Rename the label of AddressField::ORGANIZATION from "Company" to "Organization"

I have a request for one of our clients to change the 'Postal code' label to 'Post code' saying Postal code is an American thing. We are based in Australia.
Since the labels are not configurable from the back-end, is there any proper way to do so through the hooks and without translations definition?
I tried the method mentioned at https://docs.drupalcommerce.org/commerce2/developer-guide/customers/addr..., however in my case, the $form_id is not same on different pages for a same form. It is like

'webform_submission_get_in_touch_node_36877_add_form' 

whereas I expect it to be

'webform_submission_get_in_touch_add_form'

(it is right on some pages though_.
So the above link does not help in my case.
Any workaround would be appreciated.

Thank you
