Note: For a valid submission of the invoice, you must include either the national Tax Identification Number (NIP) or the Polish EU VAT-ID.

Polish NIP (National ID): Place this in cac:PartyIdentification/cbc:ID. You must include the attribute schemeID='VRBL:PL:TAX' to properly categorize it as a Polish tax identifier.
EU VAT-ID: Place this in the cac:PartyTaxScheme/cbc:CompanyID element. This should typically include the "PL" prefix followed by the 10-digit NIP.

Example of the usage of the Party Identification ID:
