I'm looking for code to convert guest checkout customer to regular customer on successful order placement.

\Magento\Sales\Api\OrderCustomerManagementInterface $orderCustomerService in this class I have found one method called create that is accepting order id and converting to a customer. But I guess it is not working.

Anyone know the solution?


Finally, I got the solution. By defining event checkout_onepage_controller_success_action and write a below code in observer we can convert the guest user to customer

        $orderId = $orderIds[0];
        $order = $this->_orderFactory->create()->load($orderId);

        /*Convert guest to customer*/
        if ($order->getEntityId() && $this->accountManagement->isEmailAvailable($order->getEmailAddress())) {


Use below event

<event name="checkout_onepage_controller_success_action">
        <observer name="guestregistration" instance="Vendor\Module\Observer\ConvertGuest" />

In Observer file ConvertGuest.php

namespace Vendor\Module\Observer;

class ConvertGuest implements \Magento\Framework\Event\ObserverInterface

    public function __construct(
        \Magento\Store\Model\StoreManagerInterface $storeManager,
        \Magento\Sales\Api\OrderCustomerManagementInterface $orderCustomerService,
        \Magento\Sales\Model\OrderFactory $orderFactory,
        \Magento\Sales\Api\OrderRepositoryInterface $orderRepository,
        \Magento\Customer\Model\CustomerFactory $customer
    ) {
        $this->_storeManager = $storeManager;
        $this->orderCustomerService = $orderCustomerService;
        $this->_orderFactory = $orderFactory;
        $this->orderRepository = $orderRepository;
        $this->_customer = $customer;

    public function execute(\Magento\Framework\Event\Observer $observer)
        $orderIds = $observer->getEvent()->getOrderIds();

        $orderId = $orderIds[0];
        $order = $this->_orderFactory->create()->load($orderId);

        $customer= $this->_customer->create();

        //Convert guest into customer
        if ($order->getId() && !$customer->getId()) {
        } else {
            //if customer Registered and checkout as guest

Note :: if new customer not shown in customer-grid run indexer:reindex and check

    works perfectly but there is an extra comma to remove in you constructor after \Magento\Customer\Model\CustomerFactory $customer(,) Jul 26 '20 at 3:37
  • any particular reason to use the OrderFactory? because load($orderId) is deprecated and there is already the OrderRepositoryInterface with get($orderId) to load the order. Jul 26 '20 at 17:01

Below are the two extension links which does the same functionality - Second one is available as free package :

Module Pay: https://www.commerceextensions.com/magento-convert-guest-checkout-customers-to-registered-customers-magento-2.html

Free Module on GitHub: https://github.com/magepal/magento2-guest-to-customer

  • @LucasD.A.W. What issue are you having with the MagePal extension? Apr 15 '20 at 21:26
  • same on 2.1.9, blank page on Stores -> Configuration. composer require magepal/magento2-guest-to-customer | php bin/magento setup:upgrade (dev mode) Jul 26 '20 at 16:36

You can use extension :

Also, you can use code

$collection     = $this->filter->getCollection($this->collectionFactory->create());
        $collectionSize = $collection->getSize();
        $count          = 0;
        /** @var $order \Magento\Sales\Model\Order */

        foreach ($collection as $order) {
            $websiteId  = $order->getStore()->getWebsiteId();
            $storeId    = $order->getStore()->getId();

            $customerData = $this->objectCopyService->copyFieldsetToTarget(

            $addresses = $order->getAddresses();
            foreach ($addresses as $address) {
                $addressData = $this->objectCopyService->copyFieldsetToTarget(

                /** @var \Magento\Customer\Api\Data\AddressInterface $customerAddress */
                $customerAddress = $this->addressFactory->create(['data' => $addressData]);
                switch ($address->getAddressType()) {
                    case QuoteAddress::ADDRESS_TYPE_BILLING:
                    case QuoteAddress::ADDRESS_TYPE_SHIPPING:

                if (is_string($address->getRegion())) {
                    /** @var \Magento\Customer\Api\Data\RegionInterface $region */
                    $region = $this->regionFactory->create();
                $customerData['addresses'][] = $customerAddress;
            $account    = $this->createUser($customerData, $websiteId, $storeId, (int)$this->getRequest()->getParam('group'), $count);

            ->setData('customer_group_id', $account->getGroupId())
            ->setData('customer_is_guest', 0)
            ->setData('customer_firstname', $account->getFirstname())
            ->setData('customer_lastname', $account->getLastname());



Guest Checkout

Your store can be configured to require shoppers to open an account before making a purchase. The default setting allows guests to make purchases, with an option to register for an account after they complete the checkout process.
