ID Crosswalks

These crosswalks match Transitland Onestop IDs to the identifiers other transit data systems use, so you can join Transitland to data you already have.

Each crosswalk is an external identifier that Transitland Atlas tags on Transitland operators or feeds. Browse them here, download them as CSV, or query them through the GraphQL and REST APIs.
