When you registered your .AT domain, you had to enter a "Registrant." This information cannot just be changed in your Dynadot account as with most domain extensions. Instead, you must create a trade order. To do so, please follow these steps:

1. Sign in to your Dynadot account.
2. Select "Manage Domains" from the "My Domains" drop-down menu.
3. Find and click on the link for your actual .AT domain name.
4. Scroll down to the "AT Trade" box. You can begin your trade order on this page.
