Frequently asked questions

What does the TaxID API return for a Malta VAT validation?

For a valid Malta VAT number the API returns: `valid: true`, `status: "active"`, plus `company_name` and `address` where available from EU VIES (real-time). For invalid numbers it returns `valid: false` with a reason code. All fields are documented in the API reference.

How fast is the Malta VAT validation API?

Cached results (valid numbers are cached 24h, invalid 1h) respond in under 10ms. Uncached requests that require a live lookup via EU VIES (real-time) typically complete in 100–400ms. The `cached` field in the response tells you whether the result came from cache.

What is the Malta VAT number format?

Malta VAT numbers (VAT registration number) follow the pattern: MT + 8 digits. A valid example is `MT12345678`. The TaxID API validates the format locally before making any live request, so malformed numbers fail instantly without consuming your quota.

Can I validate multiple Malta VAT numbers in one request?

Yes. The batch endpoint (POST /api/v1/validate) accepts up to 25 VAT numbers in a single request, processed in parallel. This is ideal for bulk onboarding flows, nightly reconciliation jobs, or importing customer lists. Each item in the response array maps 1-to-1 with your input array.
