What is the minimum cover requirement for a underground service using pvc conduit encased in concrete under a driveway?

Table 300.5 requires 12 in. in a trench below 2 in. thick concrete. Under a driveway it requires 24 in. of cover, but doesn't mention being encased in concrete. I don't know which rule to follow.

I would check with your POCO to see what they require.
 
Use the worst case depth for the whole run if possible. Take Roger's advice and check with the POCO. You may be OK per NEC but the POCO may have some other requirements
