What is the Company Authentication Code?

The Companies House Web Filing authentication code is issued to all eligible companies incorporated in the UK. This 6 character alphanumeric code is used as a means to verify that someone is authorised to file documents on behalf of the company. 

The code is automatically issued at the time of incorporation. If a company was formed with Companies House directly the code will be posted the company’s registered office address.

Formation agents should also be able to provide the code as soon as a company is formed.

If you formed a company using Simple Formations you can find your code in the company documents accessible via your online portal.

What is it used for?

The authentication code provides access to the Companies House Web Filing service. This can be used to file various documents online. This enables a company to easily update the current appointments and file statutory documents.

What if the code is lost?

If you do not have access to the authentication code or have misplaced this, you can request a reminder of the code via the Companies House Web Filing site.  The code will then be sent to the registered office address within approximately 3-5 working days.

More information on using the Companies House Web Filing service can be found on our helpful guide.
