Hi @ipokkel

As you can see below,
I've modified the code that didn't work in my context, even though I'm on the checkout page (WP 6.6.2 / PMP 3.3.1).

function wp_head_hide_billing_state_field() {
	global $pmpro_pages;
	if ( empty( $pmpro_pages ) || ( ! is_page( $pmpro_pages['checkout'] ) && ! is_page( $pmpro_pages['billing'] ) ) ) {
		return;
	}
    ?>

	<style>
		div.pmpro_checkout-field-bstate,
        div.pmpro_form_field.pmpro_form_field-bstate {
		display: none;
		}
	</style>
	<?php
}

Feel free to use it if it's ok for you.
Thanks again for this code ;)

Thank you, @lagenceoueb, I've updated the CSS selector accordingly. :)
