# New v3 API endpoints for adding phone for risk verification

We have introduced a set of API endpoints for adding a phone for a user. You can also check whether a phone number has been added for the user. BILL requires users to have a linked phone number for initiating risk verification for an organization.

| Operation                                                                                                    | API endpoint                        |
