About Cayman Islands Calling Code

Cayman Islands's international dialing code is +1. This code is assigned by the International Telecommunication Union (ITU) and must be dialed before the local phone number when calling Cayman Islands from another country. Cayman Islands is located in North America.

ITU-T Recommendation E.164 is the standard behind the prefix +1: it gives every country a distinct international code so the global telephone network knows where to route a call. Cayman Islands holds +1, in Caribbean, and that code has to be dialed after your own exit code before any national number.

Where the +1 Calling Code Is Used

The country code +1 is assigned to Cayman Islands, located in Caribbean, with the capital George Town. This code is part of the international telephony numbering plan and is used for all calls made to Cayman Islands from outside the country.

When you see a phone number written as +1 ..., the +1 prefix tells your telephone network to route the call to Cayman Islands'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 1 are generally assigned to the region around Cayman Islands, 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 +1 followed directly by the area code and number.

The country code +1 is shared with United States, Canada, American Samoa, Anguilla, Antigua and Barbuda, Bahamas, Barbados, Bermuda, Dominica, Dominican Republic, Grenada, Guam, Jamaica, Montserrat, Northern Mariana Islands, Puerto Rico, Saint Kitts and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Sint Maarten, Trinidad and Tobago, Turks and Caicos Islands, US Virgin Islands, British Virgin Islands. After dialing +1, the following digits (area code + subscriber number) route the call to the correct country, so you must always include the full national number.

Cayman Islands Phone Number Formats

A Cayman Islands number follows the published pattern +1-345-XXX-XXXX. Whatever sits in front of it at home — usually a trunk 0 — is stripped for international calls, so you dial your exit code, then +1, then the national number with that zero removed.

Time Zone in Cayman Islands

Cayman Islands is in the America/Cayman 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 Cayman Islands, the time difference matters: a good time to reach businesses in George Town, 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 Cayman Islands 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.
