You can activate the post code / zip validation in the Shoplazza admin. When customers fill in the post code / zip during the checkout process, requesting an order, it checks the order's shipping address for any formatting that might cause shipping issues. The format of the post code / zip will be automatically verified. Countries that support post code / zip verification include the United Kingdom, the United States, Brazil, Chile, Mexico, and Colombia.
- From your Shoplazza admin, go to Settings > Checkout.
- Navigate to the Post code / zip validation section.
- Choose countries / regions that need Post code/ Zip validation and switch on the button to enable the feature.
4. Click Save to complete the activation.
Format check for the United Kingdom is activated by default, and can not be disabled.
