VAT number validation

Hi, 
When setting up customers and vendors via data entities I get the following error for some of them: /Letters are not allowed in the VAT number/. 
 
In the /Tax > Setup > VAT > Country/region parameters/ you can define if the check/validation for format is run or not for a specific country/region but where can we see the valid formats that D365 allows for each country format? 
 
Thank you!

    Hi Patricia,
     
    For some countries, the VAT number check is implemented in coding, but not for all. A developer would be able to check what is available. All classes do start with TaxVatNumValidate and have a suffix for the country.
