When it comes to the checkout page in your Shopify store it is, unfortunately, unable to be adjusted as it needs to meet the requirements for processing the credit cards. The coding to that is locked so you won't be able to adjust it, our team won't be able to make customizations for you and neither will the Shopify Experts.
All aspects of the page (Billing Address, Country, Postal Code) would need to be filled in in order to verify the credit card. However, if your country doesn't use postal codes I do see how this could pose as an issue for you.
What I recommend is that you make a note on your cart to tell your customers to use a generic postal code if they don't actually know or have one of their own. To do this you would need to edit the code for your cart page. By going to your Store Admin and clicking Online Store > Theme > Actions > Edit Theme Code > cart.liquid you could add some text for your customers.
If you don't feel comfortable doing this you can reach out to a Shopify Expert who I am sure would be happy to get this done for you.
Generally those types of things go at the very beginning or the very end of the file. However, in no way am I able to say that I am a professional when it comes to coding.
In that case you might want to get a Shopify Expert to take a look.
If you have any other questions please do let me know.
if i am not able to remove the postal code , can i put a default number ?!, the same goes for the governorate as i only support one governorate in cairo not all , can i put a default one ?!! like Cairo , so customer in both cases aren't required to provide any info for those , and in case he wants to change he can change them .
Hi, apparently the postal code, does not apply to all the countries... If you chose for example United Arab Emirates as Country, there is not postal code. So, this is not definitely necessary, and at least Shopify, should be able to let the merchant to select the Postal Code as "optional" any chance to get this done? Big Commerce actually does allow to do so.
