The Prove integration verifies customer identities using phone-based signals, returning a phone trust score, auto-filling user data, and verifying submitted details. For setup steps, see [Get started](/connectors/kyc-kyb/prove/get-started).

## Supported operations

The Prove connector supports the following operations.

### Phone number verification

* Retrieve a trust score for a submitted phone number

### User data auto-fill

* Retrieval of user personal information (first name, last name, date of birth, SSN number, address, and email address).

### User data verification

* Download all documents generated during the IDV process (for example, IDV process reports, face scan video, document scan images).

## Events

This connector is synchronous and doesn't publish or consume events.

## Error mapping

The following table maps each Prove error code to its Grand Central counterpart:

| Prove code | Grand Central code |
| :--------- | :----------------- |
| `1`        | `GC027`            |
| `2`        | `GC024`            |
| `3`        | `GC061`            |
| `408`      | `GC061`            |
| `1000`     | `GC025`            |
| `1001`     | `GC106`            |
| `1002`     | `GC025`            |
| `1003`     | `GC107`            |
| `1005`     | `GC107`            |
| `1006`     | `GC108`            |
| `1007`     | `GC109`            |
| `1010`     | `GC107`            |
| `1012`     | `GC107`            |
| `1038`     | `GC110`            |
| `1039`     | `GC060`            |
| `1102`     | `GC065`            |
| `1103`     | `GC065`            |
