What is your Nominet Tag (IPS Tag)?

What is an IPS tag?

The IPS tag is required on all .UK domain names by Nominet, the .UK domain name governing body. It’s used to identify the registrar associated with a specific .UK domain name. Every UK registrar has it’s own unique IPS tag.

How can I check the IPS tag on my domain?

To find out which IPS tag your domain currently has set, you’d need to perform a WHOIS lookup on the domain name. A WHOIS will return the registrar information, along with the domain name’s registration and expiry date, nameserver information and it’s registration status.

An example WHOIS lookup is shown below – in this case, the Registrar is 20i Ltd and uses our IPS tag ‘STACK’:

  Domain name:

    Data validation:
        Nominet was able to match the registrant's name and address against a 3rd party data source on 31-Jul-2018

        20i Ltd [Tag = STACK]

    Relevant dates:
        Registered on: 01-Jan-2017
        Expiry date:  01-Jan-2027
        Last updated:  03-Jan-2023

    Registration status:
        Registered until expiry date.

    Name servers:

How do I transfer a domain name to 20i using the IPS tag?

To transfer domain names ending with .uk, you'll first need to contact your current provider and request they change the tag to STACK. Once the tag change has been completed you'll be able to complete the transfer over to us.

If you're having any problems with changing your tag we recommend contacting Nominet.
