.uk

Registrations under the United Kingdom's country code were, for most of its history, made at the third level beneath .co.uk rather than directly under .uk. Nominet UK opened direct second-level registration in 2014, and uptake has grown substantially since; the namespace now holds roughly 11 million domains. In contrast to several large European ccTLDs, .uk imposes no local-presence condition and accepts registrants worldwide. The extension was delegated in 1985, placing it among the earliest country codes assigned.
