namespace Test\Customer\Setup;

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

class InstallData implements \Magento\Framework\Setup\InstallDataInterface
    private $eavSetupFactory;
    private $eavConfig;
    private $attributeResource;
    public function __construct(
        \Magento\Eav\Setup\EavSetupFactory $eavSetupFactory,
        \Magento\Eav\Model\Config $eavConfig,
        \Magento\Customer\Model\ResourceModel\Attribute $attributeResource
    ) {
        $this->eavSetupFactory = $eavSetupFactory;
        $this->eavConfig = $eavConfig;
        $this->attributeResource = $attributeResource;
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
        $eavSetup = $this->eavSetupFactory->create(['setup' => $setup]);

        $eavSetup->removeAttribute(Customer::ENTITY, "gst_number");

        $attributeSetId = $eavSetup->getDefaultAttributeSetId(Customer::ENTITY);
        $attributeGroupId = $eavSetup->getDefaultAttributeGroupId(Customer::ENTITY);

        $eavSetup->addAttribute(Customer::ENTITY, 'gst_number', [
            // Attribute parameters
            'type' => 'varchar',
            'label' => 'GST number',

        $attribute = $this->eavConfig->getAttribute(Customer::ENTITY, 'gst_number');
        $attribute->setData('attribute_set_id', $attributeSetId);

You have to override edit.phtml in your theme or in your module you can copy from this location and add field according to your need -


add this code above checkbox -

<div class="field gst required" data-container="change-gst">
            <label class="label" for="gst"><span><?= $block->escapeHtml(__('gst')) ?></span></label>
            <div class="control">
                <input type="text" name="gst" id="gst" autocomplete="gst" data-input="change-gst" value="" title="<?= $block->escapeHtmlAttr(__('Gst')) ?>" class="input-text" data-validate="{required:true}" />
