# Quotas for your Application Load Balancers
<a name="load-balancer-limits"></a>

Your AWS account has default quotas, formerly referred to as limits, for each AWS service. Unless otherwise noted, each quota is Region-specific. You can request increases for some quotas, and other quotas cannot be increased.

To view the quotas for your Application Load Balancers, open the [Service Quotas console](https://console.aws.amazon.com/servicequotas/home). In the navigation pane, choose **AWS services** and select **Elastic Load Balancing**. You can also use the [describe-account-limits](https://docs.aws.amazon.com/cli/latest/reference/elbv2/describe-account-limits.html) (AWS CLI) command for Elastic Load Balancing.

To request a quota increase, see [Requesting a quota increase](https://docs.aws.amazon.com/servicequotas/latest/userguide/request-quota-increase.html) in the *Service Quotas User Guide*. If the quota is not yet available in Service Quotas, submit a request for a [service quota increase](https://support.console.aws.amazon.com/support/home#/case/create?issueType=service-limit-increase).
