What it means
When the seller has a Swedish address and gives a company registration number (BT-30), it must have exactly 10 characters after leading and trailing whitespace is removed and internal runs of whitespace are collapsed to one space. With the hyphen (556677-8899) it has eleven characters, and the VAT number (SE556677889901) has fourteen, so both fail. This rule checks length, not whether the characters are numeric.
Why it matters
Peppol BIS Billing 3.0 requires the company registration number to have 10 characters when the seller has a Swedish address and provides the number.
How to fix it
In the seller's company details, enter the organisation number as ten digits, for example 5566778899. If you copied the VAT number into this field, replace it with the organisation number from your company registration. The VAT number belongs in the VAT number field (BT-31).
