Here's a box art that belongs to a SNES GPS game, in this case Wario's Woods (SNSP-65-GPS).
I'm not going to turn this discussion to one referring wholly to the GPS code, but again it is highly likely that it was imported to this region.
As we can see here this is taken from the German cover (which in turn borrows many elements from the North American one) complete with a column on the bottom referring to the origin of the product (Grossostheim (old address for European headquarters it is now based in Frankfurt), Germany, Nintendo Of Europe, and CE label). Note that everything in the package is in English, including documentation.
So just for reference, I'm going to put up a list of all the countries were GPS consoles and games are known to my knowledge to have happened to be distributed in some way or form. It is most likely missing a few, as it is partly based on recent findings.
In Europe:
*Portugal
*Italy (Some cases)
*Croatia
*Greece
*Netherlands (Very minimal instances. A number of them though were said to have been imported, officially or not I do not know. There were copies of the NES game Mario and Yoshi that had this labelling with black and white dutch/french manual and was known to have been sold in this country by the official distributor (Bandai). Own code = HOL or FAH, shared with France. )
*Spain (Again very rare instances where they would just slap in a cheap manual of the countries native language, own code ESP, which most games used).
*Sweden and Scandinavia (Same story as previous two territories, own code SCN)
Outside of Europe
*Australia (Perhaps for one games only, Killer Instinct for the SNES. It is known that the firm Novagroup were in contact with Nintendo Europe to import some of their games into here, which is quite odd considering: A. that the Australian base for Nintendo has been in operation from 1993 and that B. some European games were already being imported by them. Oddly from the looks of it it does not seem to even bear the rating system for the country at the time. That and GPS Game Boy systems are the only two European related items known to have been imported by Nova Group however I think that it is very likely that there are more distributed by them.)
*South Africa (A variant of this code was released for the NES which bears SAF coding. All games, including for other consoles, were GPS though.)
*Egypt (although I'm not so sure about this one)
*Israel
*Middle East/Gulf regions (Presumably)
Do hit me up if I'm obviously missing a few.
