TxDMV Number & Unified Carrier Registration

Motor carriers operating intrastate commercial motor vehicles on a road or highway in Texas must get a TxDMV number.

TxDMV Number

The federal Unified Carrier Registration (UCR) Agreement requires individuals and companies that operate commercial motor vehicles in interstate or international commerce to register their business with TxDMV and pay an annual fee based on the size of their fleet.
