WooCommerce: Disable Checkout Field Autocomplete

By default, WooCommerce adds the “autocomplete” attribute to almost all checkout fields. For example, “billing_phone” has “autocomplete=tel”, “billing_country” has “autocomplete=country” and so on.

When logged out or if the logged in user has never done a purchase before, the WooCommerce Checkout page fields are possibly autofilled by the browser based on saved data / addresses.

Today, we’ll take a look at how to disable this autofill behavior, so that the customer is forced to enter data inside an empty input, and maybe in this way you can apply your custom validation or pattern, such as a specific phone number format. Enjoy!

By default, WooCommerce allows empty checkout fields to autocomplete with browser data. Let’s disable this for a specific field so!
