# Import domains

The **Import domains** feature lets you add more than five domain restrictions to your reader self-registration settings in a single operation using a CSV file. You can import up to 500 domains at once and apply a single restriction type (Allow or Block) to all imported domains.

---

## When to import domains

- You need to add more than 5 domain restrictions at once.
- You have a prepared list of domains ready in a spreadsheet and want to avoid entering them one by one.

---

## Before you begin

- You must have the **Admin** or **Owner** portal role, or a custom role with **Manage user** permission.
- The **Enable reader self-registration** toggle must be turned on.
- Prepare a CSV file using the Document360 template (downloaded during the import flow). Do not modify the column headers.

## How to import multiple domains

1. Navigate to **Settings** () > **Users and security** in the left navigation bar of the knowledge base portal.
2. In the left navigation pane, navigate to **Readers & groups** > **Readers**.
3. Click the dropdown next to **Add domain** and select **Import domains**.

The **Import domains** panel appears.
4. Click **Download template** to get the sample CSV template.
5. Upload the CSV file using one of the following methods:

a. **Upload from my device**: Select the CSV file from your local file explorer.

b. **Drag and drop**: Drag and drop the CSV file into the designated area.

> [!NOTE]
> **NOTE** You can import up to 500 domains at once.

1. A validation summary displays:
  - **Valid Domains**: Number of valid entries.
  - **Invalid Domains**: Number of invalid entries. Click the **Download** (

) icon to view details of the invalid entries.
2. Select the restriction type: **Block** or **Allow**.
3. Click **Import**.

## Considerations

| Item | Detail |
| --- | --- |
| Maximum domains per import | 500 |
| File format | CSV only. Use the Document360 template — custom formats are not supported. |
| Restriction type | A single restriction type (Block or Allow) applies to all domains in the import batch. Split into separate imports if you need different restriction types. |
| Reader group mapping | Reader group mapping is not available during bulk import. Add domain-specific group mappings individually after import using [Edit a domain restriction](/help/docs/edit-or-delete-domain-restriction). |

## Best practices

- Always use the downloaded CSV template. Uploading a file with different column headers or formatting will cause validation errors.
- Review the validation summary before confirming the import. Download the invalid entries list, fix the errors, and re-upload if needed.
- If you need to import domains with different restriction types, split them into separate import operations — one for Allow domains and one for Block domains.
