**Solution
**You would have to disable zip code validation on your Card Address verification mechanism in order to create customers via APIs without passing the zip code information.
Please navigate to Settings >> Billing LogIQ >> Card Address Verification >> Uncheck ZIP/Postal

Note: 1) If ZIP codes are passed via API for the billing address, they'd be validated invariably. Ensure that you do not pass the 'card[billing_zip]' parameter if you do not have the zip code information.
