Your "Customer ID" will be the code from the RFID sticker that was affixed to your windshield when you purchased your plan. This is an 11 digit number separated with a plus (+) symbol. (e.g. 12345+123456). If you were not issued an RFID sticker you should enter your license plate number. Note: License plate numbers should not include spaces and must include the issuing state code. For example, if your plate number is "ABC 123" and issued by the state of Nevada, you would need to enter "ABC123-NV".
The Customer ID field refers to the RFID tag on your vehicle, if you were not issued an RFID tag then your Customer ID is your license plate with "-CA" or your equivalent license plate state abbreviation after your license plate.
Example: ABC1234-CA
Example: 12345+123456
