Frequently asked questions
Do I need an EORI number?
You need an EORI (Economic Operator Registration Identification) if you perform customs activities in the EU, such as lodging import/export declarations, entry/exit summary declarations, or applying for an AEO certificate. If you're established in the EU and trade internationally, you need one.
Is an EORI number valid across all EU member states?
Yes. An EORI number is unique across the entire EU and valid in all member states. You do not need separate numbers for each country. The number follows the format: country code (2 letters) + member state identifier (up to 15 alphanumeric characters).
How do I validate my EORI syntax?
EORI syntax rules vary by member state. The format is always the 2-letter country code plus a national identifier of up to 15 characters. Germany issues DE followed by up to 15 digits (newer numbers use all 15). France uses FR plus the 9-digit SIREN. This tool checks the structure only; confirm the number is active with the EU EORI validation service before you file.
