Economic Operators Registration and Identification system is a database of enterprises that run business on the territory of the EU.
If there is no EORI number, customs clearance is impossible. In this case goods will be stuck at customs or even returned to sender.
The code is a 17-digit number (2 letters denoting the state, 10 digits, and again 5 letters).
This number is unique and each company engaged in foreign economic activity has the opportunity to receive only one. It is applicable throughout the EU.
