Cuba numbering plan & how to dial
Cuba uses an open numbering plan under country code +53. After the country code, a 2-digit area or mobile prefix is followed by a 7-digit subscriber number, giving a 9-digit national number. Domestic numbers are often written with a leading trunk "0" that is omitted when dialing Cuba from abroad.
Cuba has 65% internet penetration and is served by 1 major mobile networks (ETECSA (Empresa de Telecomunicaciones de Cuba)). VoIP is restricted and MINCOM (Ministerio de Comunicaciones de Cuba) licenses only approved operators. The local currency is CUP and the primary language is Spanish, which shape IVR prompts, SMS content, and business-hours handling.
Numbering across the Americas mixes the North American Numbering Plan (+1) with national E.164 plans, so mobile and fixed-line prefixes vary from country to country.
Skipping the exit code
From the US you must dial 011 before the +53 country code to reach Cuba.
Keeping the national trunk "0"
If a Cuba number is written with a leading 0 for domestic use, omit that 0 after the +53 country code when calling from abroad.
Ignoring the time difference
Cuba runs on UTC-5. Check local hours before dialing so calls don't land outside business time.
Using non-compliant routes
VoIP into Cuba is restricted by MINCOM (Ministerio de Comunicaciones de Cuba); grey routes are blocked or dropped, so licensed termination is required for reliable delivery.
