Hello Marcin,
Thank you for the clarification.
There’s no integration with WooCommerce user accounts, therefore it requires either manually creating and mapping the form fields, or developing a custom snippet (must use plugin).
The list of the WooCommerce checkout meta field names can be found here.
You can easily map some of the fields, like street address, city, ZIP code to WooCommerce meta fields in User Registration >> Add Custom User Meta section:

However, WooCommerce stores country and state fields in particular format, which should be used instead of the full names.
Alpha-2 format is used for the country codes:

And ISO 3166-2 format is used for the state/province codes, for example:
https://en.wikipedia.org/wiki/ISO_3166-2:US
If your online shop operates in a limited number of countries, you can create Select fields with the country/state names, and values (codes), and then map them to WooCommerce fields the same way as other custom fields, in User Registration >> Add Custom User Meta:

If you need adding lots of countries and states, adding them manually as Select fields would become more difficult. In this case you may consider developing a custom snippet for mapping the large list of countries and provinces to WooCommerce meta fields.
Creating such snippets would be outside the scope of support we provide. You may hire a developer for this kind of advanced customization. For example, check out the WordPress jobs directory here: https://jobs.wordpress.net/

I hope this helps. Please let us know if you have any questions!
