Bulk VAT Validator
Paste a list of VAT numbers, one per line. We'll check each one against VIES, ARES and MFCR, and for Czech entities also check the unreliable VAT payer status.
EU-wide
VAT numbers
One VAT number per line. Duplicates and header rows (e.g. "VAT number") are removed automatically.
Frequently asked questions
The tool handles hundreds of VAT numbers; PDF/Excel export is limited to 1000 records — if you exceed it, only the first 1000 are exported.
The VIES registry can be temporarily overloaded. Use the "Retry errors" button to re-check only the rows that failed.
For every valid Czech VAT number we automatically check the MFCR unreliable payer registry and show the result in the "Unreliable payer" column.
