    • The quota varies based on the resource type. This indicates that the maximum number of tags that can be added to a single resource depends on the type of the resource. You need to go to the Quota Center console to check whether you can adjust the quota for a type of resource.

    • After you apply for a quota increase for a type of resource and the application is approved, the new quota takes effect within one hour.

    • If you want to increase the quota for ECS instances, we recommend that you apply for a quota increase for ECS disks and ECS elastic network interfaces (ENIs) when you apply for a quota increase for ECS instances. The disks and ENIs are created together with ECS instances.

    Each tag key on a resource can have only one tag value. If you attempt to add a tag that has the same key as an existing tag, the value of the existing tag is overwritten.

    For example, the city:shanghai tag is added to a resource. If you add the city:newyork tag to the resource, the city:shanghai tag is automatically removed from the resource.

    Note

    • The number of policies that can be attached to a RAM user, RAM user group, or RAM role is not affected by authorization scope. In other words, you can apply the same number of policies whether you grant permissions on a single resource group or on your Alibaba Cloud account.

    • This topic lists only the default quotas for the items. The quotas of specific items are adjustable. To apply for a quota increase, go to the Quota Center page. You can configure quotas for a wide range of Alibaba Cloud services in Quota Center. For more information, see Services that work with Quota Center.
