If you found some license plate, which contains RFC3, then you can send the message here. Of course, you can register again in the issuing authority and get a new identification mark, but why not to try something simpler and more effective?

If you are ready to give preference to something cheaper we want to invite you to our page. Here you will find a long list of seven-digit numbers, beginning with RFC3 that will help you to find the owner of the vehicle or to search your car license plates in the case you have lost them.
