Cuba numbering plan & how to dial
Cuba's numbering plan is open, sitting under country code +53: a 2-digit prefix followed by a 7-digit local number, 9 digits combined. Numbers are often shown with a leading "0" for domestic use — drop it when dialing in from abroad.
Mobile coverage in Cuba comes from 1 major networks — ETECSA (Empresa de Telecomunicaciones de Cuba) — with internet penetration at 65%. VoIP is restricted and MINCOM (Ministerio de Comunicaciones de Cuba) licenses only approved operators. Language (Spanish) and currency (CUP) both matter here for IVR, SMS, and scheduling support around local business hours.
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
Cuba calls from the US need 011 first, then +53 — the exit code isn't optional.
Keeping the national trunk "0"
Cuba numbers often show a domestic leading 0 — drop it once you've dialed the +53 country code from outside the country.
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
Because MINCOM (Ministerio de Comunicaciones de Cuba) tightly regulates VoIP in Cuba, only licensed routes deliver reliably; grey routes risk being blocked outright.
Restricted — MINCOM licensed only
Regulated by MINCOM (Ministerio de Comunicaciones de Cuba)
- ETECSA holds a state monopoly on telecommunications; independent VoIP providers cannot legally operate without government authorisation.
- International calls and VoIP are subject to strict government oversight under Cuban telecommunications decree-law.
- US trade sanctions (OFAC) require special licences for US-based operators providing services to Cuban entities.

FAQ
Calling Cuba — frequently asked questions
Cuba is in Americas. 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.
Yes — Cuba is one of 191+ countries in Twiching's directory, with virtual numbers, SIP termination, and Tier-1 routing available. It's part of the same platform used to manage numbers across every other country in the directory.
Where locally supported, yes — Twiching's Cuba numbers can send and receive SMS in addition to voice calls. That makes a single number usable for both two-way conversations and outbound notifications.
A full national Cuba number is 9 digits after the +53 country code — a 2-digit area or mobile prefix plus a 7-digit subscriber number. Getting this length right matters: too few or too many digits and the call simply won't connect.
No — Cuba isn't part of the NANP. It has its own country code, +53, under the international E.164 numbering system, which is why calls from the US need the 011 exit code first.
Cuba's area or mobile prefix is 2 digits, dialed right after the +53 country code and before the 7-digit subscriber number. Missing or mistyping that prefix is one of the most common reasons a call to Cuba fails to connect.
