Add SANs to your multi-domain TLS/SSL certificate

Reissue your multi-domain TLS/SSL certificate to add subject alternative names (SANs)

DigiCert multi-domain certificates come with unlimited reissues. So, when needed, you can add SANS to your certificate. You can also change the common name, change the order of SANs, remove SANs, change SANs, and add SANs.

Standard SSL: You can't add SANs to a Standard SSL certificate. You can only replace the common.

Warning

Removing and changing domains on a multi-domain TLS/SSL certificate revokes the original certificate and any of its duplicate certificates. See Reissue a TLS/SSL certificate.

Add SANs to your multi-domain certificate

Step 1: Generate CSR

To add SANs to your multi-domain TLS/SSL certificate, you need to reissue your certificate. When reissuing a TLS/SSL certificate, you need to generate a new CSR. For more information about creating a CSR, see How to create a CSR (Certificate Signing Request).

Step 2: Sign in to your account

Sign in to CertCentral.

Step 3: Fill out the reissue form

  1. In CertCentral, in the left main menu, go to Certificates > Orders.

  2. On the Orders page, select the order number for the multi-domain or extended validation (EV) multi-domain TLS/SSL certificate you want to add SANs to.

  3. On the Order details page, in the Certificate Actions menu, select Reissue Certificate.

  4. On the Reissue Certificate for Order page, fill out the form:

    • Add your CSR

    • Add SANs

    • Select payment method, signature hash, and server platform

    • Add a reason for the reissue.

      Important

      You’re only charged if adding SANs occurs extra costs.

  5. When done, select Request Reissue.

Step 4: Complete domain control validation (DCV)

If adding new, unvalidated domains to the certificate reissue request, you need to demonstrate control over those domains before DigiCert can reissue the certificate. See Demonstrate control over domains on a pending certificate order.

Step 5: DigiCert reissues the multi-domain TLS/SSL certificate

When approved, we reissue and send the reissued certificate to the certificate contact via email. You can also download the reissued certificate from your account. See Download a certificate from your account.

Step 6: Install your reissued TLS/SSL certificate

Install and configure the new certificate. For more information about installing your certificate, see our SSL Certificate Installation Instructions & Tutorials page.
