[PS 1.5.1] Check if VAT Number or NIN is correct

[Pepozzo]

Hello!

 

I'm using the italian version of Prestashop 1.5.1.

 

I've enabled the option to require a NIN or a VAT number. But i would like to know if is possible to check them if they are correct or not. About the NIN, should be set as request the date of birth field and the birthplace field (and i think i've also to add this last field).

 

Any suggestions? Is it possible to do?

 

Thanks
