Area Code 45 – Matanzas Province

Overview of Area Code +53 45

Area code 45 is a geographic National Destination Code (NDC) assigned to the province of Matanzas in Cuba. It covers the city of Matanzas, the provincial capital, as well as surrounding municipalities including Cárdenas, Colón, Jagüey Grande, and the Varadero resort area. As a fixed-line code, it is used for PSTN (Public Switched Telephone Network) services, including landlines and some fixed wireless terminals.

Geographic Coverage and Administration

The code falls under the jurisdiction of the Cuban telecommunications administration, ETECSA (Empresa de Telecomunicaciones de Cuba S.A.), the state-owned monopoly. Matanzas Province is located on the northern coast, east of Havana, and is known for its industrial ports and tourism. The numbering area is contiguous, meaning that all fixed-line numbers within the province share the same NDC, regardless of the specific municipality.

Dialing Formats

For local calls within the Matanzas area, callers must dial the seven-digit subscriber number preceded by the area code. For example, to call a landline in Matanzas from within Cuba (outside the local area), the format is:

• National dialing: 45 XXX XXXX (where X represents the subscriber digits)
• International dialing from abroad: +53 45 XXX XXXX

Note that the leading trunk prefix '0' is not used in international format. For example, a number in Matanzas might be +53 45 123 4567. When calling from a mobile phone in Cuba, the same national format applies, but the call may be charged as a long-distance call if the caller is outside the province.

Overlay and Numbering Considerations

Currently, there is no overlay code for Matanzas; the province uses only NDC 45. However, as demand for fixed lines grows, ETECSA may introduce additional NDCs or expand the number length. Subscriber numbers are typically seven digits long, but some older lines may have fewer digits; always verify the complete number before dialing.

Caller Instructions

For callers within Cuba: dial 45 followed by the seven-digit number. For international callers: dial the international access prefix (e.g., 011 from the US, 00 from many countries), then Cuba's country code 53, then 45 and the subscriber number. Do not include any leading '0' that might appear in local listings.

For travelers visiting Varadero or Matanzas, using a local SIM or a VoIP service can reduce costs. Note that calls to Cuban landlines from abroad may be subject to international tariffs and potential restrictions due to US embargo regulations.
