Plate doesn't come up on there.

Lack of result or unusable display? Because the result is... that there is no result for this plate. Fake one?

Maybe. Thanks for trying !

It's been a while, but I've finally found a new site: Kazakhstan!
http://nomerok.info/m/kazgibdd?carnomer=A740THM&searchButton=+%CD%E0%E9%F2%E8+

Hinted by I-Denev, though I don't know what the starting page would look like, you'll have to start from my link.
You need to enter the number without spaces.

Vietnam, though it does not provide much info aside from the make, weight, VIN (?) and dimensions: http://www.vr.org.vn/ptpublic_web/ThongTinPTPublic.aspx

But in my opinion, only the Kazakh site should be added to the links...

After almost two years of searching I finally found it: Russia!

Before checking a plate, you need to select the oblast. It runs on the same engine as the Kazakh site, but is a bit harder to use...I at first managed to crib results only by searching alphabetically, but then I got it. After selecting your oblast, you type the plate in this format: "lowercase letter-three numbers-two lowercase letters."

I hope it's not too much of a hassle for you to quickly switch to a Cyrillic keyboard...

The link to the Icelandic site needs to be updated. Here is the new link: www.samgongustofa.is/umferd/okutaeki/okutaekjaskra/uppfletting/

Thanks, that's not the first time they change the address of their site...

A friend of mine gave me the address of another site for chilean plates :

http://www.prt.cl/Paginas/RevisionTecnica.aspx

It's quite easy to use : just enter the plate number without hyphens, and the capcha.

Thanks, added

So the Åland Islands are now handed over to Argentina, per the description?

Oops, the problem of copy-pasting without proofreading
