You can't extend or change the [13-month validity period](https://docs.aws.amazon.com/acm/latest/userguide/acm-certificate.html#validity.title) of ACM certificates.

However, you can request a certificate from a third-party certificate authority (CA) with a validity period that's greater than 13 months. Then, [import the third-party certificate to ACM](https://repost.aws/knowledge-center/import-acm-tls-ssl-certificate).

For more information, see [Importing certificates into AWS Certificate Manager](https://docs.aws.amazon.com/acm/latest/userguide/import-certificate.html).
