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.
What the VAT ID checker shows
The checker shows the normalized VAT ID, country code, country name, expected format requirement, actual length and whether the value matches a supported technical format. Where a supported check digit rule is available, the result also shows whether the check digit matches.
How to use the checker
Enter an EU VAT ID with its country code, such as FI, SE or DE. The checker removes spaces, converts letters to uppercase and compares the value with the technical rule for that country.
What is checked
The checker validates the country code, allowed characters, length and basic country-specific pattern. For countries where this tool supports a check digit rule, the result also shows whether the check digit matches. For other countries, the check is mainly format-based.
Format and check digits
EU VAT ID formats differ by country. Some use only digits, while others allow letters or several length options. The result panel shows the requirement as a readable rule, such as a country code plus a digit count, instead of showing a made-up VAT ID.
Examples
- SE559016123701 matches the Swedish technical format: SE + 12 digits.
- FI07654322 matches the Finnish VAT ID format and a supported check digit rule.
- DE123456789 matches the German technical format: DE + 9 digits.
Limitations
This checker does not perform a live VIES lookup, tax authority lookup or other official register request. A technically valid value does not confirm that a company exists, that it is registered for VAT, that a name or address is correct or that a particular transaction has the right tax treatment. The tool does not provide tax advice, accounting advice or legal advice.
FAQ
What does the checker validate?
It checks the country code, allowed characters, length and country-specific basic format. Where a supported check digit rule is available, it also checks whether the check digit matches.
Can I type the country code in lowercase?
Yes. The checker converts letters to uppercase before validating the VAT ID.
Does this replace a VIES check?
No. Use VIES or the relevant authority service when you need official or business-critical confirmation.
Does a valid format mean the company is registered for VAT?
No. The result only concerns technical format and check digits where applicable. It does not confirm a company name, address, registration status or business existence.
