I need to make lastname optional in customer registration form.

2 Answers 2


First of all you should remove the is_required option from the lastname attributes in the customer entity and address entity:

UPDATE `eav_attribute` SET `is_required`=0 WHERE `attribute_code`='lastname'

Then you should rewrite registration form of your theme. In the default magento setup this template is located here:


You should remove validation and required class from the lastname label and lastname input, like:

<div class="field field-name-lastname">
    <label class="label"  for="<?php /* @escapeNotVerified */ echo $block->getFieldId('lastname') ?>">
        <span><?php /* @escapeNotVerified */ echo $block->getStoreLabel('lastname') ?></span>

    <div class="control">
        <input type="text" id="<?php /* @escapeNotVerified */ echo $block->getFieldId('lastname') ?>"
               name="<?php /* @escapeNotVerified */ echo $block->getFieldName('lastname') ?>"
               value="<?php echo $block->escapeHtml($block->getObject()->getLastname()) ?>"
               title="<?php /* @escapeNotVerified */ echo $block->getStoreLabel('lastname') ?>"
               class="input-text <?php /* @escapeNotVerified */ echo $block->getAttributeValidationClass('lastname') ?>" <?php /* @escapeNotVerified */ echo $block->getFieldParams() ?>>

Important Note: Do not change the original file! You should do it in a custom module or theme!

  • Hi Siarhey Uchukhlebau, thanks for quick reply. it works fine, but i am importing customers from m1 to m2, while importing some of the customers are not imported, why because customer last name was empty. But your solution works fine in frontend, any idea to fix while importing data.

I think that it would be better to update the


option through upgrade script instead of run a query directly on database.

You should create in your module an UpgradeData.php in this path


and put inside this code


namespace Vendor\Module\Setup;

use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Customer\Model\Customer;
use Magento\Customer\Setup\CustomerSetupFactory;

class UpgradeData implements \Magento\Framework\Setup\UpgradeDataInterface
    private $customerSetupFactory;

    public function __construct(
        CustomerSetupFactory $customerSetupFactory
        $this->customerSetupFactory = $customerSetupFactory;

    public function upgrade(ModuleDataSetupInterface $setup,
                            ModuleContextInterface $context)

        if (version_compare($context->getVersion(), '1.0.1', '<=')) {
            $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
            $customerSetup->updateAttribute(Customer::ENTITY, 'lastname', 'is_required', 0);


Then run bin/magento setup:upgrade to apply to database

  • This updates the DB Entry, but does not pass through the JS validation in admin panel.
