Companies House Authentication Codes
This blog provides an overview of Companies House authentication codes. It is based on the Companies House web site https://www.gov.uk/guidance/company-authentication-codes-for-online-filing
What is an Authentication Code?
The Companies House code is a 6 character alphanumeric code issued by Companies House to each company. The code is used to authorise information filed online at Companies House.
Obtaining an Authentication Code
A code can be requested from Companies House. Once a code is requested, it is sent to the Company’s Registered Office. It can take up to 5 days to arrive. For security reasons, the code cannot be sent by either email or provided over the phone.
Using the Authentication Code
The same code can be used whether you are using the Companies House online filing service or third party software. In order to use Companies House online filing services, you have to register your email address and password. To file using third party software, you have to set up an online filing account. You also must obtain a presenter ID and authentication code.
Changing the Code
It is possible to change or cancel the code using the “Company Authentication” section of the Companies House Online Filing service. You should tell anyone who files on behalf of the company that the code has been changed.
Looking After the Companies House Authentication Codes
The Companies House code should be treated with the same level of care as a bank card PIN. Anyone who knows the code can amend your company’s details at Companies House. You should also only share the code with those that you trust to file information for your company at Companies House. If your code becomes known to someone that you do not trust then change it.
Changing the Code
You should change the code if it is known by someone who you do not want to file information for your company. This may be either a staff member who leaves or your previous accountant. If you change the code, mix letters and numbers so that the code is not easy to guess.
Companies House will never ask for an authentication code over the phone. If you are contacted by someone claiming to be from Companies House who requests your code, you should not give it to them and report it to Companies House immediately.
