CAA Records, short of Certificate Authority Authorization, is the record that specifies which (CA) Certificate Authorities can issue SSL certificates for a domain name.

Important: For your records to work, your Name Servers should be set to one of the following two options, which determine where you should add the DNS Records:

  • – DNS is managed on Dashboard
  • – DNS is managed on cPanel

The numbers may vary on the hosting name servers depending on your hosting plan. This information is emailed to you when you first purchase a plan.

If you have a third-party name servers, the DNS Records should be added on that provider’s end.

Characteristics of the CAA Records

The CAA Records have two fields that are unique to them – the flags and the tags:


The flags determine how the CAA record is interpreted, and can be in two default states:

  • 1 (critical) – The CA can’t use the record if it doesn’t understand the properties of the record, and won’t proceed to evaluating another records in the zone.
  • 0 (non-critical) – The CA can use the records regardless if it understands it. If it’s not valid, it can proceed with evaluating other records in the zone.


The tags determine which actions the Certificate Authority can make when issuing the certificates. There are three of these tags, and they have the following functions:

  • issue – Authorizes the CA to issue non-wildcard certificates for the root domain and any subdomain.
  • issuewild – Authorizes the CA to issue wildcard certificates for the root domain.
  • iodef (Incident Object Description Exchange Format) – Provides the domain registrant the ability to receive information in case of SSL failure or other certificate related issues.
