Registered export customer search

With the registered export customer search, you can find out

  • if a business has registered as an export customer
  • the customer ID extension (e.g. T0001) needed in export declarations 
  • the office details of the business.

We recommend that all exporters register as export customers. Registration is mandatory for exporters with at least five export consignments per year. Read more about how to register
