.phd

.phd is a generic top-level domain designed around the academic title PhD, or Doctor of Philosophy. Google Registry markets it to doctorate holders, researchers and advanced scholars who want their academic identity visible in the domain itself.

The extension can suit personal academic sites, research portfolios, publications, dissertations and professional profiles. Google describes .phd as a domain for people who have earned the right to use the title, so the strongest and most responsible use is one that accurately reflects a real academic credential.

The current .phd Domain Registration Policy does not describe a documentary doctorate-verification procedure for ordinary registrations; its specific registration notice focuses on HTTPS. The domain itself should therefore not be treated as independent proof that the holder has a doctorate.

.phd is included in the HSTS preload list, so HTTPS is required.

VYR classifies .phd as open from the registration-process perspective, while content and branding should accurately represent academic credentials.
