Congo
The Republic of Congo is identified by the ISO 3166-1 codes CG (alpha-2) and COG (alpha-3), used in international databases, shipping manifests, and financial systems. Its international calling code is +242, required when dialing into the country from abroad. The country-code top-level domain (ccTLD) .cg serves local website registration and digital branding. The official currency is the Central African CFA franc (XAF), shared with neighboring states and used for all domestic business and commercial transactions. Together, these identifiers facilitate global telecommunications, web presence, and financial operations for entities operating within this Central African nation.
