What/where is "Numbers matching"?

[Tom999w]

I have matching info on all the tags (dashboard vin tag, front trunk tag, door tag, engine compartment tag). So my question is, are the rest of the "matching numbers" on the block, frame, and transaxle? If so, where?
 
I did a search on this site and came up with no clear results.

Chassis on the left Y-section, body number on the lip facing the engine compartment under the rear window, chalked number in the doors, engine tag on the block.

There is a number on the transaxle as well but not usually noted on the ID plate.

    Yep JB is correct , I was taking pictures of this for another member. It isn’t easy to see .
Appropriately 7/32” in height.

Great, thank you very much everyone. This info might help other people too. I'm going to look for the numbers today.

I have the car number on the right side of the tunnel in the cabin. It’s a Federal car, so the passenger side.

And the chassis was replaced due to damage, so no number on it. Just noting that for future searchers.

Oh yes, that makes sense..

So I ran out and dug some of the snow away and found the body number but it doesn't match any of the other numbers on the data tags. Is this normal?

[Tom999w]

Also, can you clarify where the transaxle number is located? The data tag in the front trunk says that the transmission number is #1220 but I can't find that number anywhere on the trans...

Body numbers should be "close" to the ID number but are virtually never the same.

Transaxle number is on a tag attached to an upper nut/bolt one the rear cover.

You're right, #Vin 0628, body #0659..
