Package Exports

@salespark/validate-vat-eu
@salespark/validate-vat-eu/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@salespark/validate-vat-eu) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm registry notice: On 2 May 2026 (timezone Europe/Lisbon), this package will no longer be publicly installable from the npm registry and will become restricted to the SalesPark npm organization. Until then, already-published versions remain public. No further public releases or support for external consumers is planned — if you depend on this package, fork before that date.

🧾 API

`validateVatEU(countryCode: string, vatNumber: string, timeoutMs?: number): Promise<VatCheckResult>`

Validates a European VAT number using the official VIES SOAP API.

Parameters

Parameter	Type	Description
`countryCode`	`string`	Two-letter ISO 3166-1 alpha-2 country code (e.g. `'PT'`, `'DE'`)
`vatNumber`	`string`	VAT number without the country prefix (digits or alphanumeric, no spaces)
`timeoutMs`	`number`	Optional request timeout in milliseconds (default: `7000`)

Returns

A Promise that resolves to the following object:

interface VatCheckResult {
  countryCode: string;
  vatNumber: string;
  valid: boolean;
  name: string;
  address: string;
  requestDate: string;
}

📝 Notes

Only VAT numbers registered for intra-community operations will return valid: true.
Some VAT numbers that are valid at national level might not be registered in the VIES system.
VIES service availability may vary — it's not guaranteed to be 100% online.
This package uses the official SOAP endpoint:
https://ec.europa.eu/taxation_customs/vies/services/checkVatService

🧪 Testing

You can test with a known valid VAT number:

validateVatEU("PT", "502011378"); // Should return valid: true

🛠 Built With

Node.js https – native module for secure HTTP requests
