Number Validation:

How to Do It Efficiently

Understanding EORI Numbers and Their Purpose

If you’re involved in international trade within the European Union or the United Kingdom, you’ve probably come across the term EORI (Economic Operators’ Registration and Identification) number. This unique identifier plays a crucial role in customs processes, ensuring the smooth flow of goods across borders. Introduced on July 1st, 2009, the EORI system was designed to streamline and enhance security within the EU’s customs framework. 

Unlike VAT numbers, which are used for tax purposes, an EORI number is specifically required for customs clearance when importing or exporting goods. While businesses within the EU need an EORI number to import goods, companies outside the EU may also require one, particularly if they plan to act as a declarant or carrier.

Why Validating EORI Numbers Is Essential

When engaging in international trade, accuracy is everything. One simple mistake—such as working with an invalid or incorrectly assigned EORI number—can lead to shipment delays, extra costs, and even penalties. That’s why validating an EORI number before completing a transaction is a must. 

Key Reasons to Validate an EORI Number: 

  • Prevention of Shipment Delays: Customs authorities use EORI numbers to track and process shipments efficiently. If an incorrect or invalid number is provided, your goods could be held up at the border, causing delays and additional storage fees. 
  • Avoidance of Financial Disruptions: If an invalid EORI number is used in customs declarations, businesses may find themselves liable for unexpected duties, fines, or reprocessing costs. 
  • Fraud Prevention: Verifying an EORI number ensures that you are dealing with a legitimate company, reducing the risk of fraudulent transactions. 
  • Correct VAT Handling: Since import VAT is linked to an EORI number, ensuring that the number is accurate helps maintain smooth VAT processing, potentially allowing for VAT reclaim where applicable. 

Where to Check an EORI Number

Luckily, you don’t need to navigate a complex bureaucracy to check an EORI number. Both the EU and UK governments provide easy-to-use online validation tools to verify the legitimacy of an EORI number. 

Validating an EU EORI Number

The European Commission provides a free EORI number validation tool for EU EORI Numbers through its Taxation and Customs Union website. Here’s how to use it: 

  1. Visit the EU EORI Validation Tool
  2. Enter the EORI number of your customer or trading partner. 
  3. The system will check if the number is valid and, if so, display details such as the registered company name and address. 
  4. If the number is invalid, double-check with your trading partner or request confirmation from the relevant customs authority. 

Validating a GB EORI Number

Following Brexit, businesses trading with the UK now require a separate GB EORI number for customs clearance. The UK government offers an official EORI validation tool: 

  1. Visit the UK Government EORI Checker. 
  2. Enter the GB EORI number you wish to verify. 
  3. The tool will confirm whether the number is valid and, in some cases, provide additional business details. 

Common Issues with EORI Numbers and How to Resolve Them

Despite the straightforward nature of the EORI validation process, businesses often encounter issues. Here are some common ones and how to resolve them: 

  1. Invalid EORI Number
  • Possible Reasons: The number might have been entered incorrectly, or the business may not have an active registration. 
  • Solution: Double-check the number with your trading partner or ask them to verify their registration status with the relevant customs authority. 
  1. Mismatch Between EORI and Business Details
  • Possible Reasons: A company might have changed its legal name or address, but the EORI records haven’t been updated. 
  • Solution: Request the business to update its details with the customs office where it was registered. 
  1. EORI Number Not Recognised by Customs Authorities
  • Possible Reasons: The number might not be activated for international trade. 
  • Solution: Contact the customs authority that issued the EORI number for further clarification. 

Best Practices for Managing EORI Numbers

To ensure smooth trading operations, businesses should follow best practices for EORI number management: 

  1. Validate Numbers Before Finaliszing Deals

Before agreeing to an international shipment, always verify your trading partner’s EORI number to avoid costly delays or compliance issues. 

  1. Keep EORI Details Updated

If your company changes its legal name, address, or tax registration, ensure that these changes are reflected in your EORI records. 

  1. Automate EORI Validation Where Possible

If your company frequently deals with customs processes, consider integrating an API to reduce manual workload and improve accuracy. 

  1. Stay Informed About EORI Requirements

With regulatory changes happening frequently, staying up to date on EORI-related requirements in the EU and UK will help your business adapt and remain compliant. 

Final Thoughts

Validating EU and GB EORI numbers isn’t just about avoiding customs headaches, it’s about ensuring smooth business transactions, preventing fraud, and keeping your supply chain moving efficiently. Whether you’re a small business starting to trade internationally or a large corporation managing complex import/export operations, having a robust EORI validation process in place will save time, money, and frustration. 

By leveraging official government tools or automating the validation process through APIs, businesses can focus more on growth and less on customs-related complications. In today’s fast-moving trade environment, efficiency is key – and EORI validation is a small yet crucial step in achieving that.
