# EU Entity (Business) Onboarding

## EU Entity (Business) Onboarding

`POST /participants/entity/new` accepts both US and EU businesses through a single endpoint. Set `jurisdiction_code` to route a payload to EU processing. The request body is a set of titled variants keyed by jurisdiction and entity type; **EU businesses are onboarded under a reliance model**, so they map to the entity-type-specific "**EU – … – Reliance**" variants — e.g. `EU - Corporation - Reliance`, `EU - LLC - Reliance`, `EU - Trust / Estate - Reliance` — each with its own required-field set. There is no non-reliance EU variant. See [Create Entity](https://docs.zerohash.com/reference/post_participants-entity-new) for the full schema and example payloads.

### What's different for EU entities

In addition to the base business details required for every entity (legal name, entity type, registered address, contact details, tax id, control persons, beneficial owners), EU entities must also provide:

| Field                                                 | Description                                                                                                                                    |
| ----------------------------------------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------- |
| `chamber_of_commerce_number`                          | Chamber of commerce registration number                                                                                                        |
| `id_number` + `id_number_type`                        | LEI (`id_number_type: legal_entity_identifier`)                                                                                                |
| `board_members`                                       | At least one board member (distinct from control persons/beneficial owners)                                                                    |
| `activity_locations`                                  | ISO 3166-1 alpha-2 country code(s) of business activity                                                                                        |
| `expected_annual_volume`                              | Expected annual transaction volume tier                                                                                                        |
| `entity_source_of_funds`                              | Primary source of funds (`entity_source_of_funds_description` required if `other`)                                                             |
| `risk_rating`                                         | Reliance: the platform's own risk rating for the entity                                                                                        |
| `sanction_screening` + `sanction_screening_timestamp` | Reliance: the platform's attestation that it screened the party, with the timestamp of that screening. **Also required on each board member.** |

Optional (not required by the schema):

| Field                                                                                            | Description                                                                                 |

| `is_complex_structure`, `declaration_no_effective_control`, `declaration_no_foreseeable_changes` | Ownership-structure attestations                                                            |
| `entity_sub_type`                                                                                | Further classifies trust entities (`trust_llc`, `trust_sole_proprietorship`, `trust_other`) |

Every EU entity requires at minimum one board member, one control person, and one beneficial owner. Board members can only be submitted at entity **creation** — see [Entity User Management](https://docs.zerohash.com/reference/entity-user-managment) for how to read or update them afterward.

### Required documents

EU entities must submit the following documents via [Submit Entity Documents](https://docs.zerohash.com/reference/post_participants-entity-documents):

* `lei_certificate`
* `excerpt_of_the_chamber_of_commerce`
* `annual_accounts`
* `power_of_authorization` (power of attorney or board resolution authorizing the submitter)
* `legal_opinion` — additionally required if the entity was created with `is_complex_structure: true`
