About Cuba Calling Code
Cuba's international dialing code is +53. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Cuba from another country. Cuba is located in North America.
Country calling codes (also known as ISD codes or dialing codes) are telephone numbering plan prefixes defined by ITU-T standards E.123 and E.164. Each country is assigned one or more unique prefixes to facilitate international direct dialing.
Where the +53 Calling Code Is Used
The country code +53 is assigned to Cuba, located in Caribbean, with the capital Havana. This code is part of the international telephony numbering plan and is used for all calls made to Cuba from outside the country.
When you see a phone number written as +53 ..., the +53 prefix tells your telephone network to route the call to Cuba's national telephone network. After the country code, you dial the local area code (dropping any leading 0) and the subscriber number. The same format applies whether you are calling a landline or a mobile phone.
Country codes are allocated by the International Telecommunication Union (ITU-T Recommendation E.164) and are grouped by geographic region. Calling codes starting with 5 are generally assigned to the region around Cuba, in Caribbean. When a phone number is stored internationally, the leading zeros of the domestic area code are omitted after the country code — this is why you will often see numbers written as +53 followed directly by the area code and number.
Cuba Phone Number Formats
Phone numbers in Cuba follow the ITU E.164 international format: country code + area code + subscriber number. Below is the general structure used for both landlines and mobile numbers.
📱 Number Structure
- International format: +53 [area code] [subscriber number]
- From abroad: exit code + +53 + local number (drop the trunk prefix 0)
- Within Cuba: dial the local number directly
Most countries use a closed or open telephone numbering plan. In an open plan, the length of local numbers varies and the trunk prefix (usually 0) is dropped when dialing internationally. In a closed plan, all national numbers have a fixed length regardless of area. When dialing Cuba from abroad, always replace the leading trunk zero with the country code +53.
Time Zone in Cuba
Cuba is in the America/Havana time zone, which is UTC-05:00 relative to Coordinated Universal Time (UTC). If you are calling from a different time zone, remember to account for the time difference when scheduling your international call.
When planning a call to Cuba, the time difference matters: a good time to reach businesses in Havana, the capital, during their working hours may be early morning or late evening in your own time zone. Many international callers use the UTC offset as a quick reference to avoid calling in the middle of the night.
Some countries observe daylight saving time (DST), which shifts the local clock by one hour during summer months. If Cuba uses DST, the effective offset changes twice a year — check the current UTC offset before dialing if your call is time-sensitive. For most purposes, however, the standard offset shown above is sufficient.

Example: Calling Cuba Numbers in Practice
Here is how a typical call to Cuba works, depending on where you are calling from:
🌍 From the United States or Canada
- Dial the US/Canada exit code 011
- Dial the Cuba country code +53
- Dial the local number (area code + subscriber number, without the trunk prefix 0)
Example: 011 +53 [area code] [number]
🌍 From the United Kingdom or Europe
- Dial the international access code 00 (or use the + symbol on mobile)
- Dial the Cuba country code +53
- Dial the local number
Example: 00 +53 [area code] [number], or +53 [area code] [number] from any mobile phone
If the number you are calling has a domestic trunk prefix (often 0) in front of the area code, omit it when dialing from abroad. The country code +53 replaces the trunk prefix entirely.
