What is the EORI number in Luxembourg?
Luxembourg's customs authority, Administration des douanes et accises (Luxembourg Customs), identifies traders using the EORI (Economic Operators Registration and Identification) number — a single reference quoted on every customs declaration. The number takes the form LU plus a national identifier, shaped like LU12345678, and once issued it is recognised for customs purposes across the whole EU, not just Luxembourg. No EORI on file means no import or export can be declared under your name.
Who needs an LU EORI number?
The rule is simple: if you're established in Luxembourg and your name appears on a customs declaration as importer or exporter, you need an EORI number first. That applies whether you're a limited company, a sole trader or a partnership, and whether the goods are inbound stock from outside the EU, outbound sales to overseas customers, or cross-border orders placed through an online marketplace. A forwarder or courier can submit the declaration on your behalf, but it will still show your EORI, not theirs.
There is only one place to register: the EU member state where your business is legally established. For a company based in Luxembourg, that is Administration des douanes et accises (Luxembourg Customs). The LU-prefixed EORI it issues is then usable on customs declarations across the entire EU, all 27 member states, so there's no need to apply again elsewhere in the bloc. A non-EU business can likewise obtain its EORI in Luxembourg if that's where it first lodges an EU customs declaration.
Great Britain sits outside this EU-wide recognition, so a LU EORI on its own will not clear a UK import. If your Luxembourg business imports into the UK in its own name, apply separately to HMRC for a GB EORI — see our UK EORI guide.
How to apply for an EORI number in Luxembourg
- Check whether you already have one. Authorities often assign EORI
numbers automatically when a business first interacts with customs. Search old customs
correspondence or ask your forwarder, and try our
EORI checker with your likely number — the
format is usually LU plus your national tax or business identifier.
- Gather your business details. You will typically need your company
registration number, VAT or tax ID, legal form, registered address and contact details
of an authorised person.
- Apply with Administration des douanes et accises (Luxembourg Customs).
Applications go through the official
portal — often prompt for complete applications.
Registration is free of charge; no official authority charges for
issuing an EORI.
- Validate before your first shipment. Once issued, confirm the number
is active with our free checker so your
first declaration is not rejected over a typo or a not-yet-propagated registration.

Checking and using your Luxembourg EORI number
EU EORI validation (EU EOS) + Luxembourg customs confirmation. Because the EOS database behind LU numbers is EU-wide, not just Luxembourg's own system, counterparties anywhere in the bloc can look your number up too — a routine step many businesses take before trading with a new supplier or customer.
Once active, your EORI appears on every customs document tied to your business: import and
export declarations, transit paperwork, safety and security filings, and any customs
authorisations you hold. Couriers such as DHL, FedEx and UPS will ask for it before they
can clear commercial goods in your name. Keep the exact string handy in your shipping
profiles — a single mistyped character is enough to stop a consignment at the border. You
can compare your number against the national pattern in our
EORI format hub, which covers every country's
structure with valid examples.
