How to search by real business activity
The search covers every official code title from the NIC 2025 dataset plus related activity terms and legacy NIC 2008 signals already linked to current pages. Type a plain-language description of what your business actually does, such as wheat farming, software consulting or restaurant, and the results will surface matching Sub-classes ranked by relevance.
From there, open the code page to check the full hierarchy, source verification score and registration context before using it in a filing.
