HI @dverkade thank you for your report, i'm confusing with your issue, why zip code must be not required ? after you chose tax/default/postcode ? because this field is required -> Settings can be found in: Admin Panel > Stores > Settings > Configuration > General > General > Country options > Zip/Postal Code is Optional for .
So if you chose all you dont have this error validation. And why taxes can remove validation from aip postal code ?

[ghost]

@dverkade Ok, i'm understand that if page load, then this validate the zip code filed, but in my case i have no validation, see attachments.

[dverkade]

@engcom-backlog-nazar if I look at the screenshots you are using Magento 2.3 development. As noted in the issue description we have this issue with Magento 2.2.6.

[ghost]

@dverkade ok, but you created the PR #18633 to 2.3-develop so this issue must be in 2.3 ?

[ghost]

@dverkade the same on 2.2-develop and 2.2.6 instance, i'm do exactly what you mentioned on steps to reproduce.

[ghost]

@dverkade Can you reproduce this on vanilla instance ?

[ghost]

@dverkade, we are closing this issue due to inactivity. If you'd like to update it, please reopen the issue.

[ghost]

I'm able to reproduced this issue by following steps on 2.2-develop and 2.3-develop:

1. Use system value to : Stores > Settings > Configuration > General > General > Country options > Zip/Postal Code is Optional for
2. Add products to cart as guest
3. Proceed to checkout

Can also reproduce..

Still exists in 2.3.0. Just have to set a postcode in "Default Tax Destination Calculation"

Which is set here:
http://Base_url/admin/admin/system_config/edit/section/tax/

Use Xdebug in any active shipping module on calling RateRequest->getDestPostcode(). We observe that:

Magento\Quote\Model\Quote\Address\RateRequest->$_data['dest_postcode'] = Default Tax Destination Calculation
