# Configuring Checkout Validation

The Checkout tab controls how Address Guard Pro works during WooCommerce checkout.

Go to:

**WooCommerce → Address Guard → Checkout**

From this tab, you can enable checkout validation, enable address autocomplete, choose whether shipping and billing addresses are checked, and decide what happens when an address fails validation.

## Checkout Integration

The **Checkout integration** section controls whether Address Guard Pro runs during checkout.

### Enable Checkout Validation

Enable this option to allow Address Guard Pro to validate addresses before the order is placed.

When enabled, the plugin can check the customer’s address using your selected validation provider and your local address rules.

## Checkout Compatibility

Address Guard Pro supports:

- WooCommerce Checkout Blocks
- Classic WooCommerce checkout shortcode

The Checkout tab shows the detected checkout type so you can confirm which checkout experience your store is using.

## Address Autocomplete

The **Address autocomplete** section controls address suggestions during checkout.

### Enable Address Autocomplete

Enable this option to show address suggestions while customers type.

Autocomplete can be applied to:

- Shipping address
- Billing address

### Minimum Characters Before Search

This controls how many characters the customer must type before address suggestions are requested.

Recommended value:

**3**

This prevents unnecessary provider requests and keeps the checkout experience smoother.

### Autocomplete Countries

Use this option to limit or bias autocomplete suggestions to selected countries.

If the customer has already selected a checkout country, that country is used as the main autocomplete context.

## Address Behavior

The **Address behavior** section controls which addresses are validated.

### Validate Shipping Address

Enable this if your store ships physical products.

This is the recommended setting for most stores.

### Validate Billing Address

Enable this if your store also needs to check billing addresses.

This can be useful for stores that need accurate billing details, but it may not be necessary for every store.

### Allow Customer to Continue with Unverified Address

If enabled, customers may continue when validation cannot fully verify the address.

Use this when you want to avoid blocking legitimate customers because of provider uncertainty.

## Checkout Action

The **Checkout action** controls what happens when an address fails validation.

### Warn Customer

Shows a warning but allows the customer to continue.

Recommended when first enabling the plugin.

### Block Checkout

Prevents the customer from placing the order until the address is corrected or verified.

Recommended only after you have tested your rules and provider behavior.

## Recommended Setup

For most stores:

- Enable checkout validation: **On**
- Enable address autocomplete: **On**
- Apply autocomplete to shipping address: **On**
- Validate shipping address: **On**
- Validate billing address: **Off**
- Checkout action: **Warn customer**

Once you are confident the plugin is working correctly, you can enable stricter blocking rules.
