try this, Update LayoutProcessor.php


namespace Ketan\Module\Plugin\Block;

class LayoutProcessor
    protected $checkoutSession;

    public function __construct(
        \Magento\Checkout\Model\Session $checkoutSession
    ) {
        $this->checkoutSession = $checkoutSession;

     * @param \Magento\Checkout\Block\Checkout\LayoutProcessor $subject
     * @param array $jsLayout
     * @return array
    public function afterProcess(
        \Magento\Checkout\Block\Checkout\LayoutProcessor $subject,
        array $jsLayout
    ) {
        $postcode = 369856;
        $quote = $this->checkoutSession->getQuote();
        $shippingAddress = $quote->getShippingAddress();

        // Update the shipping address with the custom zip code

        /*================Start For Shipping Address ===========*/

            ['shippingAddress']['children']['shipping-address-fieldset'])) {

            ['children']['shippingAddress']['children']['shipping-address-fieldset']['children']['postcode']['value'] = $postcode;


        /*================End For Shipping Address ===========*/

        /*================Start For Billing Address ===========*/
            ['payment']['children']['payments-list'])) {
            $paymentsList = $jsLayout['components']['checkout']['children']['steps']['children']['billing-step']['children']

            foreach ($paymentsList as $paymentCode => $payment) {
                if(strpos($paymentCode, '-form') === false) {
                ['payment']['children']['payments-list']['children'][$paymentCode]['children']['form-fields']['children']['postcode']['value'] = $postcode;

            ['payment']['children']['afterMethods']['children']['billing-address-form']['children']['form-fields']['children']['postcode']['value'] = $postcode;


        /*================End For Billing Address ===========*/
        return $jsLayout;

  • Checkout page loads with zip code, but I see only one shipping method - imgur.com/a/suiKa4u, but if I change zip code field manually - shipping methods refresh and a have two items

  • No, checkout module used from Magento. The initial task is to hide the free shipping method and activated another shipping method instead. I'm trying to do this by specifying the default zip code and then influencing the choice of delivery via JS. Maybe there is an easier way to hide the free shipping method when loading the default shipping page and choose another one, knowing its carrierCode and methodCode?
