# BusinessOwnerInput

> Business owner information for registration.

**Input object**

Business owner information for registration.

At least one of `emailAddress` or `phoneNumber` must be provided.
Exactly one owner in the roster must be the control person (`isControlPerson: true`).
Exactly one owner must match the bearer token user's email address (the applicant).

Full KYC fields (`dob`, `address`) are required for owners who are not the applicant, not invited,
and either a beneficial owner (>= 25% ownership) or the control person.

* SSN verification: optionally provide `lastFourSsnDigits` (exactly 4 digits) with `dob` and `address`.
* Document verification: provide `dob` and `address` without `lastFourSsnDigits`.
* `isUsPerson` is optional and does not determine which verification path is used.

Invited owners (`isInvited: true`) and non-beneficial owners (\< 25%, not control person) only require base contact fields.
