A unique id number is required to sign up with DAT OnBoard™
For US carriers, this number is either their DOT or MC number. Since Canadian carriers are not issued these, a unique identifier must be selected prior to a Canadian carrier registering.
Once you call DAT at 800-551-8836, we will assign you a unique identifier that will allow you to register. We recommend using your company phone number as the DAT ID when you contact us.
