What is Companies House Number?
A company registration number is used to identify a company to verify that they are registered with Companies House. The number consists of a unique combination of numbers, and letters in some cases. It is specific to every company that is registered in the UK.
Company registration numbers apply to businesses registered at Companies House. Such as limited companies and limited liability partnerships. Sole traders do not have company registration numbers as they are not incorporated in this way.

What is the format of a Company Registration Number?
However, Companies House uses a special reference to distinguish between English and Scottish companies by allocating different prefix to the digits. For example, for the companies which are registered in Scotland. It will have prefix SC with the digits while for the companies which are registered in England and Wales will have eight digits. Companies registered in Wales don’t have any special reference number in their registration number to distinguish them from their English counterparts. However, they have an option to replace the word Limited or Ltd with either cyfngedig or cyf.
CRNs are always 8 characters long. These can be either 8 digits or 2 letters followed by 6 digits.
- English and Welsh companies have 8-digit CRNs beginning with 0 or 1.
- Scottish companies have CRNs with the letters ‘SC’ followed by 6 digits.
- Limited liability partnerships (LLPs) have the letters ‘OC’ followed by 6 digits.
- Scottish LLPs have the letters ‘SO’ followed by 6 digits.
- Northern Irish companies have the letters ‘NI’ followed by 6 digits.
- Northern Irish LLPs have the letters ‘NC’ followed by 6 digits.

Is a company registration number the same as a company tax number?
This is a common misconception, but a company registration number is not the same as a company tax number.
CRNs are issued by Companies House as unique identifiers for individual companies on the public register, whereas company tax numbers are unique 10-digit codes that HMRC assigns to companies to track their tax records.
Officially, a company tax number is referred to as a company’s Unique Taxpayer Reference, or ‘UTR’. Sometimes, it will simply be called a ‘tax number’ or ‘tax reference’.
- Is my company number the same as my tax number?
- Do UK companies have a TIN number?
You don’t have to apply for one – HMRC is notified by Companies House when new companies are formed. So, your company’s UTR will be automatically generated and sent to your registered office a few weeks after incorporation.
Likewise, do not confuse your company registration number with your VAT number, employer PAYE reference number, Government Gateway User ID, company authentication code, or any other number or reference that your company may be provided with.
