Hi @thiagorangel,
WooCommerce has a native way to gelocate user. Country is easily able to fetch but further geographical data might work country to country.
Sometimes states works too but at zip code level, it is rare to work.
Our cart plugin shows a quick cart and have features to increase AOV. It doesn’t take shipping geography data.
A user can add the zip code on the native cart but I am not sure why user will go to the side cart further. Our product reduces the distraction to go to another page i.e. cart. And lead user straight to the checkout.
So, I am also not getting why user will go to the native WooCommerce cart page and insert shipping details.
If any query let us know.
Thanks!
