Belgian Tax IDs

Businesses in Belgium can use the VAT or RNPM (Registre National des Personnes Morales) number as the tax ID for reporting to the government, or they can use the unique enterprise number (numero unique d'enterprise) as the tax ID for reporting. The unique enterprise number must always begin with the character 0.

You can enter the VAT, RNPM, or unique enterprise number into the system with the preceding characters BE or without these preceding characters. VAT and RNPM number strings are either 9 or 11 characters, depending on whether the preceding BE is entered. The unique enterprise number string is either 10 or 12 digits, depending on whether the preceding BE is entered. For example, these character string structures are valid:

  • BE 12345679 (VAT or RNPM with preceding BE and with a space between BE and the VAT or RNPM).

  • BE12345679 (VAT or RNPM with preceding BE and without a space between BE and the VAT or RNPM).

  • 123456789 (VAT or RNPM without preceding BE).

  • BE0987654321 (unique enterprise number with preceding BE).

    The maximum number of characters allowed by the system is 12. Therefore, if you enter a preceding BE with the 10-digit unique enterprise number, you cannot include a space between BE and the 10-digit number.

  • 0987654321 (unique enterprise number without preceding BE).

When you enter a VAT, RNPM, or unique enterprise number, the system verifies that the length of the string is valid and that the characters are valid, such as the unique enterprise number beginning with 0 (zero). The system also compares and validates the check digits. If any of the validations fails, the system displays an error.
