This relates to transferring a .UK TLD (top level domain)

When you are transferring domains from one registrar to another, they always ask for the IPS-TAG. This is the unique name for the registrar (domain name management) you are transferring to.

Some tips for your top level domain name

.uk –  The shorter domain for everyone.
.co.uk – The orginal domain for British business.
.org.uk – For your cause.
.me.uk – When it’s all about you.

So, here is a list of IPS-TAGS for the most common registrars out there in the UK:
