# Quotas for your Network 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 Network 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).

## Load balancer
<a name="load-balancer-quotas"></a>

Your AWS account has the following quotas related to Network Load Balancers.


| Name | Default | Adjustable | 
| --- | --- | --- | 
|  Certificates per Network Load Balancer  |  25  | [Yes](https://console.aws.amazon.com/servicequotas/home/services/elasticloadbalancing/quotas/L-52964454) | 
|  Listeners per Network Load Balancer  |  50  | No | 
|  Network Load Balancer ENIs per VPC  |  1,200 ₁ | [Yes](https://console.aws.amazon.com/servicequotas/home/services/elasticloadbalancing/quotas/L-23568085) | 
|  Network Load Balancers per Region  |  50  | [Yes](https://console.aws.amazon.com/servicequotas/home/services/elasticloadbalancing/quotas/L-69A177A2) | 
|  Targets per Availability Zone per Network Load Balancer  |  500 ₂, ₃ | [Yes](https://console.aws.amazon.com/servicequotas/home/services/elasticloadbalancing/quotas/L-B211E961) | 
|  Targets per Network Load Balancer  |  3,000 ₃ | [Yes](https://console.aws.amazon.com/servicequotas/home/services/elasticloadbalancing/quotas/L-EEF1AD04) | 

¹ Each Network Load Balancer uses one network interface per zone. The quota is set at the VPC level. When sharing subnets or VPCs, the usage is calculated across all tenants.

² If a target is registered with *N* target groups, it counts as *N* targets toward this limit. Each Application Load Balancer that is a target of the Network Load Balancer counts as 50 targets if cross-zone load balancing is disabled or 100 targets if cross-zone load balancing is enabled.

³ If cross-zone load balancing is enabled, the maximum is 500 targets per load balancer, regardless of the number of Availability Zones.

## Listener rules
<a name="listener-rules-quotas"></a>

The following quotas are for listener rules.


| Name | Default | Adjustable | 
| --- | --- | --- | 
| Rules per Network Load Balancer | 100 | No |

## Target groups
<a name="target-group-quotas"></a>

The following quotas are for target groups.


| Name | Default | Adjustable |
