October 6th, 2026 by Syed Haroon Shah
The importer validation rules for Royal Mail international shipments has been updated to provide greater flexibility when supplying importer details:
- Importer EORI and VAT numbers are no longer mandatory for DTP and IOSS/DTP shipments when importer information is provided.
- Importer VAT numbers are no longer required for DDP B2B shipments when importer details are supplied.
- Customers can now provide importer details that differ from the recipient's details.
- Importer information provided in the shipment request will be passed through and used in downstream customs processes.
