Internet Domains – Country-Code for the United Kingdom On the World Wide Web, many national sites use a country-code top-level domain (ccTLD). Which two-letter code is officially used for the United Kingdom?

Introduction / Context:
Country-code top-level domains (ccTLDs) help identify a website’s national association. Recognizing the correct code is useful for digital literacy, geo-targeted searches, and brand localization strategies.

Given Data / Assumptions:

• The question asks for the ccTLD used for the United Kingdom.
• We are selecting the two-letter Internet code used in domain names.
• Common real-world examples include .co.uk and .gov.uk.

Concept / Approach:
The official ccTLD for the United Kingdom is .uk. Although ISO lists the country code as GB for some contexts, the DNS system assigns .uk for UK web domains. Many second-level domains exist beneath .uk, such as .co.uk (commercial), .org.uk (organizations), and .gov.uk (government).

Step-by-Step Solution:

Verification / Alternative check:
Checking government or major news sites from the United Kingdom shows domains ending in .uk, confirming the correct code.

Why Other Options Are Wrong:

• GB: ISO code for Great Britain; not the ccTLD in practice.
• EN: Not a country code; might be misread as “England,” which is not used in ccTLDs.
• EG: Egypt’s ccTLD (.eg), not the UK.

Common Pitfalls:
Assuming ISO alpha-2 codes always match ccTLDs; the UK is a notable exception where .uk is used instead of .gb.

Final Answer:
UK
