# KYB Testing

> Test data for simulating KYB verification outcomes in the staging environment

Use the test values below to simulate business verification (KYB) outcomes in the staging environment. These values only work in staging — they will not produce deterministic results in production.

## EIN test values

Pass the following values in the `tax_id` field when creating or verifying a business to trigger a specific KYB decision.

| `tax_id`     | Result   |
| ------------ | -------- |
| `11-1111111` | Approved |
| `22-2222222` | Declined |
| `33-3333333` | Declined |

<Note>
  Any `tax_id` value other than those listed above may return non-deterministic results in staging. Always use the designated test values when building and testing your KYB integration.
</Note>

## Example request

```json theme={null}
{
  "legal_business_name": "Test Business LLC",
  "tax_id": "11-1111111",
  "business_type": "llc"
}
```

## Testing decline handling

Use `22-2222222` or `33-3333333` to verify that your integration correctly handles a declined KYB decision, including:

* Surfacing the declined status to your operations team
* Preventing account provisioning for unverified businesses
* Handling any resubmission or manual review flow your program supports
