Thanks, updated
Their urls do not feel very reliable

Another Norwegian plate check site - this one is useful as you may search for the model and you get all the documented plates of the vehicle type in question. It's also very useful if you have some of the number plate digits available as it lists all cars with said digits.

Thanks, I added it

The slovak link doesn't answer anymore (error 403).

Just in case, here's another one : https://www.stkonline.sk/informacny-servis/ceny-technickej-a-emisnej-kontroly

Thanks

Found this website in a discussion about French plates on Avtonomer/Platesmania: https://autorigin.com/

To the French speakers of IMCDb (who can properly read the texts), is Autorigin any good? I actually ran the plates of several vehicles I have on Platesmania and whether it returned any info varied.

Interesting. I entered a random french plate number on Autorigin, and the good thing is, it showed most of the VIN. This can be useful.

VIN : VF3MCYHZJKS19****

It also shows basic data, like these :

Carburant : Gazole
Cylindrée : 1499
Couleur : NOIR
Places : 5

Oscaro.com only shows a single line, like this : PEUGEOT 3008 II 1.5 BlueHDi S&S 130 cv.

A combination of both sites would be better.

Belgium : the link at the existing link isn't answering anymore. But it can be accessed through https://mobilit.belgium.be/en

...and click on "My vehicle, my plate" (also available in Dutch and French).

Thanks

For India.
The link on IMCDb is good but go to "Online Services" is false, it's go to "Informational Services" then "Know your vehicle details".

New link for Australian plates, this is the best one so far as it tells you everything including trim level, transmissions, and even the VIN for any state in Australia:

https://www.gumtree.com.au/p-post-ad-rego-lookup.html?categoryId=18320&adType=OFFER

But it seems to require a login... (is it the right link? It says "Post an Ad")

@JB007> thanks, updated

Sorry, you're right, you do need to log in. My mistake.

Rather unexpectedly, Kyrgyzstan:

Thanks, I'll add it.
I hope that you wrote correctly the country name as I did a copy/paste, I'll not re-type it

The Platesmania forum has a thread for plate lookup sites and I found one for Israel, and I've noticed the Russian website isn't listed yet.

Meshumeshet.com (Israel) - https://meshumeshet.com/
Avtocod (Russia) - https://avtocod.ru/

Thanks

One for Chinese plates, unfortunately, it seems you have to link your WeChat account to use it, and of course, pretty much nobody outside mainland China will have that. Screenshots look promising though.

I found one for Sri Lankan plates... Unfortunately it seems you have to enter your NIC (the Sri Lankan equivalent of SSN) and phone number so unless you're a Sri Lankan national or resident I highly doubt any of us can use this service.

Two sites not added to our list.

New additional one, with more information, for Brazil: https://placafipe.com/
New additional one, with more information, for USA: https://www.vehiclehistory.com/license-plate-search
