This is correct. It can be reduced to 4" if under a concrete slab at least 4" thick. In a parking lot or driveway it needs to be 24" deep.
Note: this is the depth ABOVE the conduit meaning the ditch has to be this amount+ the diameter of the conduit.

Hi Electric Experts.
Does anyone know what the code is as far as burying electric in a PVC tubing underground? What I am referring to is the depth. How deep does it have to be? An electrician told me 18 inches. Is that accurate?
Thanks in advance.
