Where do US booksellers put the IOSS # on the customs form if the order is going to a EU country?

Modified on Wed, 12 Nov at 12:45 PM

United States senders should provide the IOSS VAT Identification Number in the “Importers Reference” fields when sending to an EU country. This does not apply with consolidated shipping or via DHL.


*Please be sure to indicate Biblio, Inc. as your name when filling out the customs form to ensure the package goes through customs successfully. Customs will deny your package if you do not put Biblio, Inc. on it, and the package will be returned to you.
