# Add the EU VAT Field to the Registration Form

To add the EU VAT field to the registration form, go to WPFactory > EU VAT (also reachable at WooCommerce > Settings > EU VAT), General sub-tab, enable Add EU VAT field to sign-up form, and save. EU/UK VAT Manager for WooCommerce then shows the field on the My Account registration form. This is a free feature.

### Turn it on

1. Go to **WPFactory > EU VAT** (also reachable at **WooCommerce > Settings > EU VAT**), on the **General** sub-tab.
2. Enable **Add EU VAT field to sign-up form** (`alg_wc_eu_vat_field_signup_form`).
3. Save changes.

The field now appears on the WooCommerce registration form (My Account) using the same label and placeholder as the checkout field.

### Validate the number at sign-up

To validate the number when the account is created, go to the **Validation** sub-tab and confirm **Validate at sign-up form** (`alg_wc_eu_vat_validate_sign_up_page`) is set to Yes. It is on by default. You can also enable **Validate in "My account"** (`alg_wc_eu_vat_validate_my_account`) so a saved number is re-checked when the customer edits their account details.

### Get more control

This feature is free. [EU/UK VAT Manager for WooCommerce](https://wpfactory.com/item/eu-vat-for-woocommerce/) Pro adds targeting so the field shows only for the countries or user roles you choose. [See what Pro unlocks](https://wpfactory.com/item/eu-vat-for-woocommerce/).
