# CONTACT_MATCH_CONFLICT

> Email belongs to another contact

| HTTP status | Retryable |
| - | - |
| `409` | No |

## What happened

The email you sent belongs to a different contact than the one with this phone number (or no contact has this phone number), so Blujay can't tell which contact to create or update. Nothing was changed.

## How to fix it

Leave out the email, or send the phone number of the contact that already has this email.

## Example response

An illustrative example. The `message` wording and the contents of `details` vary; branch on `error.code`.

```json theme={null}
{
  "status": "error",
  "error": {
    "code": "CONTACT_MATCH_CONFLICT",
    "message": "Email belongs to another contact",
    "type": "validation",
    "http_status": 409,
    "retryable": false,
    "doc_url": "https://docs.blujay.io/errors/contact-match-conflict",
    "details": []
  },
  "trace_id": "trc_8f2a1c0e4b7d",
  "timestamp": "2026-10-14T17:30:48.000Z"
}
```

## Still stuck?

Email [support@blujay.io](mailto:support@blujay.io) with the `trace_id` from the error response. See [Errors](/errors.md) for the response format.
