📍 Geographic Location of Granma Province
Geographic Overview
The +53 23 country code and area code combination is assigned to the Granma Province of Cuba, an administrative region located in the southeastern part of the island. Granma is one of Cuba's 15 provinces and is named after the yacht that carried Fidel Castro and his revolutionaries from Mexico to Cuba in 1956. The province's capital and largest city is Bayamo, a historic city known for its role in the Cuban War of Independence. Other significant urban centers within the Granma Province include Manzanillo, a port city on the Gulf of Guacanayabo, and Media Luna, Pilón, and Niquero, which are coastal municipalities. The area code 23 covers the entire province, including both urban and rural zones.
Dialing Formats
When calling a landline or mobile number within the Granma Province from abroad, the international format is +53 23 XXX XXXX, where 'XXX XXXX' represents the local subscriber number. For domestic long-distance calls from other provinces in Cuba, callers must dial the trunk prefix '0' followed by the area code and subscriber number: 0 23 XXX XXXX. Local calls within the same area code can be made by dialing only the seven-digit subscriber number, without the area code or trunk prefix.
Numbering Details
All numbers under the 23 prefix are part of Cuba's national numbering plan, which follows the ITU-T E.164 recommendation. The total length of a Cuban national significant number is eight digits, including the area code. Therefore, local numbers in Granma are seven digits long. The prefix is allocated to fixed-line services, primarily operated by the state-owned telecommunications company, Empresa de Telecomunicaciones de Cuba S.A. (ETECSA). While mobile services in Cuba use separate non-geographic prefixes (e.g., 5X), the 23 code is reserved for geographic fixed-line numbers. As of the latest available data, there are no overlay codes planned for Granma, meaning the 23 prefix remains the sole geographic code for the province.
Caller Instructions
For international callers, always replace the '+' with the appropriate international access code from your country (e.g., 011 from the US, 00 from most European countries) when dialing from a landline. For example, to call a number in Bayamo, you would dial 011 53 23 123 4567 from the United States. Mobile phone users can typically dial +53 23 123 4567 directly. For domestic callers outside Granma, remember to include the trunk prefix '0' before the area code. When calling from within Granma, simply dial the seven-digit local number.
Important Considerations
Cuba's telecommunications infrastructure is still developing, and international call quality may vary. Additionally, due to the U.S. embargo, direct dialing from the United States may be restricted; callers might need to use alternative services or third-party providers. Always verify the current dialing procedures with your telecom operator, as routing and access codes can change.
