The low coverage rate of the EUID for some countries is due to the lack of a standardized EUID.
Each country uses its own format for the EUID (European Unique Identifier), leading to incompatibilities and challenges in data collection.
Lack of Harmonized Implementation
The EUID was introduced to facilitate the exchange of company information within the EU. However, member states have implemented different systems and formats for generating the EUID. The absence of a standardized format at the EU level complicates harmonization and contributes to the low coverage rate.
Format Differences
For example, in France, the EUID is structured as FR + Greffe Number + SIREN. In other countries, completely different combinations are used. These discrepancies make it difficult to consistently capture and process EUIDs across borders.
Each country uses its own unique format for EUID. For instance, in France, the EUID is structured as FR + Greffe number + SIREN. The main challenge is the Greffe number, which is not available for all companies. It is often missing from master data and can only be found in financial statements, making it difficult to retrieve and evaluate. As a result, the coverage rate for EUID remains low for French companies.
