Enhanced Domains

With enhanced domains, all URLs across your org contain your company-specific My Domain name, including URLs for your Experience Cloud sites, Salesforce Sites, Visualforce pages, and content files. With no instance names, enhanced My Domain URLs are easier for users to remember and remain stabilized when your org is moved to another Salesforce instance. Because enhanced My Domains meet the latest browser requirements, they're the future standard.
Available in: both Salesforce Classic (not available in all orgs) and Lightning Experience
Available in: Group, Essentials, Professional, Enterprise, Performance, and Unlimited Editions

We recommend enhanced domains for all Salesforce orgs. They are required in Summer ’22.

Enhanced domains are available in Hyperforce orgs and in orgs with a deployed My Domain routed through Salesforce Edge Network. They aren’t available in Developer Edition or in scratch orgs. For more information on the availability of this feature, join the discussion on the My Domain and Enhanced Domains group in the Trailblazer Community.

Note

Here are some example URL formats for orgs with a deployed My Domain with enhanced domains.
