A Companies House personal code is the private code issued after an individual completes an identity-verification process. It is intended to link the verified individual to relevant company roles or filings. The code is personal to the individual, rather than to the company.

Where you may need it

Companies House may ask for an identity-verification personal code in specific journeys, such as taking up or confirming a director or PSC role. The exact use depends on the filing service and the current requirements, so follow the instructions displayed during the filing.

Keep the code secure

  • Store it in a reputable password manager or another secure record.
  • Do not publish it in company filings, documents, emails or shared finance folders.
  • Do not assume an accountant or co-director can use it without the appropriate process.
  • Check official guidance if you cannot find the code or believe it has been compromised.
A company number and a personal code are different

Your company number identifies the company on the public register. A personal code relates to an individual’s completed identity-verification process. Keep both records accurate, but treat the personal code as confidential.
