The Autocomplete entity ID module extends the standard entity autocomplete. It allows users to see autocomplete match by entity id and not only by entity labels. It provides a form element, entity reference field widget, and a possibility to enable globally for all existing autocomplete fields. How to use it: Create "entity_id_autocomplete" form element instead of "entity_autocomplete" in your custom code. Configure entity form mode to use "entity_reference_autocomplete_id" widget for entity reference fields.
