# Firmographic Enrichment Attributes

Tamr matches each of your company records against our firmographic corpus and returns enrichment attributes based on the company information in the record:

* Company name and alternative name
* Address attributes
* Phone
* Website
* Registration number

When a matching reference record is found, Tamr returns a number of enrichment attributes: 

* **Match explainability attributes:** Provide the organization id of the matching reference record as well as confidence level and the attributes on which the records matched.
* **Hierarchy attributes:** Provide organization IDs for the parent, domestic ultimate parent, and global ultimate parent (if available)
* **Enrichment source provider attributes:** Tamr returns a specific set of attributes per selected enrichment source.

# Match Explainability Attributes 

Tamr returns these `top_firmographic_match_result` attributes for each record for which it identifies a match.

<Table>
  <thead>
    <tr>
      <th>
        Firmographic Match Result Attribute
      </th>

      <th>
        Description
      </th>
    </tr>
  </thead>

  <tbody>
    <tr>
      <td>
        `tamr_erich_id`
      </td>

      <td>
        The organization id (`org_id` ) of the matching reference record in Tamr's firmographic corpus.
      </td>
    </tr>

    <tr>
      <td>
        `match_confidence`
      </td>

      <td>
        The level of confidence with which Tamr matched this record:

        - Very high
        - High
        - Medium
        - Low
      </td>
    </tr>

    <tr>
      <td>
        `match_drivers`
      </td>

      <td>
        The attributes on which the record matched or partially matched to the organization in Tamr's firmographic corpus (company name, address attributes, phone, registration number, website, and so on).
      </td>
    </tr>
  </tbody>
</Table>

These attributes are available in the **External Enrichment** section of the 360 page, as shown below.  You can hover over the confidence level to view the match drivers for the enrichment results. &#x20;
