Odd help request - Paganello

My team ordered jerseys from a vendor in the Philippines to be delivered directly to Italy to await our arrival from the US. The vendor used DHL, which requires a form to be filled out in order for the package to pass customs. On the form is a field for a "private tax code," AKA a "Taxpayer ID number." Not being an Italian citizen, I don't have that, so I'm afraid my package will get held up at customs. Anyone have experience with this and can advise?
