1 of 5 measures had too little evidence to score. They are left out of the total rather than counted as zero — otherwise a plugin would be marked down for being small rather than for being poorly kept.Measured 2026-08-01 from the WordPress.org plugin registry.

Every rating WordPress.org holds for this plugin, not a sample. Written reviews live in the plugin's WordPress.org reviews forum.

Adds Company & VAT numbers (IČO & DIČ & IČ DPH) to WooCommerce billing fields and verifies if data are correct. Verification is based either on ARES and VIES database or only on mathematics. When billing to Czech republic, you can autofill fields Company, VAT number, Address, City, and Postcode based on IČO.

The plugin doesn’t support block checkout. [Use shortcode checkout instead or “Classic checkout block”.] (https://kybernaut.cz/clanky/jak-vratit-starou-woocommerce-pokladnu-misto-noveho-bloku/)

Supports both PHP 7.3+ (soon to be abandoned) & PHP 8.0+.

Main functionality

  • for CZ as billing country
    • ARES and VIES verification (or mathematically verifies IČO and DIČ)
    • ARES autofill (fields Company, VAT number, Address, City, and Postcode) based on IČO
  • for SK as billing country
    • VIES DIČ validation (or just validate the format of values)
  • for EU countries as billing country
    • VIES DIČ validation
  • VAT exempt feature
  • adds fields to IČO & DIČ & IČ DPH WooCommerce frontend: Checkout and My Account page
  • allows edits from administration (backend):
    • Users -> Joe Doe (Edit) -> Billing address of the customer
    • E-shop-WooCommerce -> Orders-> Order (show(edit)) -> Billing Information (edit)
  • Enable toggle switch to show/hide input fields (“Buying as a company?”)
  • Move Country field above the “Buying as a company?” toggle
  • Option to allow on order if if ARES or VIES check fails for technical reasons – an alert will be shown in the admin mail and order details

I want to display values in Woo iDoklad by Vladislav Musílek (Toret)

Go to Toret plugins -> Woo iDoklad and scroll to Přiřazení polí pro IČ a DIČ and fill following values:
IČ: _billing_ic
DIČ: _billing_dic
SK DIČ: _billing_dic_dph

I want to style ARES verified fields

U can use css selectors .kbnt-validating, .kbnt-ok, and .kbnt-wrong for example:
.kbnt-wrong input {
color: #e2401c;
}
.kbnt-ok input {
color: #0f834d;
}
.kbnt-validating input{
color: #3d9cd2;
}

I want to display fields in the same row, one besides other (half width)

You can use this snippet to modify the classes of outputed fileds, just add them to your functions.php

add_filter( 'woolab_icdic_class_billing_ic', 'my_theme_class_billing_ic', 10, 1 );
function my_theme_class_billing_ic ( $class ) {
    return array('form-row-first');
}

add_filter( 'woolab_icdic_class_billing_dic', 'my_theme_class_billing_dic', 10, 1 );
function my_theme_class_billing_dic ( $class ) {
    return array('form-row-last');
}

I want to update customers meta when I change IČO or DIČ value within order edit.

You can use this snippet to update customers data when you edit an order, just add them to your functions.php

add_filter( 'woolab_icdic_update_user_meta', '__return_true' );

How can I report security bugs?

You can report security bugs through the Patchstack Vulnerability Disclosure Program. The Patchstack team help validate, triage and handle any security vulnerabilities. Report a security vulnerability.

I found a bug. Where should I post it?

I personally prefer GitHub, to keep things straight. The plugin code is here: GitHub
But you may use the WordPress Forum as well.
