I want to add US phone number format without adding validation on form. Eg: if user enters 805839483 in form, It should display (805) 583-9483 on shipping addresses.

Can anybody help me?

You can add following changes for US phone number format on Checkout Page.

  1. First, create checkout_index_index.xml file inside app\code\Vendor\Extension\view\frontend\layout\ folder and add this code:

     <page xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:noNamespaceSchemaLocation="urn:magento:framework:View/Layout/etc/page_configuration.xsd">
             <referenceContainer name="after.body.start">
                 <block class="Magento\Framework\View\Element\Template" before="-" template="Vendor_Extension::inputformat.phtml"/>

2.Then Add inputformat.phtml file inside app\code\Vendor\Extension\view\frontend\templates\ folder and add this code:

<script src="https://s3-us-west-2.amazonaws.com/s.cdpn.io/3/jquery.inputmask.bundle.js"/></script>
    ], function($) {
                $('input[name$="telephone"]').inputmask({"mask": "+1(999) 999 99 99"});
            }, 6000);

Checkout Page Address

  • Phone Number validation as per US Format on Edit Billing address

Phone Number Validation

  • Phone Number validation as per US Format on the Shipping address Shipping Address

You can accomplish this by using the Input Mask jQuery extension.

$('#phoneNumber').inputmask("(999) 999-9999");

use this js for that:- jquery.inputmask.bundle.js
