About .bio

The .bio domain is a generic top-level domain for biographical content and personal or professional profiles. It is sponsored by Identity Digital Limited, a registry services company based in Bellevue, Washington, United States. Originally delegated in 2014 to Starting Dot Limited, the domain was transferred to Afilias Limited in 2019 and is now managed under the Identity Digital umbrella. There are no specific geographic or eligibility restrictions for registration, making it open to anyone interested in creating a personal website, résumé, or biography page. The name 'bio' is short for biography, which directly communicates the purpose of the domain to visitors. The registry offers standard DNS services and supports RDAP for domain registration data access. The .bio extension is a straightforward choice for individuals looking to establish a dedicated online identity.
