​
Routing

  • EU countries (including XI) are validated via the VIES service
  • GB is validated via the HMRC API

​
Input normalization

The API automatically normalizes VAT numbers before validation:
  • Uppercase: nl123456789b01 becomes NL123456789B01
  • Strip spaces: NL 123 456 789 B01 becomes NL123456789B01
  • Strip dots: NL123.456.789.B01 becomes NL123456789B01
  • Strip hyphens: NL-123456789-B01 becomes NL123456789B01
You can pass messy input and the API handles the rest.
Greece uses EL as its country code (not GR). This follows the EU VIES convention.
