What do the Company Number Prefixes mean?
Company Number Prefixes are used for non-standard companies registered in the UK on the Companies House register. These prefixes help differentiate various types of companies, including overseas companies and those registered outside of England and Wales, such as Scotland and Northern Ireland. Historically, Scotland and Northern Ireland maintained their own company registers, which is reflected in the unique prefixes assigned to businesses from these regions.
The prefix typically consists of two characters placed at the beginning of the company number. For instance, NI is used for companies registered in Northern Ireland, and FC is assigned to overseas companies.
Below you'll find a list of the active prefixes. Please note these do change from time to time so the list should not be viewed as exhaustive.
