Supported Jurisdictions & Validation Meanings

BulkVAT supports 30 tax jurisdictions. Because tax rules differ fundamentally across borders, this guide details exactly how each country is evaluated and what each status code means.

Mandatory Compliance Notice: BulkVAT is an automated data formatting and query utility. Passing an offline format or checksum check confirms mathematical structure only and does not confirm that a business is actively registered with tax authorities. Official VIES responses reflect the live status of national databases at the time of query.

Understanding Status Output Codes

  • VALID (VIES): The number was confirmed as actively registered in the European Commission VIES database. Adjacent columns contain registered company name, address, and consultation ID.
  • INVALID (VIES): The number has valid syntax but was reported as not registered or inactive by the member state's tax authority.
  • VALID (GB FORMAT ONLY - NOT REGISTRATION STATUS): The UK VAT number satisfied HMRC Modulus 97 checksum calculations. Post-Brexit, GB numbers are not part of EU VIES and registration status is not confirmed.
  • VALID (AU ABN FORMAT ONLY): The Australian Business Number passed the ATO Modulus 89 algorithm.
  • VALID (US EIN FORMAT ONLY): The US EIN conforms to IRS campus formatting rules.
  • MS UNAVAILABLE (Retry Later): The upstream national tax database is offline for maintenance. The number has not been marked invalid.
  • INVALID SYNTAX / CHECKSUM FAILED: The number failed mathematical checksum or length constraints.
