TripId

Tripid, often written as TripID, is a term used in information systems to denote a unique identifier assigned to a single trip or journey within a dataset or workflow. In practice, a TripID ties together records such as reservations, payments, itineraries, and service events for that journey. It serves as a stable reference point across systems and services.

Variants in naming reflect programming and database conventions, including trip_id or TripId. Trip identifiers are typically stored as strings or numbers and may be generated as sequential integers, random UUIDs, or composite keys that embed date components or service type.

In travel and transportation, a TripID links a passenger’s itinerary with service events such as check-in, boarding, and payment. In ride-hailing, logistics, and delivery, it identifies a task or trip instance for tracking, billing, analytics, and customer support. In public transit, each scheduled service run is associated with a TripID in timetable and real-time systems.

Generation and governance emphasize global uniqueness, immutability after creation, and efficient indexing. Some identifiers encode metadata, while others are opaque to reduce information leakage. Privacy and security considerations may influence whether a TripID reveals system structure or authentication context.

In data models, TripIDs function as primary keys or as foreign keys that join related records, and they are commonly indexed to support fast lookups across reservations, payments, and events. They enable cross-service reconciliation, auditing, and troubleshooting across the lifecycle of a trip.
