What a delay certificate is
A document from the transit operator confirming a service ran late, usually listing the date, line and length of the delay. It’s common in South Korea and Japan, and some operators elsewhere offer delay verification letters on request.
Where to get one
| Method | Notes |
|---|---|
| Operator website | Pick the date and line, print or save. Fastest where offered |
| Station office | Ask staff at the station |
| Operator app | Some operators offer it in their app |
Different lines in the same city can be run by different operators. Get it from the operator of the line you rode. Availability, time limits and minimum delays vary, so check that operator’s own information.
Handing it in
- Message before you’re late; attach the certificate afterwards
- If the certificate’s delay and how late you were differ a lot, say so honestly
- If it keeps happening, changing your route or leaving earlier beats collecting certificates
