uic_ref in the Baltic states generally seems to be mis-tagged. The codes do not match with the values on https://www.interrail.eu/en/plan-your-trip/interrail-timetable#/ and https://www.cfl.lu/en-gb/timetable (open browser devtools to see them in the responses).

Before I start fixing them, I'd like to understand how this happened. Which data source did you use?

Meines Wissens nach existieren IBNRs nur für Bahnhöfe die in UIC Merits enthalten sind. Vermutlich liefert die Bahn in Nordmatzedonien keine Fahrplandaten an UIC Merits.

Hi!
I needed the ibnr to match stations from the Deutsche Bahn Hafas API to OSM. I found out the ibnrs by querying their API with a small script, but the API has gone defunct since.
You can however use the ÖBB endpoint instead with my fork of pyhafas (https://github.com/jbruechert/pyhafas/commits/zpcg-scraper/).

The script is then really simple:
```
from pyhafas import HafasClient
from pyhafas.profile import OEBBProfile
import sys

client = HafasClient(OEBBProfile())

locations = client.locations(sys.argv[1])
print([(s.name, s.id) for s in locations])
```

I found 7200012 as the UIC code from the Deutsche Bahn API, were did this information come from?
