Well, if it's good enough for this group, then it's good enough for me
and I am happy :-)

I read RFC 3066bis, and I didn't get this out of there. ISO 3166 seems
to distinguish between "official" and reserved codes. See the top of
"The content of this document is taken from two sources: The official
code list of ISO 3166-1 and the list of reserved ISO 3166-1 code
elements which contains information on code allocations which are not
officially part of ISO 3166-1"

RFC 3066bis, by contrast, speaks of "assigned" codes. Table 1 of the
above ISO web page suggests that "assigned" codes include reserved
ones: Reserved codes are not counted among "un-assigned" codes. I
think this permits the use of "reserved-assigned" codes (my coinage
here) with RFC 3066bis.

Given the status of this particular reserved code - its intimate
connection with the ISO 4217 currency codes (EU reserved because of
EUR) and its scope of use for "any application" (as opposed to the
usual single standard or field) - to me signal long-term stability,
and suitability for public use like "official" 3166-1 codes.

Of course I agree that it would be good if these reserved codes were
"officialy assigned" and not just reserved. However, the status for EU
is very strong, unlike the status for GG, IM, and JE whose scope is
restricted to the UPU.

No, I am specifically looking to indicate the European Union.

They do, or at least some of them. Their geographical shapes are even
printed on the currency. (I remember specifically French Guyana & the
Canary Islands.)
