How Do I Remove the Phone Number Field on My Checkout?
For a product with editable checkout fields, open its editor and select Checkout. Find the Checkout Fields section.
To remove the phone field, click the trash icon beside its row.
To keep the field but make it optional, turn off Required instead. The field stays visible.
Save your product changes and check the published checkout.
To add it again, click Add field, then choose Phone from the new row’s type dropdown. Set the label and Required setting, then save your changes. Add field initially creates a Custom row; selecting Phone changes its type.
