Adjusting your postal code field
To make shipping addresses more accurate and to prevent delivery issues, your customers need to enter a valid postal code at checkout in most countries. The postal code requirement depends on the shipping country or region.
If the postal code field on your store was changed to collect alternate information, such as a phone number or order notes, then you need to restore your default postal code field. Otherwise, your customers won't be able to complete your checkout.
Review the following table to learn more about postal code requirements at checkout:
Postal code | Description | Example country or region |
---|---|---|
Required | The postal code field requires a valid postal code | Canada | Optional | The postal code field can be left blank | Sri Lanka |
Not required | The postal code field isn't displayed at checkout | United Arab Emirates |
