United Kingdom

The United Kingdom is identified by the ISO Alpha-2 code GB and Alpha-3 code GBR, used in international shipping, data systems, and statistical processing. Its primary calling code is +44, required when dialing UK numbers from abroad. The country-code top-level domain (ccTLD) is .uk, widely used for domain registration and localized web presence. The official currency is the British Pound Sterling (GBP, symbol £), a major global reserve currency frequently traded in forex markets. In financial contexts, GBR and GBP are critical for transactions, banking operations, and invoicing. Together, these identifiers ensure accurate communication, data exchange, and commercial activity within the United Kingdom.
