# Increase the quotas for SSL/TLS certificates
<a name="increasing-the-limit-for-ssl-tls-certificates"></a>

There are quotas on the number of SSL/TLS certificates that you can import into Amazon Certificate Manager (ACM) or upload to Amazon Identity and Access Management (IAM). There also is a quota on the number of SSL/TLS certificates that you can use with an Amazon Web Services account when you configure CloudFront to serve HTTPS requests by using dedicated IP addresses. However, you can request higher quotas.
