How can I change the IPS TAG of my .co.uk and .org.uk domains?
If your .org.uk and .co.uk domains are managed by SiteGround, you can change their IPS TAG from:
User Area -> My Account -> Domain Names -> Manage button -> Domain Name Tag
If your .org.uk and .co.uk domains are not registered by SiteGround but you need to change their TAG in order to initiate a domain name transfer, you should contact your current registrar and ask them to make the change. The domain name tag should be set to TUCOWS-CA before the transfer can be initiated.
Once the tag has been set to TUCOWS-CA, you can initiate the transfer from your User Area > Add services > Domain transfer > Get.
You can find more information about transferring your .co.uk or .org.uk in this article.
