How to Add Custom Fields to WooCommerce Registration Form?

Based on the store’s specific business needs you can add custom fields to collect essential customer details from the registration form. Having additional details about customers enables store owners to send personalized promotions, discounts, or product recommendations based on the information collected during the registration process.

The code given below will add custom fields such as First name, Last name, Phone number, and country field to the WooCommerce registration page. Also, it will validate and save the field values that are entered and populate the values on the checkout page.

// Add extra fields to registration form
add_action('woocommerce_register_form_start', 'ts_extra_register_fields');

function ts_extra_register_fields()
    $countries_obj = new WC_Countries();
    $countries = $countries_obj->get_countries(); // Pass `false` to get all countries

    // First Name
    woocommerce_form_field('billing_first_name', array(
        'type' => 'text',
        'class' => array('form-row-first'),
        'label' => __('First name', 'woocommerce'),
        'required' => true,

    // Last Name
    woocommerce_form_field('billing_last_name', array(
        'type' => 'text',
        'class' => array('form-row-last'),
        'label' => __('Last name', 'woocommerce'),
        'required' => true,

    // Phone Number
    woocommerce_form_field('billing_phone', array(
        'type' => 'tel',
        'class' => array('form-row-wide'),
        'label' => __('Phone number', 'woocommerce'),
        'required' => true,

    woocommerce_form_field('billing_country', array(
    'type'         => 'select',
    'class'        => array('chzn-drop'),
    'label'        => __('Country'),
    'placeholder'  => __('Choose your country'),
    'options'      => $countries,
		'required' => true,


// Add JS code to My Account page footer
add_action('wp_footer', 'ts_AccountPageJS', 100);

function ts_AccountPageJS()
    if (is_account_page())
        echo '<script>jQuery(".myClass").select2();</script>';

// Validate the additional fields
add_filter('woocommerce_registration_errors', 'ts_validate_name_fields', 10, 3);

function ts_validate_name_fields($errors, $username, $email)
    if (isset($_POST['billing_first_name']) && empty($_POST['billing_first_name'])) {
        $errors->add('billing_first_name_error', __('<strong>Error</strong>: First name is required!', 'woocommerce'));
    if (isset($_POST['billing_last_name']) && empty($_POST['billing_last_name'])) {
        $errors->add('billing_last_name_error', __('<strong>Error</strong>: Last name is required!', 'woocommerce'));
	if (empty($_POST['billing_phone'])) {
        $errors->add('billing_phone_error', 'Phone is required!');
    return $errors;

// Save the additional fields
add_action('woocommerce_created_customer', 'ts_save_name_fields');

function ts_save_name_fields($customer_id)
    if (isset($_POST['billing_first_name'])) {
        update_user_meta($customer_id, 'billing_first_name', sanitize_text_field($_POST['billing_first_name']));
        update_user_meta($customer_id, 'first_name', sanitize_text_field($_POST['billing_first_name']));
    if (isset($_POST['billing_last_name'])) {
        update_user_meta($customer_id, 'billing_last_name', sanitize_text_field($_POST['billing_last_name']));
        update_user_meta($customer_id, 'last_name', sanitize_text_field($_POST['billing_last_name']));
