For eBay orders, eBay collects the destination tax itself and reports the registration it used. Japan Post, FedEx, and UPS already forwarded these references, but DHL did not — so destination customs treated the parcel as tax-unpaid, and the buyer could be charged a second time or the parcel held.
DHL now receives them too, for Australia (ABN Number), New Zealand (IRD Number), Malaysia (SDT Number), Norway (VOEC), and France (TVA).
When eBay reports a reference, it takes precedence over the matching number saved in Settings under Tax registration numbers. Nothing to change on your side.
