agency_id and NTD ID: Not checked yet. Setting your GTFS agency_id to your five-digit NTD ID is an optional way to line a feed up with its National Transit Database record. FTA links the two on your P-50 form, so it is not a required feed change. We don't have your NTD ID on file, so this is not checked yet.
