Difference between EORI number and VAT number: checks and limits comes down to using two separate identifiers in the right official databases. An EORI identifies an economic operator for customs formalities; an EU VAT number identifies a taxable person for relevant VAT transactions. A valid result confirms a status at the time of the check, not a partner’s overall reliability or product compliance.
Key takeaways
- An EORI number identifies an economic operator in dealings with EU customs authorities.
- An EU VAT number identifies a taxable person for certain VAT transactions within the European Union.
- The European Commission’s EORI validation service and VIES are separate checks and should be used for different purposes.
- An EORI may resemble a national tax identifier in format, but the two identifiers are not interchangeable.
- A positive validation does not remove the need to check the counterparty, commercial documents, tariff classification and product obligations.
What is the difference between an EORI number and an EU VAT number?
An EORI is a customs identifier, while an EU VAT number is a tax identifier. You should therefore use and verify them for different purposes, even where the same business holds both.
EORI means Economic Operators Registration and Identification. It is assigned by the competent customs authority and identifies an operator in customs procedures, including import, export, transit and other declarations under customs law. Its framework sits within the Union Customs Code, Regulation (EU) No 952/2013 and its implementing rules.
An EU VAT number, by contrast, identifies a taxable person for transactions covered by EU VAT rules. It is used, among other things, to support certain intra-EU business-to-business supplies, prepare invoices and meet related reporting obligations. The general framework is set by Council Directive 2006/112/EC on the common system of VAT.
Imagine a US company shipping accessories from Shenzhen to an Amazon FBA warehouse in Germany. The import requires customs identification of the relevant operator, so the EORI is central. If that company later makes an intra-EU B2B supply to a business customer in another Member State, the EU VAT number and VAT treatment become a separate question.
| Identifier | Main purpose | Where to check it | What the check confirms |
|---|---|---|---|
| EORI | Customs identification | European Commission EORI validation | Availability of publicly consultable EORI data |
| EU VAT number | VAT identification of a taxable person | VIES | VAT number validity on the date checked |
| IOSS | VAT reporting for certain imported consignments | No public validation register | It should not be disclosed as a publicly checkable number |
An IOSS number replaces neither an EORI nor an EU VAT number. It belongs to a specific VAT scheme for certain distance sales of imported goods and should not be shown on a commercial invoice or disclosed to a customer. Before choosing a logistics model, use the EU VAT calculator to compare the VAT treatment of your likely flows.
Who needs to check an EORI number or EU VAT number?
You should check an EORI where a customs operation depends on identifying an operator. You should check an EU VAT number where your VAT treatment depends on confirming the counterparty’s status. Ecommerce sellers, importers, manufacturers, freight forwarders and professional buyers may all need to do this.
Importers and sellers bringing goods into the EU
If you import stock into the European Union, an EORI is generally the identifier expected in customs formalities. This also applies where goods are sent directly from a non-EU country to a European fulfilment warehouse. A customs agent preparing the declaration does not mean your business has no responsibility for the information supplied.
Before your first shipment, identify the importer, the customs-clearance country, the tariff classification and the customs value. The EU stock import guide for ecommerce sellers helps you put those steps in the right order.
B2B buyers and sellers operating across Member States
For an intra-EU B2B transaction, checking a customer’s or supplier’s EU VAT number may be necessary to support the VAT treatment you apply. Keep a dated record of the result, together with the available details, in your accounting and commercial file.
That precaution does not establish that the business is creditworthy, that it is the real manufacturer or that its products meet safety rules. To review declared identity, payment details and documentary inconsistencies before placing an order, you can use Supplier Check.
EU Seller Kit — Before a first EU shipment, the EU Market Entry Compliance Assessment helps you identify the customs, VAT and product checks relevant to your business, goods and storage countries.
When do EORI and VAT apply in an ecommerce journey?
EORI applies when customs formalities are completed; VAT depends on the sale, where the goods are located, the customer and the scheme used. One shipment can therefore raise both issues without making their rules the same.
Take a French seller buying goods in China and having them delivered to France. When the goods enter the EU, the customs declaration uses customs data, including the EORI of the relevant operator. Import VAT is a separate tax issue; later sales to French consumers are then subject to French VAT rules.
Consider another scenario: a non-EU seller stores products in Poland and sells them to consumers in France and Spain. The EORI mattered at the initial import. Afterwards, the VAT arrangement depends in particular on the storage and sales locations, as well as any scheme used. The European Commission explains OSS and IOSS mechanisms on its official OSS/IOSS portal.
In practice, an EORI does not create a VAT registration, and a VAT registration does not replace the EORI needed for a customs declaration. If your goods move between several storage or destination countries, use Country Compliance to organise the points to check by country.
Great Britain has operated its own customs system since leaving the EU. An EORI issued in the EU is not automatically a GB EORI. If you import, export or move goods through Great Britain, consult the EU and GB EORI guide and GOV.UK guidance on getting an EORI number.
How do you check an EORI number and EU VAT number step by step?
Always use the official register that matches the identifier, then retain the result with the context of the transaction. A documented check is more useful than an isolated screenshot with no date or commercial reference.
Check an EORI number
The European Commission provides an official EORI validation service. Enter the number provided, preserving its country prefix and format. The information displayed may depend on the operator’s publication settings and the national administration.
If the result is invalid or unavailable, do not guess a correction. Ask the operator to confirm its identifier with the authority that issued it, compare the legal name against the commercial documents and check whether the flow genuinely concerns that operator. The European Commission’s EORI guidance explains the role of EORI.
Check an EU VAT number
For VAT, use the European Commission’s VIES system. Select the Member State that issued the number, enter it without changing its structure, then retain the result. VIES queries national databases, so a temporary service outage does not necessarily mean that the VAT number is invalid.
Where the result is negative, pause the intended VAT treatment until you have clarified the position. Contact your counterparty, request written confirmation and, where needed, check with the competent tax authority or your tax adviser. The number may be incorrect, inactive for intra-EU transactions or linked to circumstances requiring a closer review.
Checklist before an import or B2B sale
- Identify the entity acting as importer and the entity lodging, or arranging the lodging of, the customs declaration.
- Check the EORI in the European Commission’s official tool where the customs flow requires it.
- Check the EU VAT number in VIES where the VAT treatment depends on the counterparty’s status.
- Record the date, result, number checked and the related order or invoice reference.
- Compare the legal name and address with the commercial invoice, contract and bank details.
- Determine the tariff code before customs clearance and confirm it in the applicable nomenclature.
- Check product safety, labelling and representation requirements before placing the product on the market.
To identify candidate subheadings before confirming them in the Combined Nomenclature or TARIC, use the HS classification assistant. Classification determines, among other things, which tariff and regulatory measures you need to review; the official consultation point is TARIC.
Which documents should you compare with a validation result?
A validated identifier is useful only if it matches the transaction and the entity actually involved. Compare it with commercial, customs and logistics documents before paying, importing or invoicing.
For an EORI, check at least the operator’s legal name, declared address, commercial invoice, agreed Incoterm, importer role and instructions given to the customs representative. An incomplete commercial invoice can delay customs clearance even where the EORI is valid. Use the EU import customs documents checklist to structure your file.
For an EU VAT number, compare the VIES result with the invoice, purchase order, customer’s legal details and transport evidence where your VAT treatment requires it. The check should concern the contracting entity, not an affiliated company or a trading name shown only on a website.
Example: a supplier gives you a German VAT number but asks for payment to an account held by a different company outside the EU. VIES may confirm that the German number is valid without explaining that mismatch. You should request the necessary evidence before proceeding, because VAT validation does not confirm the identity of the payment beneficiary.
What effort is involved, and what are the limits of these checks?
Checking an official register is quick, but making a sound commercial and tax decision requires wider document checks. The real effort often lies in preparing reliable data before dispatch, rather than entering a number into a form.
For EORI, you will generally need to gather company identification information and determine the competent customs authority. The EORI file preparation service helps prepare an application file. It is a one-time service unless included in a SaaS plan quota, and the number itself is issued by the competent customs authority. See pricing and plans for available plans and add-ons.
For VAT, the effort depends on your sales model: domestic sales, stock held in several Member States, B2B transactions, distance sales or imports. A calculator can help compare scenarios, but it does not replace an assessment of your tax position or filing obligations with the relevant authorities.
The central limit is straightforward: neither VIES nor EORI validation is a complete due-diligence tool. Neither checks product quality, intellectual-property rights, financial capacity, CE compliance, GPSR obligations or the authenticity of every document provided.
Which common mistakes and special cases should you avoid?
Do not infer an obligation or exemption from a number’s format alone. The costliest errors often arise from confusing customs roles, VAT status and product responsibility.
Confusing EORI, VAT and IOSS
A common mistake is giving an IOSS number to a supplier, carrier or customer as if it were an EORI. These identifiers do not have the same function. IOSS concerns a VAT reporting scheme for certain distance sales of imported goods; EORI is for customs identification.
Assuming a valid EORI authorises the sale of a product
A valid EORI does not show that a product may be placed on the EU market. For consumer products, Regulation (EU) 2023/988, the General Product Safety Regulation, sets product-safety and traceability obligations. For product categories covered by EU harmonisation legislation, CE marking may be required; Your Europe’s CE marking guidance outlines the general principles.
A non-EU manufacturer selling an electronic device may therefore need an EORI for import, an appropriate VAT arrangement for its sales, and compliance documentation under the Radio Equipment Directive, Low Voltage Directive or EMC Directive, depending on the product. These are separate workstreams. A Marketplace Product Compliance Scanner can flag traceability and safety information to review before publication; it does not replace the manufacturer’s conformity assessment.
Assuming a subscription automatically appoints an EU representative
A SaaS subscription does not automatically appoint a GPSR responsible person or a CE authorised representative. For a non-EU seller of consumer products, the GPSR Responsible Person service becomes active only after acceptance, entity assignment, a signed mandate and active payment. For CE-marked products, a CE Authorised Representative does not replace the manufacturer’s conformity assessment, testing, technical documentation or EU declaration of conformity.
Overlooking Great Britain and Northern Ireland flows
EORI rules differ depending on whether your flow concerns the EU, Great Britain or Northern Ireland. Do not reuse an identifier without checking the territory and direction of movement. The GB and XI EORI guide sets out the points to review before shipping.

Frequently asked questions
Is an EORI number the same as a VAT number?
No. An EORI identifies an operator for customs formalities, whereas an EU VAT number relates to VAT obligations. They may share elements of their format in some countries, but they remain legally and operationally distinct identifiers.
Can you check an EORI number in VIES?
No. VIES checks EU VAT numbers. To check an EORI, use the European Commission’s EORI validation service or request confirmation from the competent customs authority where public data is insufficient.
Does a valid VIES result prove that a supplier is reliable?
No. A valid result confirms that the VAT number is recognised by the system when checked. It does not prove product quality, the identity of the payment beneficiary or the regulatory compliance of the goods.
Do you need an EORI if you sell only to consumers in the EU?
It depends on your logistics flow. If goods enter the EU from a non-EU country under your responsibility, or under that of the operator you have appointed, customs formalities may require an EORI. If your stock is already in free circulation in the EU, the consumer sale itself does not necessarily create a new customs formality.
What should you do if a partner’s EORI is invalid?
Ask the partner to confirm the number and the entity that should use it, then check that the commercial documents match. Do not substitute another identifier without clear instructions: an inaccurate customs declaration can lead to a hold or a request for correction.
Can an IOSS number be given to a carrier?
Within the appropriate operational process, an IOSS number may be passed to the intermediary that needs it for the relevant declaration, following established procedures. It should not be displayed publicly or shared with the customer, because misuse can compromise the scheme. Ask your intermediary and tax adviser which secure transmission method applies to your flow.
