Well i would suggest to use Automatic Dependency injection but if you are using object manager then you can do it like this

//Get Object Manager Instance
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$order = $objectManager->create('Magento\Sales\Model\Order')->loadByIncrementId($IncrementId); //Use increment id here.
$order->getCustomerName(); // Check that class. There are lot of functions for getting customers data. Though first you should check if any API available. Because thats a better solution.
  • Thanks @Kingshuk for giving solution, but i'm not using any api. Apr 3, 2017 at 10:42

    No..not API..Magento said they can change the core code but not the APIs available in near future. If you go to app\code\Magento\Sales the first folder is API. Though you are good to go now. You can use the above code now i guess. But magento can change the core code anytime. Apr 3, 2017 at 10:53

// logined customer
 if ($order->getCustomerFirstname()) {
   $customerName = $order->getCustomerName();
 } else {
  // guest customer
   $billingAddress = $order->getBillingAddress();
   $customerName = $billingAddress->getFirstname() . ' ' . 
echo $customerName;

  • checking customer is guest or not. first name and Last name of the billing address is set as a customer name when the customer is guest.
