Done

Yes - add all four if there's room. As said, there's no single best site, so folk will have to learn how to use a mix to get the best info. Sometimes DVLA is the best source.

Sites can also change over the years getting redesigns which drop some info fields or adding new ones. So it's always fluid.

I was surprise that those listed on the page seemed a little out of date, as a few years ago they were good. But I guessed that IMCDb staff switched to other ones.

I can add multiple ones to the page, do I add the four that you suggested or only some?

Other sites give more detail than carcheck123.com . It showed my Kia Ceed correctly, but did not mention it's an estate, a Ceed 2 (trim level) and just said diesel instead of 1.6CRDi EcoDynamics

Another example from earlier tonight - X617 JDW . It shows as blue Mondeo petrol, other sites show 1.8 Verona 5 door, built in Belgium.

So there are better sites for our purposes. I don't use mycarcheck or cazana either, as their info is only basic. My usual first stop is https://www.autocheck.co.uk , but they have gaps, some silly entries and some marked as "Unknown Unknown" entries. https://cardotcheck.co.uk is superb for detail, but only allows you a few (5?) enquiries per day.

I'm not sure what to suggest as The Best Site, because they all have quirks. Some of the apparently good ones delete data fairly quickly if DVLA have cleared out the records, which seems to happen more often now. Maybe https://www.vehiclecheck.co.uk/?sc=303 for an easy general site or https://www.checkthecar.com , but both are quick deleters.

It seems OK to me.

What do you think about https://carcheck123.com/ for UK plates?
The owner asks me to add to the list because it returns more info.
The few tests I did seemed indeed return a little more info than those already listed, https://www.mycarcheck.com/ and https://cazana.com/uk/vehicle-check
Do you confirm?
Or are there other sites that I should list instead of these maybe for UK plates?

Yes, B is the city plate code for the Jakarta metropolitan area.

If I understand this correctly, the second link is only valid for cars with a plate beginning with a B ?

Thanks, I'll add these to the list

As Exiv96 asked, plate check sites for Indonesia, here y'all go.

There's also apps too, currently were e-Samsat and Samsat Digital Nasional.
