I am an authorised warehousekeeper. What ID do I need to register for EMCS?

To register you'll need your Excise Registration Number. This should be the warehousekeeper excise ID. This is a 13 alpha-numeric character reference starting with GBWK and can be found on your approval letter.

The warehousekeeper excise ID is the consignor/consignee reference. The warehouse excise ID is the place of dispatch/place of delivery.

If you don't know your warehousekeeper excise ID you should contact the National Verification Centre on 0141 555 3616 or email
