Cayman Islands at a glance
The numbers and facts you need before you dial.
What is the country code for Cayman Islands?
The Cayman Islands belong to the North American Numbering Plan (NANP) under +1, with 345 as their dedicated area code. The practical upshot: from the US and Canada you place the call exactly as you would to another state or province — 1, then 345, then the seven-digit number — and the 011 international prefix never enters the picture. Only callers outside NANP add their own exit code ahead of 1 345.
Code +1 was assigned to Cayman Islands by the ITU under the E.164 plan. The “+” means “dial your local international exit code”; on a mobile, press and hold 0 to type it.
All four mean the same thing — they connect your call to Cayman Islands.
How to call Cayman Islands from anywhere
North American callers, treat Cayman like one more area code on your own plan — 1-345 and the number, no 011. Everyone outside NANP leads with their exit code, then 1 345.
Full example: +1 Flow XXX XXXX — drop the local leading 0 when calling from abroad.
Cayman Islands phone number format explained
A Cayman number wears the standard NANP shape: the 345 area code in front of a seven-digit subscriber number. On-island you can drop the area code and dial just those seven digits. Landlines and mobiles all share 345 — what tells them apart is the central-office prefix, the three digits sitting right after 345.
Landline
+1 345 XXX XXXX, a 7-digit subscriber number; locally, just the 7 digits.
Mobile
+1 345 XXX XXXX, with mobile prefixes clustered in ranges like 32x, 33x, 34x, 43x and 44x across Flow and Digicel. Portability is live, so the prefix narrows down but doesn't confirm the carrier.

Cayman Islands mobile network prefixes
The prefix after +1 tells you which network issued the SIM — though number portability means it no longer guarantees the operator.
Flow (Cable & Wireless / Liberty Latin America)
prefixes incl. 23x, 24x, 43x, 44x.
Digicel
prefixes incl. 32x, 33x, 34x.
Cayman Islands time zone
George Town runs on Eastern Standard Time (EST, UTC−5) every month of the year and never touches daylight saving. There's a twist worth flagging: when US clocks spring forward, Cayman stays put — so all summer the islands line up with US Central time, not Eastern, even though they sit on EST.
From 09:00–17:00, George Town blankets the full US East Coast business day in winter; in summer that same window lands an hour earlier on the East Coast, so nudge afternoon calls a touch later to catch New York after lunch.

Almost every failed international call is a formatting issue, not a network issue.
Tacking 011 onto a call from the US or Canada
you never do; Cayman is inside NANP, so it's just 1 345 like dialling another state.
Mentally filing it as a "foreign" call from within North America
for billing and dialling it behaves like a domestic long-distance number, not an international one.
Leaving off the 345 area code when calling in from anywhere off-island
Leaving off the 345 area code when calling in from anywhere off-island.
Expecting Cayman to spring forward with the US
it doesn't; it holds EST all year, so the gap shifts the moment your own clocks change.
Reading the prefix as the carrier
portability means that can be wrong.
Tips to reduce the cost of calling Cayman Islands
Lean on VoIP or a hosted +1 345 line instead of carrier long-distance billing.
Carry the call over the internet so it sidesteps mobile surcharges.
Hand Cayman contacts a 345 DID
they then reach you at island-local rates.
Dial inside the EST business day so the call lands first time.

Cayman Islands +1 — FAQ
Do I really not use 011 to call Cayman from the US?expand_more
Correct — Cayman is inside NANP under +1, so you dial 1 345 and the number, just like reaching another US state.
Why does the Cayman Islands share +1 with the United States?expand_more
Like much of the Caribbean, it's a NANP member; 345 is simply its assigned area code within that shared +1 plan.
How do callers outside North America reach Cayman?expand_more
They lead with their own exit code, then 1, then 345 — for example 00 1 345 from the UK.
How many digits is a Cayman number, and can I shorten it on-island?expand_more
It's a 7-digit subscriber number under 345; locally you can dial just those seven digits.
Which carriers sit behind the mobile prefixes?expand_more
Flow uses ranges like 23x/24x/43x/44x and Digicel uses 32x/33x/34x — though portability can override the prefix.
Why does Cayman's time seem to drift against New York in summer?expand_more
Cayman never adopts daylight saving, so when the US East Coast springs forward, the islands fall in line with US Central time for the season.
What's the currency, and roughly what's it worth?expand_more
The Cayman Islands dollar (KYD), pegged at about 1 KYD to 1.20 USD.
If I'm calling from outside NANP, what exit code does Cayman use?expand_more
Cayman's own NANP international prefix is 011 when its residents call beyond the plan; inbound, you use your country's exit code.
Can a Cayman number be ported between Flow and Digicel?expand_more
Yes — portability is supported, which is exactly why the prefix can't be trusted as a carrier ID.
Can MCM give me a 345 number without a Cayman office?expand_more
Yes — we provision genuine 345 NANP DIDs and route them to your team anywhere.
