Local 345 numbers, issued in Cayman

Get a Cayman phone number — without the landline.

A local 345 number for your business, live in a couple of days. No copper line, no engineer visit — it rings your desk phone, your mobile and your computer at once. Already have a number? Bring it with you.

First, the short answers

What is Cayman's area code?
+1 345. Numbers are written +1 345 xxx xxxx.
Got a missed call from a 345 number?
It just means the call came from the Cayman Islands — it says nothing about who was calling. If you weren't expecting it, treat it like any unknown number and don't share personal or banking details. Nobody can legitimately look up who owns a number for you.
Want a 345 number of your own?
That's what we do — the rest of this page is about that.
What a 345 number can be

One number, or one for each job.

A Cayman number on a cloud phone system isn't tied to a desk, a building or a copper line. That makes it far more useful than the landline it replaces.

  • A business 345 number

    A local Cayman number customers recognise — on your website, your van and your invoices.

  • A second line on one phone

    Work and personal on the same mobile. Business calls arrive marked; your own number stays private.

  • Numbers for teams or jobs

    A separate number for bookings, accounts or a manager — each routed its own way.

  • A number that replaces a landline

    A virtual number with no copper line: no engineer visit, and it moves when your office does.

Switching provider

Keep the number your customers already know.

Changing provider doesn't mean changing number. If you already have a Cayman business number, we port it across: we deal with your current provider, agree a switch-over time with you, and plan it so you don't miss calls on the day. Everything printed, listed or saved in a customer's phone carries on working.

  • We handle the paperwork with your existing provider
  • You pick the switch-over window, and we work to it
  • Your number keeps ringing throughout the move
  • Add extensions, a caller menu and Voice AI once it lands

Common questions

Cayman phone numbers — answered.

What is the Cayman Islands phone number area code?

The Cayman Islands country/area code is +1 345. A Cayman number is written +1 345 xxx xxxx and is dialled from the US, Canada and most Caribbean countries as a normal long-distance number rather than an international one.

How do I get a Cayman phone number?

For a business, we issue a local 345 number on a cloud phone system — usually within a couple of working days, with no copper line and no engineer visit. It rings your desk phone, your mobile and your computer at once, and you can add more numbers whenever you need them.

Can I get a Cayman number without a landline?

Yes. A virtual 345 number needs no physical line at all — it lives in the cloud and rings whichever devices you choose. It does everything a business landline used to do, and it keeps working if the office loses power or internet, because calls can fall back to mobiles.

Can I keep my existing 345 number?

Yes. If you already have a Cayman business number, bring it with you — we deal with your current provider and plan the switch so you do not miss calls on the day. Your customers carry on dialling the number they already know.

Can I have a second number on the same phone?

Yes. You can run a business 345 number alongside your personal one on the same mobile, so work calls arrive clearly marked and your personal number stays private. You can also have separate numbers for bookings, accounts or a particular manager.

Who called me from a 345 number?

A 345 number is simply a Cayman Islands number — it does not tell you who is calling. If you were not expecting a call from Cayman, treat it the way you would any unknown number and do not share personal or banking details. We cannot look up the owner of a number, and neither can any legitimate provider.

How much does a Cayman business number cost?

A business number comes as part of our phone system at CI$45 per user per month, which includes extensions, an auto-attendant, business-hours routing, voicemail to email and the Voice AI receptionist. Extra numbers and lines that are not tied to a person cost less — tell us what you need and we will price it.
