Edit a domain’s CAA DNS record to get RapidSSL Partner certificates

Solution ID:    SO28449    Updated:    04/16/2018


To get RapidSSL certificates for your domain, update the CAA DNS Resource Record to state that RapidSSL is approved to issue certificates for your domain.

The registered domain owner must update the CAA DNS zone file to add RapidSSL as an approved CA in a CAA DNS record. You can find information about how to access and edit the CAA DNS zone file for the domain by contacting the domain’s registrar.

  1. Open the CAA DNS zone file for editing.
  2. Under $ORIGIN rapidssl.com, add the line:  CAA 0 issue “rapidssl.com” as follows:
    $ORIGIN rapidssl.com
    . CAA 0 issue "rapidssl.com"
  3. On your certificate's Order Information page in RapidSSL Partner Center, click Recheck CAA. If the check succeeds, your order is processed normally.

The single CAA record applies to all web servers in your domain, for example www.rapidssl.com, shop.rapidssl.com, checkout.rapidssl.com, etc.

Update: With Digicert's acquisition of Symantec Website Security and related PKI solutions, Certification Authority Authorization (CAA) records can now include digicert.com. This authorizes DigiCert to issue DigiCert, Symantec, Thawte, GeoTrust, and RapidSSL certificates for domains that contain such CAA records.

Do you already have a CAA Resource Record authorizing RapidSSLt to issue certificates for yourdomain.com (yourdomain.com CAA 0 issue "rapidssl.com")? Then, you don’t need to modify your existing CAA RR, nor do you need to create an additional CAA RRs for yourdomain.com. With that record you authorize DigiCert to issue your RapidSSL brand certificates for that domain plus all the other DigiCert certificate brands (DigiCert, Symantec, Thawte, and GeoTrust).

What is CAA?
