Adding Subject Alternative Names to your Multi-Domain (SAN) Certificate

DigiCert's Multi-Domain (SAN) Certificate allows you to reissue at any time to change or add names. Do this in your account by following these instructions:

  1. Generate a new CSR on your server. Most servers will require you to create a new CSR (including all Microsoft servers). Apache users can use the same CSR as long as they have the same private key that was created with it. See instructions for generating a CSR for help doing this.
  2. After logging into your DigiCert account, click on your certificate order number on the My Orders tab.
  3. Click the Add, Remove, or Change Domains button.

  4. Paste in your new CSR and a reason for the reissue.

  5. On the next step, you can select the names in the list and remove them or add new ones. You can also select which one should be the common name in the certificate and change the order of the names.

    If you need to use more names than you have purchased "name slots" for, simply add the names and enter your payment information in the next step.

  6. In most cases, the reissue must be approved by DigiCert support staff before your new certificate is issued. We can usually issue the new certificate within 30 to 60 minutes. If you do not receive your certificate in that time frame, or have specific questions about the process, please contact our 24 hour support for assistance.
