Saint Lucia

Saint Lucia uses the calling code +1, part of the North American Numbering Plan, for international phone calls. Its ISO codes are LC (two-letter) and LCA (three-letter), used in global shipping, data systems, and international banking. The country-code top-level domain (ccTLD) is .lc, essential for local business websites and digital branding. The official currency is the East Caribbean Dollar (XCD), abbreviated for financial transactions and trade. Together, these identifiers support practical operations ranging from dialing a Saint Lucian number and registering a .lc domain to processing payments or verifying entities in economic and regulatory contexts. Understanding these codes is vital for telecom, e-commerce, and business compliance in the Americas region.
