Which businesses fall under NIC O?

Start here when the business belongs to administrative and support service activities and then compare child entries such as undefined undefined, undefined undefined, undefined undefined, undefined undefined and 2 more.

Is NIC O a final filing code?

No. This is a hierarchy page. Continue to the six-digit Sub-class before using a code in registration or compliance records.

How do I verify that NIC O is correct before filing?

Check the parent hierarchy, compare nearby sibling codes in the same parent category, and confirm that the official title matches the main revenue activity. For regulated or filing-critical decisions, verify the source row in the MoSPI dataset.

What happens if I use the wrong NIC code in Udyam or MCA registration?

A wrong code can cause mismatched business descriptions, follow-up questions or later compliance cleanup. It is better to compare nearby codes before filing than to correct a weak classification later.

Is there a legacy NIC 2008 equivalent for NIC O?

Use the legacy converter only as a migration aid. Old NIC 2008 matches can suggest where to look, but NIC 2025 should remain the primary reference for new code selection.
