If a customer’s phone number is not required for orders or support, removing the phone number field is a great way to simplify the checkout form.

You can either do this with code or a plugin, depending on what you are more comfortable with.

Remove with a Plugin

The free plugin Checkout Field Editor (Checkout Manager) for WooCommerce allows you to edit, remove or add fields to the checkout form.

1. Install the plugin
2. Go to the settings page for the plugin
3. Select the “billing_phone” field and click “Remove”
4. Click “Save Changes”

Remove with Code

Here’s the code snippet to remove the billing phone number field from checkout:

/**
 * Remove the phone number field from checkout.
 */
function devpress_remove_checkout_phone_field( $fields ) {
	unset( $fields['billing']['billing_phone'] );
	return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'devpress_remove_checkout_phone_field' );
