# Audit Trail

> Review the immutable chronological record of every action performed on BCB mail, and export it as CSV for compliance evidence and BACEN audit reviews.

The **Audit Trail** is a chronological, immutable record of every action performed on Banco Central do Brasil (BCB) mail in BC Correios. It provides traceability and regulatory compliance evidence, and it can be exported as CSV.

## Accessing the Audit Trail

***

Open **Reporter** > **BC Correios** > **Trilha de Auditoria** from the left-side menu. The screen is headed **Audit Trail**.

<Note>
  The Audit Trail requires the `audit:get` permission, which also covers CSV export. Without it, you see a "not authorized" page. Audit events are retained for 5 years.
</Note>

## Reading the audit table

Each row records one event:

| Column        | Description                                                          |
| :------------ | :------------------------------------------------------------------- |
| **Action**    | The type of event (see the list below).                              |
| **User**      | The user who performed the action, or `System` for automated events. |
| **Mail**      | The related mail, when applicable. Click to open its detail view.    |
| **Date/Time** | When the event occurred.                                             |

## Filtering events

***

Use the filter bar to focus the trail:

* **From date** and **To date** — restrict to a date range. The default range is the last 7 days.
* **All actions** — the default; pick one action type to show only that one.
* **Items per page** — control how many rows are shown.

## Exporting to CSV

***

Click **Export CSV** to download the currently filtered events. The export honors the active action and date-range filters, so you can produce a targeted compliance report.

<Tip>
  Export after setting a date range and action filter to generate evidence for a specific event type or reporting period.
