                ]);
        $attribute->save();
    }
}

After this, if I open New Address from admin customer edit screen or new customer screen, address form is not loading instead error is created in debug.log and system.log as below,

[2021-01-13 11:55:16] main.CRITICAL: TypeError: Argument 2 passed to Magento\Framework\View\Element\UiComponentFactory::argumentsResolver() must be of the type array, null given, called in D:\wamp_new\www\magento_2_4\vendor\magento\framework\View\Element\UiComponentFactory.php on line 235 and defined in D:\wamp_new\www\magento_2_4\vendor\magento\framework\View\Element\UiComponentFactory.php:183 Stack trace: #0 D:\wamp_new\www\magento_2_4\vendor\magento\framework\View\Element\UiComponentFactory.php(235): Magento\Framework\View\Element\UiComponentFactory->argumentsResolver('country_code', NULL) #1 D:\wamp_new\www\magento_2_4\vendor\magento\module-ui\Component\Form\Field.php(85): Magento\Framework\View\Element\UiComponentFactory->create('country_code', 'varchar', Array) #2 D:\wamp_new\www\magento_2_4\vendor\magento\framework\View\Layout\Generator\UiComponent.php(164):

Error on the screen as below,

Where is it going wrong.

Magento 2 customers have different table's for Customer and Customer Shipping/billing Address. Adding the Eav attributes to the customer does not affect the addresses.

What you really want, as much as i know, is to add your attributes to the table: Customer_address_entity

You can try using this code:

public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
{
    $customerSetup = $this->customerSetupFactory->create(['setup' => $setup]);
    $customerAddressEntity = $customerSetup->getEavConfig()->getEntityType('customer_address');
    $attributeSetId = $customerAddressEntity->getDefaultAttributeSetId();

    /** @var $attributeSet AttributeSet */
    $attributeSet = $this->attributeSetFactory->create();
    $attributeGroupId = $attributeSet->getDefaultGroupId($attributeSetId);

    $customerSetup->addAttribute('customer_address', 'is_mobile_verified', [
        'type'         => 'int',
        'label'        => 'Is Mobile Verified?',
        'input'        => 'select',
        'source' => 'Ocra\CustomerMobile\Model\Config\Source\Option',
        'backend' => 'Magento\Eav\Model\Entity\Attribute\Backend\ArrayBackend',
        'required'     => false,
        'visible'      => true,
        'user_defined' => true,
        'position'     => 1002,
        'system'       => 0,
        'default' => 2
    ]);

    $attribute = $customerSetup->getEavConfig()->getAttribute('customer_address', 'is_mobile_verified')
        ->addData([
            'attribute_set_id' => $attributeSetId,
            'attribute_group_id' => $attributeGroupId
        ]);

    $attribute->save();
}
