This challenging task (yet very simple at the end…!) was requested by one of my WooCommerce Support clients. As they trade in USA only, they wanted to force “numbers only” in the ZIP input field, so that letters would not be allowed. Strange WooCommerce doesn’t do this out of the box!

You can place PHP snippets at the bottom of your child theme functions.php file (delete "?>" if you have it there). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"
Does this snippet (still) work?
Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7.3.

Mauricio, thanks so much for your comment! Yes, this is possible – but unfortunately this is custom work and I cannot provide a complementary solution here via the blog comments. Thanks a lot for your understanding! ~R

Hey, amazing work!
I want to make it required that numbers AND letters are written. So, I change
“number” with? Thank you so much.
“text”
You can also edit form type by edit forn field array on form-edit-address.php
Of course – however it’s not a great idea to override WooCommerce templates 🙂
