Full checksum is implemented for IT, FR and BE; other countries get a format-only check. For a legally binding check, always confirm active VAT numbers via the official VIES lookup.

The EU VAT Compliance tool is compatible with:Intra-EU B2B InvoicingE-commerce Distance Selling. This tool alone can help you manage and analyze your data effectively. However, a composed workflow using FATTURAPA VALIDATOR, US CA SALES TAX may provide even more powerful data processing capabilities. Consider exploring these related tools for a comprehensive data solution.
Checking a single VAT number against VIES is easy; checking two hundred customer VAT numbers one at a time before your monthly reconciliation is not. This tool runs the actual national checksum algorithm for Italy, France and Belgium locally, and a format check for the rest, so obvious typos and malformed numbers get caught in bulk before anyone touches the official VIES lookup. It's explicit about which check ran on each row — "checksum verified" versus "format looks correct, checksum not verified" — because a format-only pass is a weaker signal than a real checksum, and pretending otherwise would be misleading for something feeding a compliance decision. The second half of the tool tracks the EU-wide €10,000 OSS/IOSS distance-selling threshold that's applied uniformly across all member states since July 2021: feed it a column of per-customer annual sales and it flags the moment your cumulative total crosses into OSS registration territory. Together the two checks cover the two most common EU VAT headaches for a growing e-commerce or B2B seller — is this customer's VAT number even plausible, and have I quietly crossed into needing to register somewhere new.

Frequently Asked Questions:

Which countries get a real checksum vs just a format check?

Full checksum validation runs for Italy, France and Belgium, other EU countries get a format-only check, and the tool tells you which kind ran on each row.

Does passing the checksum confirm the VAT number is active?

No, it confirms the number is well-formed, not that it's currently registered, use the official VIES lookup to confirm active status.
