How can I change the IPS TAG of my and domains?

If your and 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 and 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 or in this article.
