Your National Registry Number was provided to you when you first registered with the NRCME. It is also located on your National Registry Certificate. This is the same number you are required to place on all of the driver examination forms and is 10 digits long.
In addition, if you are certified, you should be listed on the National Registry public search tool which provides your National Registry Number. To access this information, go to the search tool in the middle of the page at https://nationalregistry.fmcsa.dot.gov . If you are still unable to your National Registry Number, please contact technical support by completing the Technical Support Form located at https:fmcsa.dot.gov/national-registry-technical-support-request-form and email it to FMCtechsup@dot.gov .
