Once your domain name is verified on a ChatGPT Plus account, there’s typically no need for re-verification for the same domain, unless you modify your settings or encounter issues with the initial domain verification. Adding a ChatGPT Team workspace does not affect the status of your domain’s verification.
However, it’s important to note that, currently, a domain can be verified by only one account at a time. If you intend for your domain to be exclusively verified and utilized within the Team workspace, you will need to remove it from your Personal account and proceed with verification under the Team account.
