# IFOPT stop id (DHID) (`ifopt_stop_id`)

> **Draft.** Draft records have not been reviewed yet and may be incomplete or wrong; do not treat them as authoritative for legal or compliance decisions.

Identifier of a stop place, an area of it or a single quay under IFOPT (Identification of Fixed Objects in Public Transport), the European reference data model for stops. Parts are separated by colons: a lower-case country code, a regional key, the stop number, then optionally an area and a quay. Germany publishes these ids as DHID (deutschlandweite Haltestellen-ID) with the five-digit district key (Kreisschlüssel) as the regional part, as in de:05966:60521 for a stop and de:05966:60521:1:1 for one of its quays.
