Area Code 24 – Holguín Province

Geographic Overview

Country code +53 is assigned to Cuba under the international numbering plan ITU-T E.164. The national destination code (NDC) 24 corresponds to the province of Holguín, located in the eastern region of the island. This geographic area code covers the city of Holguín, the provincial capital, as well as surrounding municipalities such as Banes, Mayarí, Moa, and Gibara. The province is known for its industrial activities, including nickel mining and agriculture, as well as tourism along its northern coast.

Dialing Formats

When calling a fixed-line subscriber in Holguín from abroad, the international format is: +53 24 XXX XXXX, where +53 is the country code, 24 is the area code, and the remaining seven digits constitute the subscriber number. For example, a local number might be dialed as +53 24 456 7890. From within Cuba, callers must dial the national trunk prefix 0 before the area code, resulting in the format 0 24 XXX XXXX. If you are physically within the Holguín province and calling another local fixed-line number, you may be able to dial only the seven-digit subscriber number, depending on the specific local dialing procedures. However, due to network modernization, it is recommended to use the full national format to ensure connectivity.

Administrative and Regulatory Context

The Cuban telecommunications infrastructure is managed by the state-owned enterprise ETECSA (Empresa de Telecomunicaciones de Cuba S.A.). Geographic area codes are assigned based on provincial boundaries, and fixed-line numbers are generally tied to physical locations. The Holguín code 24 is used exclusively for fixed-line services; mobile numbers in Cuba use separate non-geographic prefixes, such as 5, 6, and 7, and are not associated with a specific province.

Caller Instructions

For international callers, always replace the leading zero of the national dialing format with the +53 country code. For example, a national number 0 24 456 7890 becomes +53 24 456 7890 when dialed from abroad. Ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries) before dialing +53. For local callers within Cuba, the national trunk prefix 0 is required when dialing from a different province or from a mobile phone. Overlays are not currently in use for Holguín, so the 24 area code is unique to this province.

Practical Considerations

When calling Holguín, be aware that international call rates may apply, and the call quality can vary depending on the route. For businesses or individuals requiring reliable contact, it is advisable to confirm the correct number format with the recipient, as fixed-line numbers in Cuba are typically 8 digits long (area code + subscriber number). The subscriber number portion is always 7 digits, and the area code is 2 digits, making a total of 9 digits for the national significant number (NSN).
