Request your Companies House authentication code

Setting up a limited company is exciting! But the paperwork? Not so much. To request Companies House authentication code might seem like just another task to add to the list, but it’s quite straightforward to get your hands on one.

In this guide, we’ll walk you through how to get your authentication code and explain why you’ll need it.

What is a Companies House authentication code?

A Companies House authentication code is made up of 6 digits, and it’s key when it comes to updating your business activity online. 

It’s your digital equivalent to a company’s officer’s signature. But why do you need one? Well, it allows you to easily manage and update information about your company.

Without it, you won’t be able to:

• File your accounts
• File your confirmation statement
• Make changes to your company, like updating your address
• Close your company

So, now that we can agree it’s important, let’s find out how you can request one from Companies House.

How to request Companies House authentication code

If you’ve forgotten your code or need a reminder, here’s how you can get one:

1. Log in to Companies House 

Head to the Companies House website and sign in via their WebFiling service. If you don’t have an account already, you can create one here.

2. Find the authentication code section

Once you’re logged in, find the section for managing your authentication code. This will be under your account settings or company security.

3. Request a new code

Follow the on-screen prompts to request a new authentication code. You’ll need to fill out a form, but this should take no time at all.

4. Wait for your code

Companies House will send your code to your registered address or email. It should arrive within a few days. If you already have one, they’ll send you a reminder.

Why haven’t I received my Companies House authentication code yet?

Your code can take up to 5 working days to arrive. If you still haven’t received it after this time, check that your physical address and email address are correct. If they are, get in touch with Companies House.

How to use your authentication code

Once you have your code, you can use it to access your company’s online account and make updates. So, make sure you keep a record of it somewhere safe and don’t share it with anyone who isn’t authorised. 

You’ll need to share your code with your accountant so that they can file updates for you – like your annual company tax return.

You can also use it with third-party accounting software, but you’ll need to set up an online filing account first.
