Edit a standard field

Find the Form fields editor
In Fields, scroll to Form fields editor. Each row represents one checkout field.
Set the label and placeholder
Use the first text box for the visible label and the second for an optional placeholder. Write a short label that still makes sense after the shopper starts typing.
Choose visibility and required status
Use Show to display a field and Required to require an answer. Email and country stay enabled as core fields.
Save and test the form
Select Save all settings. Submit a test checkout with the field empty and filled, then verify the saved order.

Add a custom field

Select Add custom field. Give it a unique field slug and a clear label, choose its group and type, then set visibility and required status.

Group: Billing, Shipping or Order.
Type: Text, Textarea, Select, Checkbox, Number or Date.
Select options: Enter one option per line in the options box.
Required fields: Test every available express wallet as well as the ordinary checkout form. Wallets may use a different submission path.

ExampleFor an optional delivery note, add a field called Delivery instructions, choose Shipping and Textarea, enable it, and leave Required unchecked.

Helpful entry controls

International phone field: Adds a country dialing-code picker to WooCommerce’s native phone field.
Inline validation: Shows non-blocking email, phone and postal-code format hints. WooCommerce validates the submitted order.
Saved addresses: Lets signed-in shoppers prefill delivery from an existing WooCommerce billing or shipping address. It is not a multi-address-book manager.
