Depending on how you originally formed your company, for example directly with Companies House, or through using a using a company formation agent, there are a number of ways to retrieve your code.

Your company was formed directly with Companies House

If you formed your company by directly registering with Companies House through their postal service or online via web incorporation, you can simply request a replacement authentication code by doing the following:

You can sign up for one online. If you already have a WebFiling account, you can sign in and then follow these steps:

  1. Choose ‘request an authentication code’.
  2. Enter where the company was registered and fill in your company number, and click ‘continue’.
  3. Your company name, number and registered office address will then be displayed. From here simply select ‘request code’.
  4. Your new authentication code will be sent to your registered office by post, usually you will receive this within 3 to 5 working days.

Your company was formed via a company formations agent

If you originally registered your company online through a company formation agent, such as Your Company Formations, it will be very easy to retrieve your WebFiling authentication code by logging into your customer area on your formation agent’s website (here is a link to our customer area) where you will be able to see your authentication code listed along with your other company details. You can also find out what your code is by contacting your formations agent directly by email or phone to request your code.

Should your have expired, then you will need to go to the Companies House WebFiling portal, where you will need to log in and request a replacement code in the same way that has been described in the steps listed above.

What is the Companies House WebFiling Authentication Code?

When a new company is registered in the UK, they are issued with a special Companies House WebFiling authentication code. This code is made up of six alphanumeric characters – basically a mixture of letters and numbers that will be unique to your company.

Without your authentication code you will be unable to perform any online tasks using Companies House WebFiling, such as:

  • File your company’s confirmation statement or annual return
  • File your company’s annual accounts
  • File your company’s director or secretary changes and any other information you need to update Companies House with

Once you have successfully requested a new or replacement code, your WebFiling authentication code will be posted out to your company’s registered office address.

For a new company, you should receive your code within five days of your company formation date. Your authentication code is a security measure that ensures only authorised persons are able to access and change your company details.

    I searched high and low online about how to retrieve my authentication code. I could not find a link on my online Companies House account. Your blog, correctly identified that my formation agent online account may hold the code and that is exactly where it was. I am now able to file on time. Thank you.
