Due to advances in technology, international trade and business have been steadily climbing over the past couple decades. Increased online interactions have done their part to make the world smaller and trade prospects wider, and while the pandemic hit the global trading business hard last year, the World Trade Organization is projecting a boost of 8.0% in 2021.

In order to position your company for successful international business travel and transactions in the upcoming year, Value-Added Tax (VAT) regulations must be considered. The European Union requires businesses to be registered with a VAT identification number on the VAT Information Exchange System; if the business is not registered, then they are not eligible to trade within the EU. To internally validate VAT registration, the following API will allow your systems to parse and verify input VAT numbers and return contact information for the corresponding business. Each VAT number should begin with the two-letter ISO country code; possible country codes include Austria (AT), Belgium (BE), Bulgaria (BG), Cyprus (CY), Czech Republic (CZ), Germany (DE), Denmark (DK), Estonia (EE), Greece (EL), Spain (ES), Finland (FI), France (FR), United Kingdom (GB), Croatia (HR), Hungary (HU), Ireland (IE), Italy (IT), Lithuania (LT), Luxembourg (LU), Latvia (LV), Malta (MT), The Netherlands (NL), Poland (PL), Portugal (PT), Romania (RO), Sweden (SE), Slovenia (SI), and Slovakia (SK).
