The .BOOKING top-level domain (TLD) is used for websites related to hotel, lodging, and accommodation reservations. It was launched in 2015 and is a closed domain, which means it is only available for registered partners of Booking.com, the owner of the domain zone. This means you cannot directly register a domain name in the .BOOKING zone as you would in other open domain zones.

Using the .BOOKING domain can strengthen your business's brand and make it more recognizable in the tourism and hospitality industry. Additionally, using this domain zone can improve your website's search engine positioning due to its informative and relevant representation of the site's theme. To register a domain in the .BOOKING domain zone, you need to be a registered partner of Booking.com.

If you are a hotel or lodging owner and wish to use the .BOOKING domain for your website, you can join Booking.com's partnership program and gain access to registering a domain name in the .BOOKING zone.
