Unable to Delete ACM Certificate - No API Gateway, Custom Domain or Cloud Front Distribution Exists

Question

I am attempting to delete an ACM certificate from my AWS Account. This is not able to happen because it has some associated resources. Upon doing some research I found that this can happen because API Gateway or CloudFront will associate the certificate with its own Load Balancer. However, I do not have an API Gateway, Custom Domain, or CloudFront distribution active on this account.

Arns Look like:

```
arn:aws:elasticloadbalancing:us-east-1:250044486744:loadbalancer/app/prod-iad-1-az1-1-0/9c18104fa6102224
arn:aws:elasticloadbalancing:us-east-1:250044486744:loadbalancer/app/prod-iad-1-az2-1-103/b0fab4aa61af247a
arn:aws:elasticloadbalancing:us-east-1:250044486744:loadbalancer/app/prod-iad-1-az5-1-8/af057e0e069b45d2
arn:aws:elasticloadbalancing:us-east-1:392220576650:loadbalancer/app/prod-iad-1-cdws-71/3ef2e951b96d90d1
arn:aws:elasticloadbalancing:us-east-1:392220576650:loadbalancer/app/prod-iad-1-cdws-84/fa5b5f00887fe6f1
arn:aws:elasticloadbalancing:us-east-1:392220576650:loadbalancer/app/prod-iad-1-cdws-88/0fcd61b701b03141
```

What is the best way to resolve this? Are there other managed services that may associate my certificate with a load balancer that I am not thinking of? Will they eventually be deleted?

**Edit:** Just read your comment that those ARNs are from deleted API gateways, just double check one more time in us-east-1 if you have any API GW left, if not you can open a support case that you are not able to remove the ACM because of these ARNs.

The ARNs in your questions look like an API Gateway regional endpoint ARN. I have seen similar naming patterns for regional endpoints ALB ARNs.

I am sure you already know this but would like clarify for anyone reading in future, Deploying a Regional API endpoint creates an Application Load Balancer by API Gateway. The CloudFront distribution or Application Load Balancer is owned by API Gateway, not your account. The ACM certificate provided to deploy API Gateway is associated with the CloudFront distribution or Application Load Balancer.

Please follow the steps documented at: https://aws.amazon.com/premiumsupport/knowledge-center/acm-certificate-resources/

Everyone, wait a couple hours before submitting a support ticket.

I had the same issue today.  I was in the middle of writing up a support ticket and I was able to delete my cert by the time I was done writing it.  It probably took about 30-60 minutes for it to be disassociated.

Use the AWS Config service. For resource type select AWS ACM Certificate and then either select your certificate or enter the ARN of your certificate. Select Resource Timeline and focus on the configuration changes listed. Here you should be able to view the change details and you would be interested in the ones that call out Configuration.InUseBy.

All services which can use ACM you can find [here](https://docs.aws.amazon.com/acm/latest/userguide/acm-services.html).

As I remember certificate should show where is it used, but I can't confirm it right now.

Last advice :) you should avoid showing your account number because it's very sensitive data.
