AWS ACM Certificate Manager

Manage AWS Certificate Manager certificates

About AWS ACM Certificate Manager

Our AWS ACM Certificate Manager tool helps you check and manage SSL/TLS certificates provisioned through AWS Certificate Manager. Verify ACM certificate status, expiry dates, domain validation methods, and import or export certificate data for your AWS services including CloudFront, ALB, and API Gateway.

How to Use

1Enter the domain name associated with your ACM certificate.
2Click Run to fetch the ACM certificate details and status.
3Review the results showing validation status, expiry, and associated AWS resources.

Use Cases

•Verify ACM certificate validation status before deploying to CloudFront
•Monitor ACM certificate expiry for ALB and API Gateway integrations
•Check domain validation method (DNS or email) for ACM certificates

Frequently Asked Questions

AWS Certificate Manager (ACM) is a service that lets you provision, manage, and deploy public and private SSL/TLS certificates for use with AWS services. ACM handles certificate renewals automatically for integrated services.

ACM validates domain ownership through DNS (adding a CNAME record) or email validation. Once validated, ACM automatically renews certificates before expiry as long as the validation configuration remains in place.

ACM certificates cannot be exported and used outside AWS. They are designed to work exclusively with AWS integrated services like CloudFront, ALB, API Gateway, and Elastic Beanstalk.

No — nothing outside your AWS account can, since listing requires your credentials. The page works in the other direction: given your domain and region it writes the exact commands that request and inspect certificates, which you run with your own authenticated CLI. If you need a listing, the console or the list-certificates call with your credentials is the place.

Because most sites end up needing subdomains, and adding the wildcard at request time costs nothing while adding it later means a second certificate and a second validation. The generated command requests your apex plus one wildcard level together under a single validation. If you know you will never use subdomains, drop the extra name — the workflow is otherwise identical.

Usually minutes once the CNAME resolves, bounded by DNS propagation rather than by AWS. If a request sits pending for hours, the record is wrong: check the exact name and value ACM shows against what you published, watching for nameservers that have not picked up the change. ACM retries on its own, so fixing the record is the only action needed.

The one serving your traffic. An ACM certificate attaches only within its own region, so a certificate requested elsewhere cannot front your load balancer — CloudFront is the special case, requiring the certificate in us-east-1. When in doubt, request where the resource lives; a second regional copy later is cheap, while a mismatched one is useless.

DNS-validated ones do, as long as the validation CNAME stays published — which is the quiet argument for DNS over email validation. ACM handles the renewal and, for managed integrations, the deployment. Keep the CNAME in place permanently rather than removing it after issuance, or the first renewal will stall exactly when you have stopped watching.

What the Workflow Covers

Enter a domain and region and this page writes the AWS Certificate Manager workflow for it: the request command, the status command, and what validation requires. It generates commands from your input — it has no AWS credentials and cannot see your account, so it never pretends to list your certificates.

1Request the certificate with the generated command, which asks for your domain plus a wildcard alongside it, using DNS validation in your chosen region. DNS validation is the right default because it renews without depending on your web traffic.
2Add the validation CNAME ACM shows you. ACM proves domain control through that record, then issues automatically — there is no manual approval step once the record resolves, so a request stuck pending almost always means the record is missing or misspelled.
3Track it with the describe command, substituting the ARN from the request output. The same command serves later whenever you need expiry or status for that certificate.

Region matters and is baked into every command: ACM certificates live in one region and can only attach to resources that use the same one. Request in the region your load balancer or distribution serves from, or you will hold a valid certificate you cannot attach.

Tips & Best Practices

•Use AWS ACM for automated certificate management on AWS services
•Enable ACM auto-renewal to prevent certificate expiry
•Verify ACM certificate deployment across all load balancers and CloudFront distributions
•Monitor ACM certificate status for issues and failures
