- Primary service sources are preferred for app names, app support, and service-positioning claims.
- Before Korea avoids pretending to have personally tested products, apps, or places unless that is true.
- When a fact can change, guides remind readers to re-check close to their trip.

Trace each event claim to the source that owns it
Korea event information should be checked claim by claim. The artist or organizer owns the event announcement, the designated seller owns the checkout policy, the venue owns facilities, and the transport operator or city owns route changes.
| Claim | First source to open | What it cannot prove alone |
|---|---|---|
| Event date, venue or seller | Artist, agency, promoter or official community notice | Current checkout availability |
| Payment, ID, cancellation or pickup | The seller named by the event notice | Rules for a different event or sale round |
| Gate, access or bag facilities | Venue operator plus exact event instructions | A temporary stage or security layout |
| Subway, bus or road change | Transport operator or local government | That crowd conditions will remain normal |
Start event claims at the artist’s official community such as Weverse, then follow the notice to the named seller. Use the venue operator for place facts, the Seoul Metropolitan Government public-transportation guide for official subway route and station tools, and the Korean Law Information Center for law rather than a fan summary.
A source being official does not make it responsible for every claim on an event page. Check the publication date, exact event scope and which authority controls the decision.
