Cost, validity and processing time

• The EORI number is free — Slovenian Financial Administration (FURS) does not charge for issuing it.
• It is valid EU-wide. Once any member state has issued your EORI, you do not need another one to declare goods in other EU countries.
• A business established outside the EU registers in the member state where it first lodges a customs declaration or appoints a representative — not necessarily Slovenia.
• Processing normally takes a few working days, though incomplete applications are the most common cause of delay.
