body: <p>How can I display Phone number in new account registration email?</p>
  
  <p>I have add Phone number field like:</p>
  
  <pre><code>&lt;p class="form-row form-row-wide"&gt; &lt;label for="reg_billing_phone"&gt;Phone &lt;span class="required"&gt;*&lt;/span&gt;&lt;/label&gt; &lt;input type="text" class="input-text" name="billing_phone" id="reg_billing_phone" value=""&gt;&lt;/p&gt;
  </code></pre>
  
  <p>The Customer new Account email template code is <em>(Where I want to display the number phone)</em>:</p>
  
  <pre><code>&lt;?php
  /**
   * Customer new account email
   *
   * This template can be overridden by copying it to yourtheme/woocommerce/emails/customer-new-account.php.
   *
   * HOWEVER, on occasion WooCommerce will need to update template files and you
   * (the theme developer) will need to copy the new files to your theme to
   * maintain compatibility. We try to do this as little as possible, but it does
   * happen. When this occurs the version of the template file will be bumped and
   * the readme will list any important changes.
   *
   * @see         https://docs.woocommerce.com/document/template-structure/
   * @author      WooThemes
   * @package     WooCommerce/Templates/Emails
   * @version     1.6.4
