Your AWS account has default quotas, formerly referred to as limits, for each AWS service. Unless otherwise noted, each quota is specific to an AWS Region. You can request increases for some quotas, and other quotas can't be increased.
To view the quotas for AWS Clean Rooms, open the Service Quotas console
To request a quota increase, see Requesting a Quota
Increase in the Service Quotas User Guide. If the quota isn't yet
available in Service Quotas, use the Service limit increase
form
