Zoho should consider implementing ISO 3166-2 standards for countries and regions in address dropdowns.

It adds a lot of noise in the data when items added programmatically conform to ISO 3166-2 (e.g., TX for Texas, CA for Canada, etc.), but the few items entered manually have something different.

This is especially noteworthy in the US, as the default Zoho entry is U.S.A., which is never really used here.

It would also be nice to have the option to lock those fields to only accept drop-down input, as well.

Thanks for the consdideration!
