Activation Code

What is an Activation Code?

A Dotpost Activation Code is a 16 character code unique to you. It links you with a trusted organisation (Sender) and allows them to send documents to you via Dotpost.

To register for Dotpost, a Sender must invite you and supply you with an activation code.

What does an Activation Code look like?

An activation code is made up of 16 letters and/or numbers, e.g. ABCD-5678-WXYZ-6543. It will be sent  to you by letter at your known address. The sender may call the code an Activation Code, a Dotpost Code or a Registration Code.



The activation code is single use and time sensitive. It should be used when received to ensure success.

If it is not used within its valid timeframe (30 days), it will expire and all unclaimed documents associated with the code will also expire.

How do I use this code?


Decision Tree
Do you (or the email you are using) have an existing Dotpost account?
  • Yes
  • No
  • Add Button
Each email address can only have one Dotpost account. However multiple senders can deliver documents to the account's inbox.

If you wish to allow the organisation that has sent you the activation code‍ to deliver documents to you via Dotpost, then they need to be added as a Sender to your account.


You can only add or modify senders via the web app. Senders cannot be accessed via the mobile apps.

  1. Go to
  2. Login using your email address and password.
    • If you have forgotten your password, you can reset it by following the Forgot your password link.
  3. Go to Senders
  4. Select Add New Sender
  5. Enter the activation code from your invitation and your postcode from the address on the invitation. i.e. You use the postcode from the address the invitation was sent to.
    • If there is no postcode click No Postcode and enter the full address as it appears on your invitation letter (even if it has mistakes).
  6. Click Add Sender
  7. The sender will now be shown in your Senders window.

This sender will now be able to send documents to you via Dotpost.


Existing Sender

If you already have this sender in your Senders list, it is important that you add this new activation code or you may not receive all the documents sent by this sender into your Dotpost inbox. This new activation code may relate to a different type of communication or to a different department that wishes to send you documents.

If you do not have an existing Dotpost account then you need to Register. Details of how to do this can be found in Getting Started‍. 


If you are attempting to use the code and Dotpost gives an invalid code message, it could be for the following reasons

  • the code has expired
  • the code has already been used
    • if you cannot login you may have not completed the registration process by clicking the link in the verification email
  • you are attempting to register but you already have an account. 
    • Follow the existing Dotpost account process above

Can I register if I don't have an Activation Code?

No, you need to receive an activation code from a sender. They will send the activation code to you via post.
