According to ALLCITYCODES.COM, the area code of Cuba is +53, which was adopted in 1996 when the country switched to the ITU-T E.164 numbering system. The code is divided into two parts: ‘+’ and ‘53’. The ‘+’ indicates that the number is international and the ‘53’ identifies the country as Cuba. In Cuba, telephone numbers are usually seven digits long and are divided into four parts: a two-digit area code, a two-digit exchange code, a three-digit line number and an optional one-digit service code. Area codes indicate the geographic region of the phone number and are used to route incoming calls to their respective locations. Exchange codes identify specific local calling areas within each geographic region, while line numbers identify individual subscribers within each local calling area. Service codes are used to access special services such as voicemail or mobile networks. Cuba has seen advances in telecommunication services over recent years, with mobile phone penetration rates increasing rapidly across both rural and urban areas of the country. This has been driven by increased investment in infrastructure improvements as well as technological advancements such as 4G networks being rolled out in major cities across Cuba. As such, it is important for businesses operating within Cuba to ensure they are using the correct area codes when making calls within the country as well as when communicating with other countries around the world. The Cuban government operates on a single-party system, with the Cuban Communist Party (PCC) as the only legally sanctioned political party. The PCC holds a monopoly on political power in Cuba, with all government officials and representatives being members of the PCC. The Cuban Constitution dictates that the country is to be led by a single-party socialist state under the guidance of Marxist-Leninist ideology. This includes a commitment to socialism, national sovereignty and self-determination, social justice and equality, and international solidarity. The government is further divided into executive, legislative, and judicial branches of power. Executive control is held by the Council of State which is led by the President while legislative authority belongs to the National Assembly of People’s Power which consists of 614 representatives from across Cuba’s provinces.
