Step 1: Create a plugin for the \Magento\Checkout\Block\Checkout\LayoutProcessor::process method. because billing and shipping address forms are generated dynamically.

So we need create a plugin on process method LayoutProcessor class. First we have to make an entry in di.xml on this path app/code/CompanyName/Module/etc/frontend/di.xml

<config xmlns:xsi="" xsi:noNamespaceSchemaLocation="urn:magento:framework:ObjectManager/etc/config.xsd"> <type name="Magento\Checkout\Block\Checkout\LayoutProcessor"> <plugin name="add_custom_field" type="VendorName\Module\Model\Plugin\Checkout\LayoutProcessor" sortOrder="100"/> </type> </config>

Step 2: Create plugin class on this Directory. app\code\VendorName\Module\Model\Plugin\Checkout

Here we used After listener Plugin.

<?php namespace VendorName\Module\Model\Plugin\Checkout; class LayoutProcessor { /** * @param \Magento\Checkout\Block\Checkout\LayoutProcessor $subject * @param array $jsLayout * @return array */ public function afterProcess( \Magento\Checkout\Block\Checkout\LayoutProcessor $subject, array $jsLayout ) { $jsLayout['components']['checkout']['children']['steps']['children']['shipping-step']['children'] ['shippingAddress']['children']['shipping-address-fieldset']['children']['custom_field'] = [ 'component' => 'Magento_Ui/js/form/element/abstract', 'config' => [ 'customScope' => 'shippingAddress.custom_attributes', 'template' => 'ui/form/field', 'elementTmpl' => 'ui/form/element/input', 'options' => [], 'id' => 'add-custom-field' ], 'dataScope' => 'shippingAddress.custom_attributes.custom_field', 'label' => 'Custom Field', 'provider' => 'checkoutProvider', 'visible' => true, 'validation' => [], 'sortOrder' => 250, 'id' => 'add-custom-field' ]; return $jsLayout; } }
