Modify The Code

You can of course modify the code to generate a WooCommerce order number of your own format.

Have a look at the WC_Order object code reference to see what data is available to you.

Where To Put The Code Snippet?

This code snippet should go in your active theme’s functions.php file.

Add it to the bottom of the file, before any closing ?> characters.

It’s always a good idea to take a backup of your functions.php file in case anything goes wrong – you can just copy the old code back in again.
