What the registration shows
Diaz Service is registered as an intrastate carrier, meaning it is set up for moves that stay within California. It does not need interstate authority for those moves, but it cannot legally carry a move to another state. For in-state moves, California requires every company that moves household goods within the state to hold a Household Mover permit from the Bureau of Household Goods and Services (BHGS), which took over this role from the CPUC. Movers must show their permit number (often called a Cal-T number) on their vehicles. Use the BHGS license search to check the permit is active and the mover is insured.
With 2 trucks, Diaz Service runs a larger fleet than about 54% of the 114 registered movers in our San Diego directory (median: 1).
It has been on the USDOT register for about 6 years (first added 2020), compared with a median of 6 years for San Diego movers.
