+> - [Updated](https://gitlab.com/gitlab-org/gitlab/-/issues/292086) in GitLab 13.8 to include public
+    email address.
+
+The **Seat usage** page lists all users occupying seats. Details for each user include:
+
+- Full name
+- Username
+- Public email address (if they have provided one in their [profile settings](../../user/profile/index.md#profile-settings))
+
+The Seat usage listing is updated live, but the usage statistics on the billing page are updated
+only once per day. For this reason there can be a minor difference between the seat usage listing
+and the billing page.
