Your Company Registration Number (CRN) is unique to your limited company or LLP. You can find it on your certificate of incorporation and any official documentation received from Companies House. Your CRN is also displayed on the public register of companies, which can be accessed online via Companies House Service.
A Company Registration Number is a combination of 8 alpha-numeric digits. It is used to identify your company and verify its incorporation with Companies House, and is automatically issued upon company formation. You cannot choose or change your CRN; however, there are a few variations in CRNs:
- Companies in England and Wales
CRN will be made up of 8 numeric digits.
- Companies in Scotland
CRN will begin with the letters ‘SC’, followed by 6 numbers
- Companies in Northern Ireland
CRN will begin with the letters ‘NI’, followed by 6 numbers
- LLPs in England and Wales
CRN will begin with the letters ‘OC’, followed by 6 numbers
- LLPs in Scotland
CRN will begin with the letters ‘SO’, followed by 6 numbers
- LLPs in Northern Ireland
CRN will being with the letters ‘NC’, followed by 6 numbers
You should not confuse your Company Registration Number with your company’s Unique Taxpayer Reference (UTR). They are entirely separate and serve different purposes.
