Area Code 42 – Villa Clara Province

Geographic Overview

The +53 42 country calling code and area code combination is assigned to the Villa Clara Province in central Cuba. This geographic area code covers the provincial capital, Santa Clara, along with other key municipalities such as Sagua la Grande, Placetas, Camajuaní, and Ranchuelo. As a geographic prefix, it is tied to the PSTN infrastructure of the region, serving both fixed-line residential and business subscribers within the province.

Dialing Formats

When calling a fixed-line number in Villa Clara from abroad, the international format is: +53 42 XXX XXXX (or +53 42 XXXXXXX depending on the local number length, typically 7 digits after the area code). From within Cuba, callers must dial the national trunk prefix 0, followed by the area code and the subscriber number: 0 42 XXX XXXX. For example, a local call from Havana to a number in Santa Clara would be dialed as 0 42 123 4567. When dialing internationally, the Cuban country code +53 replaces the trunk prefix, so the same number would be dialed as +53 42 123 4567.

Regulatory and Technical Notes

Cuba's national numbering plan is administered by the Ministry of Communications (MINCOM) and the telecommunications monopoly ETECSA. The 42 prefix is a geographic National Destination Code (NDC) that routes calls to the Villa Clara PSTN exchange. As of recent years, there have been no overlay codes for this area, meaning 42 remains the sole geographic code for the province. Fixed-line numbers in Cuba are not portable between geographic areas, so a number with the 42 prefix will always be associated with Villa Clara. For international callers, it is essential to verify the correct number of digits, as some older numbers may have fewer digits. ETECSA has been gradually expanding its fixed-line network, and some rural areas may have shorter local numbers, but the standard format is 7 digits after the area code.

Caller Instructions

For international callers: dial your country's exit code (e.g., 011 from the US, 00 from most European countries), then 53, then 42, followed by the local 7-digit number. For example, to call a number in Santa Clara from the US, you would dial 011 53 42 123 4567. For callers within Cuba, simply dial 0, then 42, and the local number. If you are calling from a mobile phone in Cuba, you may need to include the trunk prefix 0, but some mobile networks allow direct dialing of the area code and number. Always check with your service provider for the most accurate dialing instructions.
