Customer - Postal Code table

Hello,

I am looking for the table to get the customer Postal code details based on the country.I have tried linking BUT000 & BUTADRSEARCH with BP GUID , but no data.

Can some one please advice me on this .

And also want to know, is there any GTS standard country specific Postal code length.for India 6 digits and for Srilanka 5 digits ..like this.

Thanks
