.uk Domain: United Kingdom ccTLD Guide

Updated October 2026

.uk is the country-code top-level domain for the United Kingdom.

Overview

One of the most recognised national extensions in the world, widely used as .co.uk and, since 2014, as .uk directly.

The ISO country code for the UK is GB, but the internet uses .uk, which ISO lists as an exceptionally reserved code. A .gb ccTLD was reserved but never widely used, and it is closed to registrations.

Nominet runs .uk. Names can be registered at the second level (example.uk) or under .co.uk, .org.uk and similar endings.

Who can register

Generally open to registrants worldwide.

Second-level endings: Also .co.uk, .org.uk, .me.uk.

Before you buy a .uk name

• Check the renewal price as well as the first-year price. Our cost calculator shows what a name really costs over time.
• Make sure you meet the eligibility rules yourself, without relying on a trustee if you can avoid it.
• Search for trademarks and for the same name in .com.
• Say the name out loud: will people type it correctly?
