UDAI, Auth & EPP Codes

New Zealand domains have a UDAI (Unique Domain Authentication Identifier) - a randomly generated 8 character string unique to each NZ domain. The main purpose of a UDAI is to authorise the transfer of a domain from one registrar to another. A UDAI is initially generated when a domain is registered, although a new UDAI can be requested at any time.

International domains often use an Auth Code or EPP Code, which is very similar to a UDAI.

Having a valid UDAI or Auth Code gives a person virtually complete control over the domain name. Keep this in mind before passing the UDAI onto anyone else as they can potentially take over complete ownership of your domain.

Steps to Request a UDAI or Auth Code

Registrars are required to provide your UDAI upon request. SiteHost does not store the UDAI for your domain, but provides a method for you to request a new UDAI which will be generated and sent to the domain registrant email address.

  1. Go to the Domains module in the SiteHost Control Panel.
  2. Select the domain you want to request the code for.
  3. Click the Request UDAI or Request Auth Code action button (top/right).
  4. The domain and Registrant email address will be shown.
  5. Click the Request New UDAI or Request Auth Code button to confirm.
    • Each time you request a UDAI (.nz domains) the system will actually generate a completely new UDAI - making any previous UDAI for the domain invalid and unusable.
  6. The code will be emailed to the Registrant email address within a few minutes.
    • If the email does not arrive please double-check the Registrant email used for the domain and make sure you check the Spam folder in the email account. If you still cannot locate the email then contact us for help.
