I'm setting up a new organization and have reached the default limit of five accounts. I submitted a quota increase request, but it has remained in CASE_OPENED status. I'm used to basic quota changes, such as account limits or CPU cores, being approved within minutes, so I'm trying to estimate whether I should wait or continue with another task and risk having to return to the organization setup later.

Check the underlying support case rather than relying only on the quota page. I had a request sit in CASE_OPENED for several days even though the increase had actually been approved after a few hours. The status on the quota page never updated, but the support ticket showed the real result.
Account limits are generally among the simpler quotas, so I’d expect an automated approval when the requested increase is modest. Still, manual reviews can take days or even longer depending on the service and region, especially when the account is brand new.
The request method can make a difference. Self-service requests submitted through the Service Quotas page or CLI are often much faster than opening a general support case. Modest increases are sometimes approved immediately, although new accounts may still require review.
You can keep working on the infrastructure that doesn’t depend on the extra accounts. In a multi-account setup, the provisioning code should be reusable across accounts, so preparing the organization, logging, security, and baseline configuration now may reduce the delay once the limit is raised.
I’ve already created the root, auditing, security, log-archive, and infrastructure accounts, which uses all five slots. I’m mainly blocked because the workload accounts need to be isolated, but I can continue preparing the reusable configuration in the meantime.
It depends on the quota and the account. Many requests are automated, but new accounts and certain resources may be evaluated using account age, billing history, spending, region, and support level. A new account with little history can be routed for manual review, which may take considerably longer than a few minutes.

I submitted it through the CLI with request-service-quota-increase, so hopefully it gets treated as a self-service request.
