How can I make the address field mandatory?

Hi @leomostaza, address autofill feature would basically only fill the form field based on inputs from Google API. To ensure that address field is populated, you can handle that in your theme and ensure that end user is not able to submit the checkout address without mandatory fields.

Thanks, but how can i do it?

Please check this page explaining customization for woocommerce checkout fields. You can also refer to sample code snippet here.

Thanks, that works perfectly!
