VAT Number Validation Feature

The VAT Number Validation feature in CommBilling ensures compliance with EU tax regulations by automatically validating the VAT numbers of your customers

This feature is essential for businesses operating within the European Union, as it simplifies tax management and ensures that transactions are processed correctly.

What is VAT Number Validation?

VAT number validation involves verifying the authenticity of a customer's VAT identification number to ensure it is valid and registered. This is crucial for transactions within the EU, particularly for VAT-exempt B2B transactions, where valid VAT numbers are required to apply exemptions.

How CommBilling Handles VAT Number Validation

  1. Real-Time Validation

    • CommBilling uses the EU’s VAT Information Exchange System (VIES) to validate VAT numbers in real time.

    • Once a VAT number is entered, the system cross-checks it with the EU registry to confirm its validity.

  2. Error Notifications

    • If the VAT number is invalid, missing, or incorrectly formatted, CommBilling notifies you immediately.

    • This allows you to resolve issues before completing the transaction, ensuring compliance and reducing errors.

  3. Automatic Application

    • For valid VAT numbers, CommBilling automatically applies the correct VAT rules based on the customer’s location and the type of transaction (e.g., VAT exemption for qualifying B2B transactions).

  4. Record Keeping

    • All validated VAT numbers are stored for audit purposes, providing transparency and proof of compliance during tax reporting or inspections.


The VAT Number Validation feature in CommBilling simplifies tax compliance for businesses operating within the EU. By automating the validation process, reducing errors, and ensuring accurate tax handling, this feature saves time and ensures your business meets regulatory requirements.
