Claude Duet outside the US

What the Duet pages say

Three official pages describe this research preview as US-only:

• The product page says Duet is available on Pro and Max plans in the US. Its FAQ says the waitlist is for Claude Pro and Max subscribers in the US.
• The support article says you need a Claude account in the US, and that Duet is available in the US only during the research preview.
• The introducing article, published 2026-10-21, says the preview starts with US Pro and Max subscribers.

If your Claude account is not in the US, the requirement in the support article is not met. Those three pages do not give a date for offering the preview in other countries.

Team and Enterprise are a separate limit. The support article says those plans are not included yet, and that Anthropic plans to bring Duet to them later. That sentence is about plans. It does not say the preview is opening in more countries.

How the waitlist itself works, for accounts that do meet the US requirement, is on the access page.

A Claude country list is not a Duet list

Anthropic's supported regions page lists where its products and services are offered, including the Claude apps. The help article Where can I access Claude? is a country list for accessing Claude. A country on those lists is not a statement that Claude Duet is offered there.

Duet's own pages, linked above, are the ones that say the preview is US-only. This page only restates that published status.
