Custom Domain: Another site is already using this domain


We’re trying to migrate our documentation site ( from Postman to a new site hosted on Netlify (currently at We have added the CNAME record on our DNS but when trying to add the custom domain we are receiving ‘Another site is already using this domain’. I presume this is because Postman use Netlify to host their documentation sites, however we have removed the custom domain from Postman but we are still seeing the issue.

How can we proceed?

Many thanks

Hi, having read other similar cases we have pre-emptively verified our domain ownership by creating a TXT record for verified-for-netlify. with the value pointing to this point. I hope that is sufficient to help us, if it’s needed?

We solved this by transferring the project to another team.

Great! Thanks for the update @nesters2003.
