Magento is using EU VIES (VAT Information Exchange System) service to validate the VAT-IDs (http://ec.europa.eu/taxation_customs/vies/checkVatService.wsdl)

Is it reliable and how Magento is using it?

As VIES/Web team proposes following recommendation to ensure validation can be performed without blocking:

  1. you perform 20k or less requests for VAT validations per day,
  2. you perform up to 5 validations to a unique VAT number per day,
  3. you avoid performing blank or null or white space or corrupted or invalid (syntax, length) validations
  4. you perform validations preferably until 10:00 am CET and/or after 18:00 CET
