I want to set a customer group as first time user for that I am using an observer so that I can update the customer group just after or on the same time of registration.


First create your configuration file in Vendor\Module\etc\frontend\events.xml :

<?xml version="1.0"?>
<config xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="urn:magento:framework:Event/etc/events.xsd">
    <event name="customer_register_success">
        <observer name="persistent" instance="Vendor\Module\Observer\ChangeCustomerGroupId" />

Then create the observer Vendor\Module\Observer\ChangeCustomerGroupId.php


namespace Vendor\Module\Observer;

use Magento\Framework\Event\ObserverInterface;

class ChangeCustomerGroupId implements ObserverInterface
    const CUSTOMER_GROUP_ID = 2;

    protected $_customerRepositoryInterface;

    public function __construct(
        \Magento\Customer\Api\CustomerRepositoryInterface $customerRepositoryInterface
    ) {
        $this->_customerRepositoryInterface = $customerRepositoryInterface;

    public function execute(\Magento\Framework\Event\Observer $observer)
        $customer = $observer->getEvent()->getCustomer();
        if ($customer->getGroupId() == 1) {

NB: don't forget to replace 2 with the id of the customer group you want to use.
