recently I have been asked by a customer where the documentation of the integration unit codes is located: there is a dead link within the current xRoute API (Waypoint class) and I already forwarded this issue to product development.
Within the xRoute server you can find a list of the integration unit codes (requires a running xRoute!).
Please be aware that some IUCs are covered by a set of codes (sub-iu's), e.g. Russia (formerly known as "16") consists 8 different codes 1016, 2016, 3016, ... 8016. So the unit code itself is described by the 3 closing digits.
This is also the case with
- 100 = USA
- 091 = India
- 200 = Canada
- 761 = Australia
