> Choose and automate authority-to-leave or signature-required delivery options for supported courier services.

Choose whether a supported courier can leave a parcel without a signature or must collect a signature on delivery.

## Choose a delivery option

- **Authority to leave (ATL)** allows a courier to leave the parcel in a safe place when the recipient is unavailable.
- **Signature required** asks the courier to collect a signature when the parcel is delivered.

The exact behavior, availability, and price of each option depends on the courier and service. Confirm the requirements with your courier before applying an option to your shipments.

## Set a default for a courier

Some courier integrations let you set a default delivery option in their advanced settings:

1. Go to **Settings > Couriers**.
2. Open the settings for your courier.
3. Select **Advanced**.
4. Enable the supported authority-to-leave, safe-drop, or signature-required option.
5. Select **Save**.

The available setting and its name vary by courier. Review the courier's setup guide if the option does not appear.

## Apply a delivery option with a rule

Use a rule when the option should apply only to matching orders, such as high-value orders:

1. Go to **Settings > Rules**.
2. Select **Add a new rule**.
3. Add the conditions that identify the orders.
4. Add **Set Authority To Leave** or **Set Signature Required** as the action, then set it to `True`.
5. Select **Save**.

To apply the rule to orders already in **New**, select **Run rules now**. Check a matching order before printing to confirm the expected delivery option was applied.

Delivery options can affect the quoted rate and whether the courier accepts the shipment. Confirm the final service and price before printing the label.
