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!

Where to add custom code?
You should place PHP snippets at the bottom of your child theme functions.php file and CSS at the bottom of its style.css file. Make sure you know what you are doing when editing such files – if you need more guidance, please take a look at my guide “Should I Add Custom Code Via WP Editor, FTP or Code Snippets?” and my video tutorial “Where to Place WooCommerce Customization?”
Does this snippet (still) work?
Please let me know in the comments if everything went as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting.
