Where do you go to get proof registry issued same plate number you have to another person meaning there are 2 plate s with same number on different trucks.

If no luck getting thru online go directly to RI DMV in Cranston..third floor ...go to the reception desk and ask for a supervisor. She will tell you the best way to get this error corrected. One of the 2 parties involved is driving illegally. They are very helpful at this DMV.

You should contact the DMV administrative office by using the online form here: http://www.dmv.ri.gov/feedback/
