Get an authorisation code (UDAI)?

Please note: The ability to confirm if Authorisation Codes are valid is no longer available, a new one should be generated if a transfer fails with the provided Authorisation Code. The Authorisation Code will expire after 30 days.

There are also some terminology changes below based on the new set of .nz Rules and the launch of the new .nz Registry System.

What is an Authorisation Code (UDAI)?

An Authorisation Code is 16 characters in length and consists only of alphanumeric characters needed to transfer a .nz domain name from one domain name provider (registrar) to another. Some registrars also use Authorisation Codes to validate a change of registrant.
Authorisation Codes can be used only once.

Step 1: Check to see if you can generate an Authorisation Code directly.

Check your registrar to see if you can generate an Authorisation Code for your domain name directly.
Some registrars offer automated Authorisation Code generation. This function is usually accessed by logging into your account and going to your dashboard.

Step 2: Check your WHOIS registration details.

Check your WHOIS registration details using our WHOIS Lookup. Enter the domain name and click ‘Lookup’ to see your domain name details. Make sure they are up to date.

Check details in our WHOIS Lookup

Step 3: Request an Authorisation Code from your domain name provider.

To get an Authorisation Code, you may need to email or call your Registrar. They may also ask for evidence to prove that you are the registrant.

Registrars will only provide an Authorisation Code once they are confident it is the registrant requesting it. In our experience, registrars are unlikely to provide the Authorisation Code to any other party other than the registrant so it's preferable to email them from the registrant email address on the registration record.

Additional information

Please note: If your domain name displays a “client transfer prohibited” status on the WHOIS lookup service, you will need to request your current registrar to unset it first before you transfer the domain name.

You need to protect your Authorisation Code and make sure that you do not share it with anyone else unless specifically for the transfer of a domain name.

If you have any problems with requesting an Authorisation Code, please contact us at [email protected], attach any previous correspondence, and we will look into this for you.

Frequently Asked Questions: UDAI

Can an Authorisation Code be reused?

No, each Authorisation Code can be used only once. If a transfer fails with the provided Authorisation Code, a new one should be generated.

How long is an Authorisation Code valid for?

An Authorisation Code is valid for 30 days from the date of its generation.

What is the purpose of an Authorisation Code?

An Authorisation Code serves as a security measure to protect the ownership of a domain name. It ensures that only the rightful owner of the domain (the registrant) can transfer it to another registrar.

Do all registrars provide an option for automatic generation of an Authorisation Code?

No, not all registrars provide this feature. If your registrar doesn't offer automated generation, you will need to contact them directly to request an Authorisation Code.

What should I do if I receive a request to share my Authorisation Code?

You should never share your Authorisation Code with anyone unless it's for the specific purpose of transferring your domain name. It's the key to your domain name, and its security is vital for safeguarding your online identity. If someone requests your code and you're unsure why, it's best to contact your registrar or the Domain Name Commission directly for guidance.
