Custom domain - A DNS zone already exists on NS1

The reason for this error (“A DNS zone for this domain already exists on NS1”) is one of two things. Either some other company has already configured a DNS zone for this domain at NS1 or a zone has previously existed on Netlify. In either of these cases, a new zone cannot be created. We are not the only company that builds our services using NS1 as a component. For example, Squarespace also uses NS1, so if you’ve configured this domain at Squarespace (or a similar service) that will prevent us from doing the same.

There are two solutions for this.

  1. Fastest & Easiest Solution: Set up external DNS by creating an A and CNAME record following the attached guide. This will unblock you immediately.
  2. If you’ve used the domain with a different service, you’ll need to contact that service to have them remove the configuration for this domain at NS1. NS1 won’t tell us who the other company is that already configured this domain with their service. This means you will need to determine which other services you have used for DNS service for this domain and contact that company to get this removed.

We hope this helps! Please let us know if you have any follow-up questions.
