The API returns data validating an EU VAT number, including the registered company name, address, and the standard VAT rate for the corresponding country.
Key fields in the response include "validity" (true/false), "company name," "address," and "VAT rate." These fields provide essential information for verifying VAT numbers.
The response data is structured in a JSON format, with fields clearly labeled for easy access. Each response includes a status indicating validity and detailed company information.
The endpoint provides information on VAT number validity, the associated company name, address, and the applicable VAT rate for the country of registration.
Typical use cases include verifying supplier or customer VAT numbers before invoicing, checking VAT IDs for reverse charge transactions, and confirming company details from VAT numbers.
Data accuracy is maintained by sourcing information from the official VIES register, which is regularly updated by the European Commission to ensure reliable validation.
Users can customize their requests by specifying the VAT number they wish to validate. The API accepts a single VAT number as a parameter for verification.
If results are partial or empty, users should verify the VAT number format and ensure it is valid. Additionally, check if the number is registered in the VIES database, as unregistered numbers will return no data.
