EORI Number – What is it? How to obtain one? How to verify its validity?

In today’s global trade landscape, complex import and export processes necessitate accurate identifiers. One such crucial identifier is the EORI Number. This concise acronym stands for “Economic Operators Registration and Identification” and holds significant importance for entities engaged in international transactions. In this article, we will discuss the nature of the EORI Number, the process of obtaining it, and how to ensure its validity.

Understanding the EORI Number

The EORI Number is a unique identifier assigned to business entities participating in international transactions, such as imports and exports. It serves as a pivotal identification number utilized within the customs systems of the European Union to facilitate customs processes, monitor trade operations, and ensure compliance with regulations. The EORI Number enables customs authorities and other relevant institutions to track the trade activities of entities and secure supply chains within the realm of international trade.

Structure of the EORI Number:

The structure of the EORI Number depends on the country of origin of the entity. For domestic entities and third-country entities, the structure may differ slightly, but for both, the EORI number has a maximum of 17 characters and begins with the prefix of the country in which it was assigned, followed by a string of characters.

Obtaining an EORI Number: Procedure and requirements

Attaining an EORI Number is a crucial step towards conducting international trade operations efficiently and in accordance with the law. The following are the procedure and requirements that are essential to comprehend in order to obtain an EORI Number.

1. Submitting an application to the relevant customs authority.

In order to obtain an EORI Number, it is necessary to submit an application to the appropriate customs authority in the country where the company is headquartered or operates. The application can usually be submitted electronically or in paper form, following the guidelines available on the customs authority’s website.

2. Accurate and comprehensive information.

When submitting the application, it is imperative to provide accurate and comprehensive information about the company and its activities. This includes details such as the company name, tax identification number, registered address, nature of activities, as well as information about international transactions in which the company intends to participate.

3. Preparation of necessary documents.

Depending on the country and customs authority, additional documents may be required to confirm the identity and legality of the company’s operations. These may include registration documents, founding deeds, commercial agreements, or other proofs of activity.

4. Allocation of EORI number.

After submitting the application and providing the necessary documents, the customs authority assesses and processes the application. Upon favorable consideration, the company is granted a unique EORI Number. This number can subsequently be used in international trade operations.

Why is Validating an EORI Number Important?

It is important to regularly check the validity of the EORI Number. Changes in tax law or customs and tax regulations can affect the status of an EORI Number, so regular verifications are crucial to avoid complications and delays in commercial operations.
