The Cayman Islands country code is +1 — the SAME North American Numbering Plan +1 as the US + Canada, reached through the nationwide area code 345. A British Overseas Territory + a world-leading offshore financial centre, with Grand Cayman, Cayman Brac + Little Cayman. Cayman bank verifications all expect +1 345.
The Cayman Islands share the +1 country code of the North American Numbering Plan with the US + Canada. The territory is reached with +1 followed by its area code — 345 — that blankets all three islands.
The Cayman Islands do NOT have a unique country code — the territory is part of the North American Numbering Plan (NANP) and uses <b>+1</b>, the same code as the US + Canada. A Cayman number is <b>+1</b> followed by the area code <b>345</b>, then a 7-digit local number: <code>+1 345 123 4567</code> = 10 digits after +1. From North America you reach Cayman almost like a domestic call (no 011), but it is a separate territory billed at international rates.
The Cayman Islands are a <b>British Overseas Territory</b> in the Caribbean, with George Town on Grand Cayman as the capital. Two carriers serve the market: <b>Flow Cayman</b> (Cable & Wireless / Liberty Latin America) + <b>Digicel Cayman</b>. Both issue mobile numbers across the 345 area code. ITU zone 1.
The Cayman Islands use a single area code — <b>345</b> — as a <b>nationwide overlay</b> that covers the entire territory: Grand Cayman, Cayman Brac + Little Cayman. The code does NOT map to a specific island or district; every Cayman number is +1 345 followed by 7 digits. Ten-digit dialing (area code + number) is standard for every call.
The Cayman Islands are a world-leading offshore financial centre. They are one of the largest domiciles for hedge funds on earth + a major international banking hub, with no direct taxation. The territory is three islands — Grand Cayman, Cayman Brac + Little Cayman — and tourism is the other economic pillar: Seven Mile Beach, Stingray City + world-class wall diving draw visitors year-round, while George Town is both the capital + a busy cruise port. Cayman banks verify with +1 345 mobile OTPs.
