I recently purchased a used car from a dealership. They also submitted my paperwork to the DMV. A month later I was asked to go pick up my registration and license plate. I went on the DMV website and tried to add my plate number and vin and I got this error message

“The license plate number or the last 5 digits of the VIN does not match the vehicle's registered information. Make sure you have the correct information and try again.”

Is there any reason why the DMV doesn’t recognize my plate number when the number is issued by the same office? I am just trying to do address change.
