NB: This will only add the event handler to matching elements which exist at the point when your code is run. If you modify the document at any point to add new matching elements, they will not have the event handler attached.

You would probably be better off using event delegation[^]. Since you'd only have a single event handler, it can even be more efficient.
JavaScript
document.addEventListener("keydown", (e) => {
    const el = e.target;
    if (el.classList.contains("phoneNumber")) {
        console.debug(el.id, el.value);
        el.value = formatPhoneNumber(el.value);
    }
});
