Claim and migrate accounts on your domain (original) (raw)

Domain claiming lets Enterprise admins discover, claim, and migrate existing personal Claude accounts (Free, Pro, and Max) on a verified company domain into their Enterprise workspace. This gives your organization a clean path to consolidate accounts on day one of an Enterprise deployment, and allows people using Claude on personal accounts to keep their work. Domain claiming is available for Enterprise plans, whether purchased directly through Anthropic or through the AWS Marketplace, and works the same in both cases.

Team plans can verify a domain and block new personal accounts from being created, but admins can't claim or migrate existing accounts. People on a Team plan can still migrate their own personal accounts voluntarily—see Move your personal Claude account to a Team or Enterprise organization.

Prerequisites

Before you can enable domain claiming, your organization must have all of the following in place:

These prerequisites exist to prevent people from being locked out of Claude during the migration process. If SSO is enforced and provisioning is active, everyone on your domain will have a path to sign in after their accounts are migrated.

How domain claiming works

Review accounts on your domain

After verifying your domain, you can view all existing personal accounts (Free, Pro, and Max) on that domain that aren’t already in your organization. For each account, you’ll see the email address, plan type, account creation date, and last active date. You can also export this list as a CSV.

Use this view to understand the scope of migration before initiating a claim. Check which accounts are in your identity provider (IdP) and which aren’t—people not in the IdP won’t be able to sign in after migration unless you add them.

Enable domain capture

Navigate to Organization settings > Organization and access, scroll down to Security and toggle Migrate accounts using your domain on to enable domain capture. This is an organization-level setting that enforces a policy: no non-Enterprise accounts can exist on your verified domain.

Initiate the claim

When you enable domain capture, you’ll walk through a flow that shows you the migration impact:

Once confirmed, all affected accounts receive notification immediately—both by email and through an in-product banner. The migration window is 30 days from the date you initiate the claim.

The 30-day migration window

The migration deadline is a single org-wide date, not a rolling per-user timer. All affected accounts share the same deadline.

During this window, each person on the domain can sign in and choose how to migrate:

What happens at the deadline

New accounts created on the domain after domain capture is enabled go directly through SSO and your Enterprise workspace—no personal account is created.

What’s not supported

SSO and provisioning sequencing

Domain claiming integrates with your existing SSO and provisioning setup:

Frequently asked questions

What happens if my organization doesn’t have enough seats available for migrated users?

If you purchased your Enterprise plan directly through Anthropic, you'll see an error message in organization settings prompting you to buy more seats.

If you purchased your Enterprise plan through the AWS Marketplace, migrated users will see a message asking them to contact their admin when they try to log in after the migration.
