Common Questions About NIC 711005

Does NIC 711005 cover regulated professional or financial work?

Use the code that matches the service actually provided. Financial intermediation, insurance, real estate, legal, accounting, consulting, engineering, advertising and R&D are separated into different professional service families.

Can an advisory firm use NIC 711005 if it serves another industry?

Usually the firm's own service determines the NIC code, not the client's industry. For example, a consultant serving manufacturers is still a consulting or professional service business if advice is the revenue activity.

How do I verify that NIC 711005 is correct before filing?

Check the parent hierarchy, compare 711001 Building design and drafting, 711002 Town and city planning and landscape architecture, 711003 Engineering design and consulting, 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 711005?

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.

NIC 2026 guidance

Before you select NIC 711005

NIC 711005 should be selected only when the official title matches the main revenue-generating activity. If the business also trades, transports, processes, installs or supports the same product or service, compare nearby NIC pages before filing. This reduces the risk of choosing a code that describes the product being handled rather than the activity your enterprise actually performs.
