## Notes

- **Source**: the JSON Thailand Post's own tracking page (track.thailandpost.co.th) reads. If that refuses, S10 numbers fall back to the UPU's public Global Track & Trace, and the rest to the same lookup run in a browser session.
- **Coverage**: domestic and international items, with Thai post office names and times in Bangkok time (UTC+7).
- **Times**: scans at a Thai office (code starting `TH`) are converted to UTC from Bangkok time. Other scans carry `localTime` only.
- **Sample note**: the sample above is illustrative.
