VAT ID checker
Check the technical format of an EU VAT ID and see the expected structure without a live VIES lookup.
Check VAT ID
The check is done in your browser. The identifier you enter is not sent to the server.
This checker validates the format and check digits where applicable. It does not perform a live VIES lookup or confirm company existence, name, address, registration status or VAT registration validity.
EU VAT ID format
The VAT ID checker validates EU/VIES-style country codes and national VAT ID formats where the project has a technical rule for the format.
Format and check digits
The checker can normalize input, show the expected format and apply check-digit rules where applicable. It is useful for catching typing mistakes before using a VAT ID elsewhere.
Country codes and format messages
The result can show a readable format requirement, such as a country code followed by a required number of digits. This helps fix obvious length or country-code mistakes.
When to use an official lookup
Use an official VAT validation service or the counterparty's own documents when you need confirmation of VAT registration, company details or transaction-specific tax treatment.
No live VIES lookup
This checker validates the format and check digits where applicable. It does not perform a live VIES lookup and does not confirm a company name, address, registration status or business existence.
