Top three things to fix

1. Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change.

   Service data ended 1674 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist.

   Effort: Usually one export setting; export on a schedule so it never lapses again.

2. Review the rule documentation for 'missing_required_field' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Missing required field (flagged by the MobilityData validator). See the linked rule for what this affects.

   Effort: Varies.

3. Review the rule documentation for 'invalid_currency_amount' at https://gtfs-validator.mobilitydata.org/rules.html and check the flagged rows in your feed.

   Invalid currency amount (flagged by the MobilityData validator). See the linked rule for what this affects.

Ready to send to the agency

Hi South County Transit Link team, Service data ended 1674 day(s) ago. When the calendar runs out, trip planners stop showing this agency even though the buses are still running. Riders are told the service does not exist. The fix is usually one export setting: Re-export the feed with a calendar that reaches further out, and set feed_info feed_end_date past your next service change. Your feed is produced by Trillium, so the quickest path is usually forwarding this to your Trillium contact. This came from your GTFS data quality scorecard, which checks the feed you publish and lists the fixes in plain language: https://gtfsscorecard.org/agency/south-county-transit-link/

agency_id equals NTD ID (optional): Not checked yet. This feed provides agency_id. For RY2026, keep one stable value for each NTD reporter represented in the feed and crosswalk it on the P-50 form. The value does not need to equal the five-digit NTD ID; we do not have that ID on file, so the optional equality comparison is not checked yet.
