Reference numbers

Various reference numbers:

  • It must be possible to connect it to the importers records as well as to the goods delivery and to the amount invoiced or to be invoiced. 
• Trader reference number LRN (‘Local Reference Number’)
  • Unique reference number for the declaration provided by the declarant.
• Customs’ reference number MRN (‘Master Reference Number’)
  • Customs’ reference number for the declaration, which is generated by the Customs Clearance Service when the declaration is received for processing in the service. Replaces the customs clearance number that Customs previously issued in customs clearance decisions.

If there is no additional document or the document doesn’t have a reference number, the presentation notification date provided by the transport company can also be used as the reference number.
