Hi Jaap,

Thanks for sharing the official document! As far as I can see, it seems that the Short name is marked as TAIWAN, PROVINCE OF CHINA.

https://www.iso.org/obp/ui/#iso:code:3166:TW

I will ask RIPE Support to check which ISO 3166 they implement, and back to here ASAP.

Thank you!

Best,

Tsung-Yi Yu

It does not. It only lists the subdivisons of the entities mentioned
in ISO 3166-1

No, it (*) mentions 3166 but refers to 3166-1 explicitly.

The wiki page you mention (https://en.wikipedia.org/wiki/ISO_3166-2)
is not the official standard. apart from that, it says that ISO
3166-2 "defines codes for identifying the principal subdivisions
(e.g., provinces or states) of all countries coded in ISO 3166-1".

For official information about ISO standards one should consult
iso.org itself. For country codes, see
<https://www.iso.org/iso-3166-country-codes.html> as as start.
