1964 VWs don't have VIN numbers, they have engine and chassis numbers.
The engine number is stamped into the engine case just below the generator stand.
The chassis number is in three places. The first is on a data plate somewhere near the spare tire well in front. The second is on a plate in the windshield --it's pretty much straight ahead of your left hand while you're holding the steering wheel. And the third is under the back seat on the tunnel.
BTW, do not be alarmed if the number on the transmission tunnel doesn't match the other two numbers; when they were still importing these cars they were common enough that someone who had a rusted-out chassis would go to the junkyard and buy a Bug someone rolled. It's pretty easy to get the body off the chassis, so you'd put your good body on the good chassis, the rolled body on your rusted-out one and have the now-completely-ruined Bug hauled back to the junkyard.
usually, the 3rd number of the vin correspond to the year of the vw. In this case, it would be 1977.
where is the location of the vin tag for a 1973 VW thing

The VIN number is the same as the Chassis number. For a 1964 it should be located underneath that Back seat. Its the main Metal part that is directly in the middle of where the seat sits. You might have to clean the area, but it will have the Chassis number on it. It will be a 7 digit number.
Vin Plate
VIN # is found under the rear seat on the wishbone part of the cassis.
