Online Validation of Foreign VAT Identification Numbers

Mandatory Online Validation of Foreign VAT Identification Numbers from July 2025

In a letter dated 6 June 2025, the German Federal Ministry of Finance (BMF) clarified that, starting in July 2025, requests to verify foreign VAT identification numbers (VAT IDs) must be submitted exclusively via the digital verification system of the Federal Central Tax Office (BZSt). Written or telephone inquiries will no longer be processed.

Background

Businesses engaged in intra-Community supplies within the European Union are legally required to validate the VAT ID of their customers. Failure to do so may result in retroactive VAT assessments.

The BZSt online verification system—accessible via the BZSt portal or XML-RPC interface—is free of charge and available 24/7 (subject to possible maintenance windows).

 

Types of Requests

  • Simple request: Verifies only the validity of the VAT ID.
  • Qualified request: Also confirms the business name and address associated with the VAT ID.

Both types of requests must be submitted digitally via portal or interface as of 20 July 2025.

 

Amendments to the VAT Application Decree

The BMF letter of 6 June 2025 (Ref. GZ III C 5S 7427d/00014/001/002) revises Section 18e.1 of the VAT Application Decree. Key changes include:

  • As of 20 July 2025, only digital requests are permitted.
  • Name and address verification remains possible as part of a qualified request.
  • The rules apply to both single and bulk inquiries via the interface.
 

Implementation and Transition

The new regulation takes effect on 20 July 2025. From this date onward, written, telephone, or fax inquiries will no longer be valid.

Companies should ensure their software and workflows are adapted to use the BZSt portal or XML-RPC interface for processing both qualified and simple requests in a structured manner.

 

Relevance for Franco-German Business Relations

For Franco-German enterprises and cross-border supply chains, compliant verification of VAT IDs is essential. The new system offers:

  • Legal certainty: A single, standardized digital process – no hybrid approaches.
  • Traceability: Qualified confirmations are stored electronically – no paper required.
  • Digital efficiency: Streamlined processing for both individual and bulk checks – greater compliance efficiency.
