# List a customer's organizations

> Lists the business organizations a customer belongs to, identified by their `customerId` (the JWT `sub`). This is the reverse of [List organization members](/api-reference/organizations/list-organization-members): that returns the members of one org, this returns the orgs one member is in.

Scoped to your own child organizations, so it never reveals another partner's orgs. A `customerId` outside your namespace (or one that isn't a member of any of your orgs) returns an empty array.
