in validateVatNumber method this issue is now solved (line #516 in current version ):

$vat_number = strtoupper(zen_db_prepare_input($_POST['vat_number'] ?? ''));

but in update the unnecessary warnings are still being generated (line # 325 in current version)

$vat_number = zen_db_prepare_input($_POST['vat_number']);

Thanks for the report; I've created a GitHub issue to track the required change: https://github.com/lat9/vat4eu/issues/50

Actually, if that field's missing that implies a possible misconfiguration, since VAT4EU's observer should have inserted some jQuery that will add the vat_number entry field to those forms.

What template is in use and is the configuration setting Customer Details :: Company set to true?

What template is in use and is the configuration setting Customer Details :: Company set to true?

Customer Details :: Company ('ACCOUNT_COMPANY' key) is set to false

(I do put corporate customers having EU-VAT-# manually from Admin )

I use my own template (but this does no matter here, I think)

OK, that would be why the vat_number isn't getting posted, since the customer's Company field needs to be displayed on the storefront for the VAT number to be included.
