What it means

The VAT number does not match the national format indicated by its country prefix. This app reports a format error; it does not establish whether the registration is active.

Typical causes

  • The country prefix is wrong or missing.
  • Digits are missing or punctuation was included.

How to fix it

  1. Confirm the VAT number with the business concerned.
  2. Use the correct country prefix and national format.
  3. Remove spaces, dots and dashes, then validate again.

What the rule says (technical)

The VAT identifier does not match the national format of its country prefix, so tax authorities and VIES will reject it.

Correct the number using the national pattern shown, and remove spaces, dots and dashes.
