The `autocomplete` attribute does not accept `"telephone"` as a valid value — the correct value is `"tel"`.

The `autocomplete` attribute helps browsers autofill form fields with previously saved user data. Each field type has a specific token defined in the HTML specification. For phone numbers, the valid token is `"tel"`, not `"telephone"`. Other related tokens include `"tel-country-code"`, `"tel-area-code"`, `"tel-local"`, and `"tel-extension"` for more granular phone number parts.

Using the correct token ensures that browsers can properly suggest stored phone numbers to users, improving the form-filling experience.

<label for="phone">Phone number</label>
