Autofill Slovak company billing details in WooCommerce admin orders using the RÚZ public API by IČO or DIČ.
This plugin adds an admin order metabox where you can enter IČO or DIČ and fetch company details from the RÚZ (Register účtovných závierok) public API.
It fills billing company name, street, city, postcode, and country, and it can also fill custom order meta fields for IČO, DIČ, and IČ DPH based on your setup (for example WPify Woo or Superfaktura). You can configure the meta field keys in the plugin settings.
For customers
An optional “Load from IČO” widget can be enabled on the WooCommerce checkout page. Customers enter their IČO (8-digit company ID) and click the load button — the billing company name, address, city, postcode, and country are filled in automatically. Works with both the classic WooCommerce checkout and the Gutenberg blocks-based checkout. Enable this feature in WooCommerce IČO priradenie settings.

External Services
This plugin connects to the public API of the Register of Financial Statements (RÚZ) at registeruz.sk to retrieve company details.
When an administrator enters an IČO (Company ID) or DIČ (Tax ID) in the order edit screen and clicks “Load from RÚZ”, the plugin sends that identifier to the API and receives company data (company name and address details).
Data sent: IČO or DIČ entered by the administrator.
When: only on manual request (button click) — in wp-admin by an administrator, or on the checkout page by a customer if the checkout widget is enabled.
Purpose: auto-fill billing company fields in the WooCommerce order edit screen or on the checkout page.

This plugin also connects to the EU VIES (VAT Information Exchange System) service operated by the European Commission to verify whether a company is a registered VAT payer.
After company data is loaded, the plugin sends the VAT identifier (IČ DPH / DIČ with a country prefix, e.g. SK1234567890) to VIES and receives back whether the VAT number is valid, plus the registered name and address.
Data sent: the VAT identifier derived from the loaded company (IČ DPH or DIČ).
When: automatically as part of a manual “Load” request (button click), only after company data is fetched. Results are cached to limit the number of calls.
