# Data Model

> Zenoo accepts and returns verification data at three tiers: Minimum, Standard, and Full.

Zenoo accepts and returns verification data at three tiers: **Minimum**, **Standard**, and **Full**. The more data you provide, the richer the results, the faster the processing, and the fewer false positives.

## Three-Tier Data Model

Every verification request accepts a flexible set of fields. Not all fields are required. Zenoo categorizes input into three tiers based on how much data you supply:

| Tier         | What You Provide                                                       | What You Get                                               |
| ------------ | ---------------------------------------------------------------------- | ---------------------------------------------------------- |
| **Minimum**  | Core identifiers only                                                  | Basic verification and screening                           |
| **Standard** | Identifiers + context (addresses, dates, related persons)              | Full verification with entity correlation and risk scoring |
| **Full**     | Everything available, including external references and financial data | Maximum accuracy, idempotency, enriched risk assessment    |

<Tip>
  Providing Standard tier or above is recommended for production deployments.

## Company Verification Tiers

| Tier         | Required Fields                                                         | Optional Additions                       |
| ------------ | ----------------------------------------------------------------------- | ---------------------------------------- |
| **Minimum**  | `company_name`, `registration_number`, `country`                        | Registry check + company screening       |
| **Standard** | + `directors[]`, `ubos[]`, `address`, `industry`                        | Individual screening, entity correlation |
| **Full**     | + `external_reference`, `annual_revenue`, `sic_codes`, `employee_count` | Idempotency, enriched risk scoring       |

## Person Verification Tiers

| Tier         | Required Fields                                                       | Optional Additions                                      |
| ------------ | --------------------------------------------------------------------- | ------------------------------------------------------- |
| **Minimum**  | `first_name`, `last_name`, `country`                                  | Basic screening                                         |
| **Standard** | + `date_of_birth`, `email`, `phone`, `address`, `city`, `postal_code` | Identity verification, phone/email checks               |
| **Full**     | + `nationality`, `document_type`, `external_reference`                | Idempotency, document preference, enriched risk scoring |
