Bulk check
Checked on your device
Explanation
Bulk check in three steps
Paste your list
One number per line, straight from a spreadsheet or a text. Empty lines do not count.
Let Handig Belgium guess or choose
Handig Belgium recognises each line. If you are sure, choose IBAN, VAT, communication or national number yourself.
Take the result along
Per line valid or not, with the tidy form or the reason. With Handig Plus you download it all as CSV for Excel.

Good to know
Does my list go to a server?
No. The whole check happens on your device, national numbers too. That is why the bulk check does not ask VIES: that would send your whole customer list out. Do that number by number in the VAT tool.
What does valid mean?
That the number is well formed: the length and the check digits are right. Whether an account exists or a company is active, this check does not say.
How many lines can I paste?
Free up to 20 lines at a time, with Handig Plus up to 5000. The table shows the first 300; the CSV holds them all.
