# Export and Import Emergency Numbers

Cloud Voice lets you move emergency numbers in and out of the phone system as a CSV file (a comma-separated values file that opens in any spreadsheet program). Exporting produces a ready-made template you can edit offline, and importing writes those entries back to the system. This is the fastest way to review, bulk-edit, or migrate your emergency dial rules instead of adding numbers one at a time in the portal.

:::note
Emergency numbers define which dialed digits the phone system treats as emergency (E911, enhanced 911) calls, so it knows to route them to emergency services. Keeping this list correct is what allows a user to reach help when they dial for it.

## Export emergency numbers

Export sends every emergency number to a single CSV file, which you can then add to, trim, or adjust as needed.

1. Sign in to the PBX (private branch exchange, your business phone system) web portal and open **Call Control > Emergency Number**.
2. Click **Export**.

   The CSV downloads to your computer. For the meaning of each column and how to fill it in, see [Emergency Number Parameters](/pbx/administrator-guide/import-and-export-parameters-emergency-numbers/).

## Import emergency numbers

:::tip
Export your existing emergency numbers first and edit that file. Starting from the exported CSV gives you a correctly formatted template and saves you from building one by hand.
:::

Before you import, make sure your file meets these requirements:

- **Format**: UTF-8 CSV
- **Size**: under 50 MB
- **File name**: fewer than 127 characters
- **Contents**: every value must satisfy the parameter rules described in [Emergency Number Parameters](/pbx/administrator-guide/import-and-export-parameters-emergency-numbers/)

:::danger
These entries control how the phone system recognizes and routes emergency (E911) calls. A wrong, malformed, or missing row can cause an emergency call to fail or route incorrectly. Check every row against [Emergency Number Parameters](/pbx/administrator-guide/import-and-export-parameters-emergency-numbers/) before you import, and place a test call to confirm emergency dialing still works afterward.
:::

To import the file:

1. Sign in to the PBX web portal and open **Call Control > Emergency Number**.
2. Click **Import**.
3. In the window that opens, click **Browse** and choose your CSV file.
4. Click **Import**.

   The entries from the file appear in the **Emergency Number** list.
